Hi,
My name is Petar Perisin, And I'm trying to connect FreeCAD and
pythonOCC. I have posted 2 messages on web site, so here they go:
Hi,
I have been playing with this STEP export. I have also found
pythonocc-examples project on code.google.com (you should also
include this google code project on your web site, because there is
no link to it here -- I have found the link on google). Over here
there is test_XDE.py and the program creates some moduels, colors
them and exports STEP with colors. Couple of questions:
1. Over there there StepOCAF_Export class (from the
Utils.DataExchange package) is not used. It Uses STEPCAFControl
writer. Is this the same thing (it confuses me a little bit) or am I
wrong?
2. I know that you were talking about how StepOCAF supports layers
and colors. This layers is what I'm interested in. Are this accually
'Parts' that appear after I import Step file into another program,
so I can see that Step is accually made from many parts
(XDE_test.step has three parts -- 2 boxes and a cylinder)?
3. Code does not seem to work untill you comment lines from 69-79
(and, of course, uncomment lines 83-86). He reports error on line 74
-- "Attribute Error: 'TColStd_ListIteratorOfListOfInteger' object
has no attribute 'Value' ". It is probably connected to line 72,
where this is assigned. How to fix this (in other way than comment
lines from 69 to 79)
4. I have been looking through the code (newbie look) and I have
figured where new document is created, where shapes are created,
where components are referenced in assembly and coloured after that.
But, as hard as I try I can not figure out what do lines 69-79 do?
What do they do?
5. Is there a way to assign colors based on Red-Green-Blue values
(this was not used here) and if yes, what is the range for this
values (is it 0-1 float values like in FreeCAD or is it 0-256
integer values) -- can you give me an example of this?
Thank you very much for pythonOCC
And the second one is:
Hi,
I wanted to explain what am I doing. I'm trying to export complex
shapes from FreeCAD to STEP with colors using pythonOCC. So far I
have managed to do that with simple shapes like sphere, box, cone
ect. But how to export cut between sphere and a box. I saw another
example test_cut.py, and from there I took and modified a few things:
from OCC import BRepPrimAPI, BRepBuilderAPI, gp, Geom, STEPControl,\
BRepAlgoAPI
R = 20.
sphere = BRepPrimAPI.BRepPrimAPI_MakeSphere(R)
box = BRepPrimAPI.BRepPrimAPI_MakeBox(100,100,100)
cut = BRepAlgoAPI.BRepAlgoAPI_Cut(box.Shape(), sphere.Shape())
now, how to export 'cut' as STEP with color. He reports some error
that 'cut' is of different type. How to make 'cut' be good type?
