How would you create this shape in Autocad?

Anonymous — Sat, 06 Jan 2018 01:35:21 GMT

It's kind of hard to describe, but I'll try my best. Start off with a standard trapezoid (the one where the short side is on top of and in between the longer side). The two obtuse angles of the trapezoid have then been rounded off with a fillet. (The resulting shape will look kind of like what you would see for a headrest on a car seat.) I've encountered this shape on an object that I'm trying to model, and I have no idea how to start it.

a picture would be much easier to understand.

why not draw the trapezoid, then fillet the corners with a specified radius?

Hi @Anonymous,

I would start with drawing the top and bottom edges. Then create the short angled side. Next fillet the edge with the top and bottom. Last, you can mirror the edge and fillet corners.

If you then want 3D, use PressPull to give this outline some thickness. If you want want to curve the edges you can then apply a FILLETEDGE.

Does this help or do you need something totally different?

Hi @Anonymous

Did I get close to what you were looking for? Can you give more detail to help you with this question on creating the shape?
