STEP Import Assistance (SolidEdge?)

Hi gang,

I’ve downloaded a vendor model (only available as a STEP file) and it’s coming in not particularly cleanly in to SW23. 3DInterconnect on/off produces slightly different results but neither are that great.

Before I launch in to cleaning up the model, could someone with access to software other than SW take a look and see if it imports cleaner there please? Then maybe try a Parasolid translate to see if that’s a better output?

Any assistance gratefully appreciated.

What do you expect? It’s not that bad. SW2023 SP2.1

I’d anticipate more of the internal geometry / geometry under the cap being available to inspect. Just trying to get a feel for if the part was butchered before it left whatever software it came from, or if the import is losing a whole bunch of faces / shapes inside the part.

Looking at the STEP file, it was exported from SolidWorks 2021. Maybe some of the parts themselves were imported in that version when the vendor was building it in 2021. Missing thread faces are typical when importing models from something like CATIA which has loose model tolerances. I suspect CATIA because there is a hole in that end piece on the left that has two half cylinder faces and I remember CATIA doing that everytime.

For reference, I attached 2 images, one using Mayo and other SolidEdge2024 CE.

I also opened STEP file in NIST’s ‘STEP analyzer’, and it does find some issues with it, non-conforming to AP203, AFAICT.

Okay, thanks gang. I guess this import is as good as it’s going to get without some time investment then.

Thank you for the mention of Mayo.

That looks really cool, I need to try it out.

Cheers

@doobes I forgot to link to it, sorry :slight_smile:

Mayo

It’s pretty nice, open source and free.

There are some UI annoyances, TBH, but nothing major, IMHO.

That looks beautiful, I wish it could open native files such as SolidWorks files. eDrawings would go out the door so quickly if it did.

Thanks,

It wasn’t hard to find.

Another resource of this type is: CAD Assistant.

I’m always looking for robust file converters.

Yeah, CAD Assistant is nice too.

Both Mayo and CAD Assistant use opencascade kernel, so file type support should be

similar between the two.

@AlexLachance There is a survey at CAD Assistant page, and one of the things they ask about is if support for Solidworks files is needed.

AFAIK, they plan, if enough people/companies are interested, I guess, to offer

‘business edition’ of it, with support for various proprietary file formats via (paid for) plugins.
