Hi, I’m trying to make a cuff with a hinge closure, but for some reason I’m not able to split the main object with my hinge-shaped polysurface.Cuff.3dm (3.1 MB)
I’ve tried pretty much everything, but I know there’s something I’m doing wrong.
Very new to rhino, been using it for about 2 months now.
Thanks,
V
Hi Valentina. The hinge won’t split the cuff because it does not separate it into two pieces. If your next step was to split the result with the line in the model, just pick both the hinge and the line as the splitters in a single call to split. You’ll have to pick the line in either the top or perspective viewports so Rhino knows which way to project it.
I guess that in the real world, you will have 2 halves and a hinge, right? In your model, you are only making a cut into one side of the ring - when you do that in the real world, that ring will still be one solid with a fracture on one side.
Consider this picture
Your top and bottom of our main object is basically a square piece with two circular cuts - like the object on the right in the picture. When you try to make a cut with the blue line, the thing will still hang together.
If you make your geometry by revolving a line around a center point, you will end up with geometry like on the left side in the picture. If you now use the same blue line, the surface will split because there already is an edge in there.
Hi @MVCV25
because your hinge-shaped polysurface has no thickness the cuff cannot be splitted. One way is to make a plane on the opposite site and split the cuff with the 2 surfaces. see pic.
Other way is to give the hinge-shape some thickness with offsetsrf and a thickness of maybe .001
Perfect! Got it to work!
Thank you so much!
