How to Make "Concentric" Bezier Shapes?

bill_donnelly

Hi, is there a way to make 'concentric' bezier enclosed shapes?

I'm trying to make a heart-shaped picture frame, the basic shape is easy, but creating 'concentric' shapes in the sketch so that I can extrude the face of the frame, then the walls at a different height, then a base that fits in the rear.

Once I create the shape I need, is there a way to copy/duplicate it exactly but with different dimensions?

Hope this makes sense - basically I want to draw an enclosed bezier shape, then copy that shape 10mm larger.

thnx

Try offset face and move boundary.

You can also sweep whatever profile you want along with your heart-shape as the path. Here's a public doc with an example of this.

Within a sketch, you can just offset a curve. You can also copy a curve and scale it. Scaling will not be the same as offsetting, except in simple cases like a circle or other regular shape.

I voted for S1mons example. Much simpler.
I've been working with warped surfaces that makes my example more useful where a sweep just won't do. Just what I was thinking at the time.

Thnx guys, fantastic advice, love the different options. Still pretty new to onshape (~3mo), love the flexibility . . . once you know how ;-)
