STEP model becomes surfaces

From time to time we get step files from customers or clients. If we want to use them in our assemblies, we save them as a SOLID EDGE part or assembly. After the conversion, only surfaces remain. Is it possible to have a solid instead?

 

If we use the surface models in our drawing, some extra, unwanted actions are needed to properly display the component - we want to avoid that.

Have a look at your import options - make sure you have the stitch option selected.

If you don't get solids with this set, then there could be a problem with the data being imported.

You could also try changing the stitch tolerance value.

Johan, it depends on the step file. If it is a valid Body, or faces that SE can stitch together to make a body then you're in luck. If it's just a collection of non-manifold surfaces then SE can only treat them as constructions.

Just make sure that if you do have bodies, that they're design bodies and therefore show in drafts by default, and not construction bodies which don't. It's easy to toggle them between the two states.

Thx,

 

We can choose between Heal&Stich & Stitch Surface, but none of them result in a solid body.

Is there a setting to make the stich gap wider (more tolerance)?

I was sure there was a tolerance setting, but I can't see it anywhere.

Have you tried the 'use beta step translator' option ?

Other than that, its what @Alex_H said - if the surfaces don't match up then they won't stitch together.

What system have the step files come from ?

Hi,



have You tried to heal the suraces after import using the healing function?

 

There - as I remember - the tolerance could be defined.

@beachcomber I think the tolerance setting you remember is under the manual stitch command in the surfacing tools.

Yes, I think you are correct.

Hi @Johan,

 

Do you have an example problematic STEP file you could share?

I have had files like that. Sometimes the best thing is to ask for new exports from the supplier of the file while also letting them know what the problems are you are having with the file. If schedule does not let you do this, sometimes re-modeling using the existing surfaces as dimension reference is the way to go. But then you are spending your time vs. just getting the right file.
