Hello Dave, hello all,
(1) In the 'old' build system, there were one pyd file for each set of
classes TopAb, TopExp, Geom etc. The whole project was structured in a better
way than now: all in only 2 files: OCC.py and _OCC.pyd (for Windows).As a
consequence you just hve to do "from OCC import *" in order to have access to
classes.
(3b) TopAbs_Shape enum in the name of the enum. It's a 'category' of available
options. In the SWIG file, it is defined as:
enum TopAbs_ShapeEnum {
TopAbs_COMPOUND,
TopAbs_COMPSOLID,
TopAbs_SOLID,
TopAbs_SHELL,
TopAbs_FACE,
TopAbs_WIRE,
TopAbs_EDGE,
TopAbs_VERTEX,
TopAbs_SHAPE,
};
So when the parameter TopAbs_ShapeEnum appears in a function prototype, you can
use any of the 9 items of the category. I agree with you: it's not clear at all!
(2) Installation of release 0.97 will replace the old one.
Regards,
Thomas Paviot

Objet : Re: [Minerva-pythonocc] pythonOCC 0.96 and STEP import bug
Hi, Thomas/All:
I have downloaded and installed pyocc v 0.96. My observations:
(1) The documentation is much much better, and most of the structure is much
better organized. IE, it is better to do STEP_Control_Reader() vs
STEP_Control.STEP_Control_Reader()! Kudos, Thomas, to you on the new layout
and new documentation!
(2) The constructor bug I had with TopExp_Explorer seems to be fixed.
(3) There are a couple of libraries/objects Im using that appear missing in the
new distribution:
(3a) -- BRepBnd seems to be gone-- it used to be there?
(3b) -- TopExp_Explorere references TopAbs_ShapeEnum, but this enumeration
does not exist. To test that TopExp_Explorer works, I foundt the values via
the constants from OCC, and it worked perfectly. In previous version, you could
do TopAbs_FACE.
(4) Just a note to those who might upgrade, running the installer for version
0.96 will _not_ automatically remove the older version-- you need to remove the
old version from lib/site-packages manually... Evidenty the older version will
take precedence by default.
Thomas, thanks for your work, and let me know if I can help out!

Hello,
Dave Cowden submitted in a previous post a bug in step file import. Latest
release of pythonOCC fixes this bug.
Here are the results obtained from the import of a 44.4Mb step file (an
aircraft) by using the script "STEP_import.py" available on pythonocc home page:
