jolizon590016 Posted September 5, 2019 Share Posted September 5, 2019 Here is a challenge open for everybody. The measurement in red is the correction as I earlier missed out on the calibration on the Inventor viewer I have done the 3D wire from a polygon shape set as pentagon and decagon. I got stuck on the sweep. challengeA.ics 1 Quote Link to comment Share on other sites More sharing options...
BSTAFF Posted September 5, 2019 Share Posted September 5, 2019 From what i could tell, there is no great way of creating a single sweep from the wire-frame, but by separating the 3d wire, i was able to come up with the shape.

BSTAFF Posted September 5, 2019 Share Posted September 5, 2019 Also this is a Regular Icosahedron, so you could just use 3 orthogonal golden rectangles to easily model the shape. See attached. https://en.wikipedia.org/wiki/Regular_icosahedron d20.ics Quote Link to comment Share on other sites More sharing options...
jolizon590016 Posted September 5, 2019 Author Share Posted September 5, 2019 Thank you very much Blake. If you can post your work to the TFI challenge will be greatly appreciated.

SVAN GELDERN Posted September 5, 2019 Share Posted September 5, 2019 This was fun! My approach was to look at it like I actually had to build it. (2) custom joints and a single spar. Calculated Mass: 2.3744 g Calculated volume: 2198.5373 mm Steve vGm_Invusion_002.ics 1 Quote Link to comment Share on other sites More sharing options...
AMEHRAEEN Posted September 7, 2019 Share Posted September 7, 2019 Hello I think its better connect bars to a sphere in center of all joints specially those are complex or crowded. it's more beautiful and looks stronger and easier to make. 2 Quote Link to comment Share on other sites More sharing options...

SVAN GELDERN Posted September 9, 2019 Share Posted September 9, 2019 jolizon590016, Looks good. Double check your density. The .ICS above uses 1.07 g/cm3 I think the challenge specified 1.06 g/cm3 Steve 1 Quote Link to comment Share on other sites More sharing options...

jolizon590016 Posted September 9, 2019 Author Share Posted September 9, 2019 (edited) Hi Steve, The image text is close together that 1060 or 1080, so I just used the IC material ABS PC 1070 rather than ABS 1020 on the list. Thanks for joining in and to the rest of the users regards joseph Edited September 9, 2019 by jolizon590016 Quote Link to comment Share on other sites More sharing options...
