i’d like to make a rod or post of square cross-section, twisted. i made the attached with extrude, then twisting the top, then duplicated it vertically. it becomes thinner toward the center of the pieces. is there a way to make one if uniformly square cross-section? thanks! [IMG_1111]

Have a look here… [image] New to app, having some trouble Need help? We are here. Is it possible to twist a shape so as to achieve this effect? When I try,it just twists over itself in the middle then unwinds. [image]

thanks, good ideas. i tried the loft trick before i read this and didn’t think it worked but maybe it did. thanks!

Yes, I encountered the exact same problem you did. Then I realized that Loft was the way to go. -Mike

i measured the lofted one and on a 2cm square, 45 degree loft, the center square is about 1.8cm close, but not perfect. [IMG_1112]

If you twist 90degrees you will see that cross section area will be half as vertical edges are kept straight

right. If the area were constant, the edges would form a helix. Smaller rotations and shorter steps will get us closer to that, but I see no direct way of forming a uniform-thickness twist. Which is OK, I wound up not liking the look of it for what I’m doing anyway. :slight_smile:
