Use any line/curve/edge in extrude

Dean_GardnerDean_Gardner Member Posts: 88 PRO
So I have been spoilt in a previous package where i could use any line/edge from a solid, curve, or sketch to extrude from.  It didn't have to be plainar either.  Is this a possibility in Onshape? It seems that i can only create an extrude from a face or sketched line.

    Hi Dean, to extrude you would need to sketch something. I'm not sure how you would extrude from an edge, how would you define a sketch without a plane to sketch on? Maybe I've misunderstood the question.

    @leecasey in NX i could pick the edge of one of those holes to create a round bar extrude.  Extrude doesn't let me select it, unless i sketch over the top of said hole.

    I could even click around the perimeter of this pocket (below) and create a surface that would radiate out in a single direction.

    Ah I understand now. I know you can re-use sketches, so if that hole was created from a sketch you can just unhide the sketch and extrude from that.

    There's a custom feature (though not created by us at Onshape) that does this: https://cad.onshape.com/documents/24819ddab7dc83c810eb8246/v/b409220bda82b907cd49f383/e/38727ba0d05188ebe79387a5

    Just be aware that it was a fork from the standard Extrude feature code of a few years ago, and has not kept up with the latest and greatest (especially a few things from this year!).

    I would be interested in expanding the native one in this direction a bit more. It seems like it's moving that way now that a direction can be selected. I know opExtrude() isn't limited to planar inputs.
