Have an Openscad to Freecad conundrum to solve [solved]

KeithS, next time you can direct folks to just read the wiki About page

Except if they are on a Mac as the wiki does not correctly explain for a Mac

My fault.
I haven't pasted the entire information from FC. I wrongly assumed that judging by the number of posts disclosing version, people following this post would know. No one knows what happened in between.

I will try to post detailed information about those details. That aside, I tried to post a well-explained issue, yet, in a concise manner. Would there be anything else you would like to have?

OS: Windows 10 Version 2004
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.24291 (Git)
Build type: Release
Branch: releases/FreeCAD-0-19
Hash: 7b5e18a0759de778b74d3a5c17eba9cb815035ac
Python version: 3.8.6+
Qt version: 5.15.2
Coin version: 4.0.1
OCC version: 7.5.0
Locale: English/Canada (en_CA)

And the OCCT
My library tab says:

Open CASCADE Technology 7.5.0

My importCSG.py is possibly the latest developed by chennes.

Oh yeah! Thanks for pointing that out. I'll add it to the wiki ASAIC.

My understanding is that OCCT 7.5.0 has the regression see https://forum.freecadweb.org/viewtopic. ... 97#p502797

From the post you sent me to OCC 7.5.0 not good.

My occt says that she is 7.5.0

Thus my job now is to upload a FC version having proper occt.

A later than 0.192 version is my best guess if there is one later than 0.192.
So I will try to do something like that. Sounds good?

What version of OCCT are you on? I think there is a step export bug in 7.5.1, I wonder if this is hitting that.

Points out to occ 7.5.1 as the one having the problem.
The post from keith points to 7.5.0 as the one with the issue.

I presume that chennes was just wrong.

I don't think Chris is wrong. Not sure when exactly the regression occurred, but according to https://tracker.freecadweb.org/view.php?id=4610 it is still present in 7.5.1 and fixed in 7.5.2.

I would try FreeCAD 0.19.1 my install has OCC 7.4.0 and is pre the regression which occurred some time between 7.4.0 and 7.5.0

It is important to note at this point that:

OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 32-bit
Version: 0.18.4 (GitTag)
Build type: Release
Branch: releases/FreeCAD-0-18
Hash: 980bf9060e28555fecd9e3462f68ca74007b70f8
Python version: 2.7.14
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.2.0
Locale: English/Canada (en_CA)

does import the simple boolean prism (base) correctly and allows its proper use in later booleans. I believe this may be important: one, because whatever is happening is limiting 0.192 to conduct this simple boolean itself and two, because I'm having issues conducting booleans in 0.192 in which I build a solid of 2 components which is then subtracted another solid of 2 components with asterisks in the tree. I don't expect an answer to issue number 2 because I'm not providing enough information, however, you may have enough information for issue one which may in the end solve issue 2.

Another important thing to note is that:

OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 32-bit
Version: 0.18.4 (GitTag)
Build type: Release
Branch: releases/FreeCAD-0-18
Hash: 980bf9060e28555fecd9e3462f68ca74007b70f8
Python version: 2.7.14
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.2.0
Locale: English/Canada (en_CA)

does produce a good step file, instead of the step file with defects presented in this post. It is thus somewhat precise to point the OCC 7.5.0 an/or the 7.5.1 as liable for faulty steps in this post.
