Re: STEP 242

Thank you for the link. This will help me. I want to read the step files and store the information in a graph database. I use neo4j. With the stored data I can get the geometry data to create edges, faces etc. But it can be used for topological investigations too. The workflow is: read and parse th...

I mean the other problem zone can done also with an exact straight transition with fillets.
That looks close to picture, which is all you can do without proper dimensions. Nice.

Re: Fillets and old iron

But, the fillets are not as specified either... .118 vs. .125 Yup, I missed that. One interesting thing is the use of pads for the flange instead of a revolve. Which appears to allow the engine to handle fillets somewhat better. Can you determine the type of surface output by the revolve? 'planar' ...

Re: Fillets and old iron

Just for testing. Works without problems here (PartDesign). But i was expecting errors on the corner (like other CADs) so i the way i model it was a little different (like i do when i see corners like that). Oh sure, just move the base chamfer away from the problem area ;) It is not specified on th...

Wow ! Looks nicely done - can you post the file?
I used opencascade, but not freecad. So all I can give you is a brep. If you want to know how I did something specific, just ask.

Re: Fillets and old iron

opencascade can do it with the proper amount of swearing. I had the most trouble in the front area without the boss.

The original STEP file as provided by Newport works flawlessly, but the one that came with the assembly doesn't.
Can you post or provide a link to the problematic step file?

Re: Utility to inspect OpenCascade models

I'm on Mint 19.3 which is based on Ubuntu 18.04 LTS... ATM I'm stacked on detecting OCCT: What version of occt? Where is it installed? What are your results of these 3 commands? cmake --find-package -DNAME=OpenCASCADE -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST cmake --find-package -DNAME=OpenCAS...

Re: Utility to inspect OpenCascade models

Out of curiosity what are the issues you have with cmake and what's better with meson? This is pretty subjective, so I will list what I can come up with right now but you should just try it on something. I have used meson on linux and mac, but can't speak to the windows experience. This is my prior...
