Update: I just received the 3D Print from the 'Free 3D Printing' Group yesterday(Nov 3, 2012). It look a little different than I used in the tutorial because I added more parts in the 3D model file, since I got some space left to fit 3x3x3' cube. I got a chance to play with Autodesk's. I spent sometimes to get myself familiar with 123D, and found that it was very easy to use with a lot of features that I could use to create a professional quality 3D models. This hands-on tutorial is written for anyone who want to make 3D Print. In this tutorials, you will learn to use 123D through a series of hands-on exercises.
After reading this tutorial, you can use 123D to visualize designs of the things that will actually be built. You will be guided through the basics of 3D manipulation in 123D, and the principal ideas involved in displaying complex 3D objects, and will be ready to create the simple objects that will get you that first 3D Printing object. You will learn how to save and export files directly from 123D program to send to fabricator, such as (Now, closed.) or anyother 3D Fabricators.
On the way, you get to do something you can see with your “looking glass”, you can create 3D parts, robots, objects and subjects of any type. Goals. Sketch/design the models. Getting to know the 123D application. Use 123D application to create various small 3D models of robot's parts, ears, eyes, shoulders and hands. Combine (join) these parts together into one single piece. Submit the model to the Instructables' 'Free 3D Printing' Group, or to 3D Print fabricators.I will introduce to you various methods to create 3D models starting from basic drawing methods as used in creating ear and complex methods to create 3D models as used in creating eyes with eyebrows.
By combining (joining) small individual 3D Models together, either from the same project or from different project. We could save time and do not have to submit each part individually. And we could avoid waiting for each part to be delivered many times before using them in the project(s). Another benefit of combining (joining) models together is that if the combined model has the size which is smaller than 3x3x3' cube, we could submit the model to 'Free 3D Printing' offer to have it made if you are not in a hurry! But you need to write up an instructable and sign up as a member, to qualify. Not only you could use this methods for 'Free 3D Printing' here at instructables, but you could also apply the methods with your 3D model to be done ( but not free) at Shapeway, Ponoko, etc.
(which allow you to print a larger 3d model for example a model with a footprint of 4x6', etc.) Note: I submitted the 3D Print file as used in this tutorial to our 'Free 3D Printing' Group, but it is still in the queue to be printed. I will post the picture as soon as I receive it. The DesignsI designed the ears, eyes, shoulders, and hands for my robot project,.All the parts are only decorative pieces for the robot, only the eyes that I may want to put the 5mm diameter LEDs inside.And the parts will be fit into the round existing openning, for example eyes will be fit in 10 mm diameter openning, and ears will be fit in 20 mm diameter openning. And both shoulders and hand will be fitting into round Acrylic tubing with 1' (25.4mm) OD (Outside Diameter) and 7/8' (22.225mm) ID (Inside Diameter).
So the designs will somehow have the round plug attached to one end, as shown in the sketches below. The SketchesWhen I was working on the new project, I usually transfer the idea I had in mind into the paper. Sometimes I only doodling on the napkin, just like other designer/inventor did!Later I would refined the napkin sketches to realizable design and something that make sense. The other consideration is that the design should compliment the existing object.Sketches below (no.
1, 2, and 3) are not really 'napkin sketches', they were refined sketches. At this stage all the dimensions are in Millimeter. The Finished ModelWe are going to use 123D to create 3D models of ears, shoulders, hands, and eyes with eyebrows as shown in the four-view renderings ( Top, Front, Left, and Perspective) with the white label no. 1, 2, 3, and 4.Then we will combine or join them together and send the model to make 3D print (at the Free 3D Printing' Group) as one piece, in one single.stl file. (As shown in the last rendering image in this step.) The Profiles and DimensionsIn order to make these exercises moving smoothly, I had prepared the sketches of cross-sections with the dimension of the ear, shoulder, hand and finger, and eyes with eyebrows.We will use them as the guide to draw them and we will transform them into 3D solid model in 123D.We are going to create all of these 3D models using the dimensions shown on each of the cross-section.The dimensions all are in Millimeter. (as the default dimension in 123D.). Down the left hand side of the screen is the Feature Browser Menu, it contains the structure of the components of the 2D sketch and 3D model(s).
We use this menu to select, deselect, enable or disable (show and hide) the node content of the component.You can edit the features in the model by clicking on the Node in the Browser.You can also show and hide the Origin Planes and annotation planes from the Browser and switch between pre-set views.Clicking the Cross makes the 'Feature Browser' DISAPPEAR! To get the Feature browser back by going to Menu Options Controls 3. Main Tool Bar. After we learned about the UI (User Interface) and Navigation systems of 123D app.
We are going to practice a little bit before going into the real stuffs.Let's open 123D app., if you are not already. After we got the 123D ready. First Exercise: Drawing Setup1.
Use the 'View Cube' to set our drawing plane to TOP plane.Move mouse over the TOP plane of the 'View Cube' until the top view cube got highlight in blue. Click or drag left mouse button to control the 'View Cube'2. Setting the grid interval and snap value.Move the mouse to 'Snap Bar' menu (at the lower right hand corner of the screen) Check if the unit if in mm.
(Milimeter), if not change it, by move the mouse over the unit, the selection list will appear move the mouse over the mm and click to confirm.Next, we will set the grid spacing. The grid spacing is the value shown in the rectangle on the right hand side next to the unit we just set. Let set the grid interval value to 10. The grid Interval will be displayed as the dark grey color on the sketch plane.Then we are going to set the grid unit. The grid unit is shown in the rectangle underneath the 'Snap Bar'. We will change the value by move the mouse over it, the existing grid unit will be highlighted, type in the value of 0.5.We are done with the setting of the grid interval, grid unit and the sketch plane. Let go ahead and save3.
Access the draw functionClick at the pencil icon on the 'Main Tool Bar', and select 'Draw' from the Draw's 'Marking Menu'.Move the mouse into the displayed grid drawing plane, use the mouse scroller, to scale the grid drawing plane to be bigger (easier to draw). Let say, scale the plane up until two or three grid interval fit on the screen.4. Adjust the drawing plane.Use the 'Pan Tool' (Hand icon) on the 'Navigation Bar', to move the Origin point (red dot on the top left corner of the drawing plane) to be in the middle of the screen. (as shown in the image no. 2)You can save the file as the template for later use. Since we are going to use the same setting throughout the project.
Give the name to be something appropriate. The file will be saved as 123D file format (.123d)Notice that when you move the cursor over the drawing plane before starting to draw the first line, there is a message box remind you to 'Specify the first point on the drawing plane and Hold down the Shift Key on the keyboard to lock the sketch plane'.123D app. Want to make sure that you are drawing on the right plane. Especially when, we are starting to draw from the orignal grid line, which have three possible plane to be draw on. The very first model that we are going to work with is the ear, which is easiest of all the four models.Below are the list of the commands we will be using:.
'View Cube'. 'Draw' function in 'Sketch' Marking Menu (or Bucket). 'Revolve' function in the 'Create' Marking Menu to create the 3D model of an ear.Let's get start!1. Rendering of the ear 3D model that we are creating.2.
Cross-section or profile of the eye, with dimension to be drawn in 123D3. Specify the first point at the profile at coordinate (3, 0), by typing the values with keyboard or drag the cursor to coordinate (3, 0) and click the left mouse to confirm.4. Drag the cursor to the left until we get the value 1.5 display in the input data box, or type in the value 1.5 using the keyboard.5. Drag the cursor downward until you get 6mm length to draw the next segment.6. Continue drawing the line to the right perpendicular to the previous line until we get the dimension of 5.5mm.7. Drag the line down to get the distance of 5mm. Then click left mouse button to confirm.8.
Continue to draw the perpendicular line to the previous line to the right with the dimension of 3mm. Click the left mouse to confirm.9. Draw the next line in the upward direction, perpendicular to the previous line, to the dimension of 5mm. Click left mouse button to confirm.10.
Draw perpendicular line to the previous line toward the right to the length of 2mm. Click left mouse button to confirm.11. Draw another perpendicular line upward to the length of 2mm. Click the left mouse to confirm.12.
Connect the line from the last end point to the very first point of the profile. Click left mouse cursor to confirm.13. Now, we got the final profile of the ear.
And we are ready to make this flat profile into 3D model!Before 'Revolve' this profile into 3D model. We need one more reference, a line for the profile to 'Revolve' around to make 3D ear.14. Select 'Draw' pill in the 'Sketch' Marking Menu.
Pick origin point - the red dot, (0, 0), then draw a line downward (align to the grid line) to any length.15. Since we now have the complete ear profile. We could change the name of the sketch to 'ear'. Expand the Sketches Folder, by click at the black triangle in front of Sketch Folder. Highlight the name 'sketch1' and rename it to 'ear'.16. After rename the sketch to 'ear', left click at 'ear' sketch to select the profile.17. Select 'Revolve' pill in the 'Create' Marking Menu.18. 123D will ask you to select the profile(s) or planar face/surface to revolve. Click the 'ear' profile to select.19.
Again 123D will ask you to select the axis of revolution. So, pick the individual line as an axis of revolution.20.
Click at drop down arrow next to keyboard input box, and Select 'Full' function from the list.21. Now, we can see 3D model of an ear. 123D just shows you how it look like. If it is not the way we want we could go back to edit the profile at this stage. Otherwise we need to confirm with 123D that this is OK.22. Right click at the solid 3D model to bring up the Marking Menu. Then left click at 'OK' pill Menu to commit.23.
Now we have the first model! It a good place to save the model before starting the next Step (6). Summary of the commands to use in this Step:. 'View Cube'. 'Move/Rotate/Scale' pill menu. 'Mirror' function in the 'Pattern' Marking Menu. 'New Component' function in the 'Feature Browser' Menu.
'Copy' function in the 'Feature Browser' Menu. 'Paste' function in the 'Feature Browser' Menu. 'Delete' function in the 'Feature Browser' MenuAnd these are the steps:1. In the 'Feature Browser' Menu, turn off the sketch of the ear.2. Set 'View Cube' to TOP plane.3.
Hightlight solid model of ear.4. Right click on the ear model to bring up Marking Menu. Then select 'Move/Rotate/Scale' pill.5. 'Move, Rotate, Scale' Menu show up. Drag the 'Right' direction arrow to the left, or enter value of -14.0 into the keyboard input box.6. Click the Origin Folder in the 'Feature Browser' Menu to 'Unhide' the Origin marker.7. Choose 'mirror' pill from the 'Pattern' Marking Menu.8. After unhide the Origin, we would see the origin of the drawing plane displayed.9. Click at the middle icon in the pill to select mirror plane, Select YZ plane on the Coordinate.10.
Unhide the Origin by uncheck the Origin checkbox, in the 'Feature Browser' Menu.11. 123D will display the mirrored ear on the opposite side of the mirror plane.12. To commit to the mirror command, right click the mouse bottom. Then select 'OK' from the Marking Menu.13. Now, we will connect this two ears together. Let's start to draw the 'Circle' on the 'Right Plane'.14.
Set the center of the circle to -8.5 and 0.15. Assign the radius of the circle as 1.5mm16. Select the circle that we just drawn. Right click at the circle to brign up Marking Menu, then select 'Extrude' pill from the menu.17.
On the 'Extrude' submenu, select the fourth or right most icon on the pill. Then select 'Symmetric'. This will extrude the circle in both direction.18. Drag the bidirectional arrow (or use keyboard input) to 4.5 unit.19. Right click to bring the Marking Menu, then select 'OK' pill to commit the command.20.
Change 'View Cube' to TOP Plane.21. Now we got both ears and an extruded solid circle 'joined' together. And we want to 'Copy' it, and put in in separate folder-'Ear' so it would not included in the solid model we are going to create next (the shoulder).22.
Right click the first item of the 'Feature Browser' Menu. And select 'New Component' from the list.23. Click at 'Solid' to select. Then right click the mouse button to bring up the drop-down list. Select 'Copy' function.24. Select the new component that we just create.
Right click at it, select 'Paste' function from the list.25. Now, the new component has the 'copy' of ear solid model.26.
Rename the new component to 'EAR'.27. Select the original ear solid model on the list. And right click the mouse to bring the list menu. Click at the 'Delete' function to delete the original solid model.28.
Now, the ears model is completed!And it's a good time to save the file. Summary of the commands to use in this step:. 'Sketch Plane' sub menu in 'New Sketch' pill on 'Sketch' Marking Menu. 'Draw' pill function in 'Sketch' Marking Menu.
'Repeat' pill function in 'Sketch' Marking Menu. 'Revolve' function in the 'Create' Marking Menu. 'Snap Menu'. Keyboard Input. Navigating Drawing Screen with Hand Tool and Mouse Scroll (middle) Button.And these are the steps:1. Rendering of the shoulder 3D model that we are creating.2. Cross-section or profile of the shoulder, with dimension to be drawn in 123DContinue working on the same file as in last Step,3.
On the 'Sketch' Marking Menu, select New Sketch pill function.4. Select XZ plane on the Origin Coordinate or 'Front' plane (plane on XZ)5. Set 'View Cube' to the FRONT view.6. The front plane appears with the Origin is on the lower left corner (red dot).7. Right click on the mouse, to drag the drawing plane closer.
Until the Snap value in the Snap Menu display the amount of 0.58. Select 'Draw' pill in t he 'Sketch' Marking Menu9. Set the starting point at 5mm and 0mm.
Then draw the straight line upward at 10mm long.10. And draw a perpendicular line to the previous line by draw the end point to the left, and input the amount of 1.5875mm using the keyboard input.11. Continue to draw the line in upward direction, using the keyboard input to enter 12.7 for the length of line.12. Drag the endpoint of line in the Y direction (toward the right), and enter the length of the line as 11.2mm.13. Drag the next endpoint downward, and enter 12.7mm for the length of the line.14.
Drag the next endpoint toward -X direction (to the right), and enter the value of 6.6125 for the length.15. Drag the next endpoint of the line toward -Y direction (downward) and enter 10 for the length of the line.16.
Then join the next end point to the start point of the profile.17. We now got the cross-section of the shoulder. Next, we will revolve the profile to create solid model.18. Before we could 'Revolve' the profile, we need to draw the revolving axis first. Select 'Repeat.' Pill on the 'Sketch' Marking Menu.19. Set the starting point of the line at the position of 11.1125 and 10, by using the keyboard entry.20. Drag the endpoint of the line upward.
And enter the length of the to any amount you preferred.21. We are done with the shoulder profile. And ready to make a 'revolve' the profile to make solid model. It a good time to save the file now.22.
Use 'View Cube' to set to 'Home' view.23. Use 'Pan' function from 'Navigation' Tool Menu to reposition the drawing in the middle of the screen.24. Use mouse 'Scroll' wheel (middle mouse button) to scroll drawing closer.25. Select 'Revolve' pill from 'Create' Marking Menu.26. Select the profile when 123D asks for it, and select the axis of revolution. (Note: We did this command before in creating ear steps.)27.
Click at drop down arrow next to keyboard input box, and Select 'Full' function from the list.28. Right click mouse buttom to bring up Marking Menu. Then click 'OK' to commit the command.29. Here we are, the incomplete shoulder. We are going to do some more editing to complete the shoulder solid model.
Save the file! Create 'New Component'- Add solid model to a browser as Left Shoulder- Make a copy of a shoulder add a solid model to a browser2. Select 'Fillet' pill in the 'Create' Marking Menu.3.
Select the top edge of the solid model.4. Specify the fillet radius, by drag the bi-direction arrow or use keyboard input to the amount of 11.25. Select 'TOP' View on the 'View Cube'6. Right click at shoulder solid model to bring up the Marking Menu. Then select 'Move/Rotate/Scale' pill.7. Drag the the Right arrow to -14, or enter -14 in the input box.8.
Set the 'View Cube' to Home.9. Unhide the Coordinate Origin.10. Right click at the solid model to bring up the Marking Menu.
Then select 'Mirror' in the 'Solid Features' list.11. Select YZ Plane on the Coordinate Origin to 'Mirror' the shoulder.12. Right click the mouse to bring up Marking Menu, and select 'OK' to commit the command.13. Now we got he complete left and right shoulders!14. Start to draw the 'Circle' on the 'Right Plane', using the 'Circle' pill from the 'Sketch' Marking Menu.15. Set the center of the circle to -14 and -5.16. Assign the radius of the circle as 1.5mm17.
Select the circle that we just drawn. Right click at the circle to brign up Marking Menu, then select 'Extrude' pill from the menu.18. On the 'Extrude' submenu, select the fourth or right most icon on the pill. Then select 'Symmetric'. This will extrude the circle in both direction.19. Drag the bidirectional arrow (or use keyboard input) to 4.5 unit.20. Right click to bring the Marking Menu, then select 'OK' pill to commit the command.21.
Change 'View Cube' to TOP Plane.22. Right click the mouse to bring up the 'Move/Rotate/Scale' Marking Menu. Then drag the up arrow to move the cylinder to approximately middle of the shoulder.23.
Rotate the 'View Cube' to view the FRONT view.24. Select the Solid model of shoulder component.25. Right click on the shoulder solid model to bring up Marking Menu. Then select 'Combine' from the list.26. Select the cylinder, to combine to shoulder solid model.27. Right click mouse to bring up Marking Menu, Then Click 'OK' to commit command.28.
Now we got both shoulders and an extruded solid circle 'joined' together.29. Rename the 'Component' to 'Shoulder'After you're done with the shoulders, save the file.And always save the file often, this can prevent you from starting over from scratch!
Further Study. My guess was, we were already tired of starting to create an objects with 'Draw' function in the 'Sketch' Marking Menu (bucket) to draw lines already!!Alright, we are going to create 3D model of hands and fingers using different approach. This time we are going to create hand with four fingers, without going through the the process of lines drawing any more.
A lot more fun! And we are going to do this in the 'Orthogonal View' alone. No swapping view around either!Let's plan ahead of how we are going to create an hand, using the available cross-section.On the cross-section sketch sheet, we can only see that there is a profile of the finger. With no locations or coordinates of any finger found. That is not the problem, because I have the information of these four (Yes, four. Because It's the robot!) fingers as follow: Thumb. Height 6mm, radius 1.5mm, location -7.6, 1.5 (Top Plane X,Y coordinate)Also the cross-section of the hand indicates that there are three circle with the radius of 8.1125 (The void area inside the hand), the OD (Outside Diameter) circle with the radius of 12.7mm, and the ID (Inside Diameter) circle of the hand has the radius of 11.1125mm.
Are adequate to build the hand.We are going to create all the fingers on the top plane first. Using 'Cylinder' function in the 'Primitive' Marking Menu or bucket.Then 'Extrude' them up to their height. And 'Fillet' the top end of those fingers.Next, we will use 'Create' tool in Main Tool Bar to create two 'Cylinder' and assign the thickness of the palm and wrist.Then use the 'Shell' function in the 'Create' bucket to create the void area in the wrist.Add use ' Combine' function in the 'Create' bucket to combine all the fingers, palm and wrist together as one single hand.Make a copy of hand and add a solid model to a browser.And these are the steps:1. Rendering of the hand 3D model that we are creating.2. Cross-section of the hand, with dimension to be drawn in 123D.3. To draw the thumb, select 'Cylinder' pill in the 'Primitive' Marking Menu4.
Set center point of the cylinder at 7.4 and 1.25. Assign the radius of the circle as 2mm.6. Drag the bi-directional arrow up to specify the height of the thumb as 6.45mm7.
Right click the mouse to bring up the Marking Menu, then select 'Repeat.' Pill to draw the new cylinder, the First finger.8. Set the center point of the cylinder to 2.5 and 2.759. Specify the radius of the First finger to 1.5mm10. Drag the bi-directional arrow to set the height of the First finger to 8mm11. The command again to draw the new cylinder, the Second finger.12. Set the center point of the cylinder to -2.7 and 2.7513. Set the radius to 1.5mm14. Drag the bi-directional arrow up to specify the height of the thumb as 7.5mm15. 'Repeat.'
The command again to draw the new cylinder, the Third finger.16. Set the center point of the cylinder to -7.6 and 1.517. Set the radius to 1.5mm18. Drag the bi-directional arrow up to specify the height of the thumb as 6mm19. These are the new components for the fingers.20. Next we are going to 'Fillet' the fingers to have the round ends.
Select the 'Fillet' pill from the 'Create' Marking Menu21. Select the top edge of the Thumb.22. Drag the bi-directional arrow to specify the fillet radius to 2mm23.
Right click to bring up Marking Menu, then select 'OK' pill to commit the command.24. Right click to bring up Marking Menu, then select 'Repeat.' Pill to 'fillet' all the rest of the finger.25.
Select the top edge of the First, Second and Third fingers.Then specify the fillet radius to 1.5mm, either by dragging the bi-directional arrow, or input the value using keyboard.26. Commit the command by right click the mouse and select 'OK'27. Now we got the fingers done! Further Study.
