Stitching Styling Features
Stitching Styling Features
(OP)
I'm a Catia v5 user trying to pick up some UG. We're using Catia v5r16 and UG NX3.
One feature I'm trying to find (and I'm sure UG has it somewhere) is the ability to sew in e.g a styling blend fillet into the existing solid. The reason is that styling surfaces are not allowed to change and the fillet curvature is smaller than the thickness.
In v5 I would join the blend and trim the boundaries exactly to the solid and then use the function Sew (without intersection) and if the blend is perfect (which it usually is because it's a-class) it will insert the blend into the solid. On the B-side I would just put in a normal radius.
I do have the docs and I have done the cast training but haven't found any specific examples of this nature.
Any help is appreciated.

When using Patch, you have to completely enclose a volume (with part of the solid and the surfaces you wish to add) and have no holes/gaps between the surfaces and the solid. See the Documentation for a better understanding...difficult for me to explain it without visual references.

The documentation explains how to use Patch quite well. Without having your part on hand, it's difficult to know for sure why the blend surfaces wouldn't work without making them solid.

It was definetly worth a star thanks again Tim.

Good deal. Patch can be a very powerful tool for adding complex surfaces to an existing solid.

Sometimes Trim Body doesn't work when you have surface edges that lie exactly on the solid (non-manifold condition or tangency, etc.), so Patch is what I fall back on in this case. It can be a big time saver if you're stuck with trying to insert complex surfaces into a completed model.
In another situation, where you're adding volume rather than removing it, I'd say Patch is about the only thing that might work, without making the added surfaces into solids and Sewing (solids) or Uniting, which is just more mouse clicks.

In Catia v4 and v5 when you use Patch (it's called sewing in Catia)it ensures that you keep tangency and curvature conditions intact but if you use a trim or subtract operation you might be able to remove the material but it could destroy the tangency-curvature condition hence that's why when doing the sewing the boundaries must lie exactly on the solid.
I suppose UG works in a similar way.
