Hello, I'm new to MOI and having fun!

 MOI has really made modelling much more fun for me. I'm an artist and creating 3D objects for some stories I'm telling. I can't believe how easily and quickly I can make things. I did this U-joint with no difficulties. I find myself using MOI to solve self-imposed puzzles even when I don't really need to be making things at the moment. Thanks! Image Attachments:

 5610.3 In reply to 5610.1 Got the coincident cylinders without even asking! Could you describe what your process was? Thanks.

 5610.4 In reply to 5610.3 Hopefully this will make sense: 1. Start with 2 circles extruded into a cylinder. 2. From the front view create 2 equal ovals to extrude and cut out the sides creating the classic U-joint shape (Boolean Diff) 3. Don't forget to cut the hole using Boolean Diff as well. 4. Finish by running Fillet on edges you want rounded. You should have something similar to the *second image. 5. From the Front view, copy the shape in place. 6. With the original still selected, use the Rotate command. Select the center of the hole from the Front view and rotate the object until it is vertically opposite the second piece - the holes will still be lined up at this point. 7. With the original still selected, use the Rotate command again but this time from the Top view. Rotate the object 1/4 turn. You should have something similar to the *first image. The center 4-way connecting rod can now be made by creating a new cylinder fit to one of the holes, copied and rotated, then connected via Boolean Union. Run fillet on intersections between the cylinders to smooth them out. Hope that makes sense. Let me know if you want/need more info. EDITED: 22 Dec 2012 by SCOTTH Image Attachments:

 5610.6 In reply to 5610.5 Hey al, nice results! What did you texture/render this in to get the slightly worn edges? Very cool.
