Closed sweep alternative/workaround?

[Dirk77]

Hi All,

I've searched and tested some other instances on the forum but nothing changed the result. I want to create face-based family of a sink that can be adjusted to specific sizes. I'm trying to model a parametric sink, but the closed (and open, I tried) sweep fails to generate. One alternative is to just model 15 different sink sizes and allow users to pick them, but I want to cut out such input and file sizing. Ideally, the result would be 1 sink of 3 or so elements at most if doable, and parametric in depth, width and height.

The top 2 views are my base for 1 sink. The current sweep is cut 1mm short from the bottom to avoid a square interior perimeter (which causes the sweep to fail to generate), but applying parametric dimensions to this is causing constraint issues.

Bottom 2 views are the easy way out, but I'd like to avoid the many user options and file size this creates.

Any ideas or alternative suggestions?

Self intersecting sweep issue?

You could try a 90 degree revolve at each corner, with a sweep or extrusion at each side and a rectangular extrusion at the base, all joined to create one nice monolithic lump of sink.

What code are you using so far?

How exactly does it fail to generate?

I think this is not an API question is it?

I've attached a file with construction as I noted above. I would probably just nest it if you wanted it face based.

I'll give this one a try. I've been avoiding too many parts in concern for constraints issues, but nesting it may just work fine. Thanks

Thank you for sharing. Unfortunately I'm limited to version 2021 currently, but I get the gist of your suggestion.
