Re: [Pythonocc-users] STEP and Geom

Occ.dataexchange.utils offers a nice shortcut, file_to_shape and shape_to_file 
provide nice short hands for writing to Brep, stl IGES and step files, and 
reading from these files.

   Well, just changing the case and it worked properly too! Here are the 
lines added/modified, so you can check if we did the right thing:

from OCC.TopoDS import TopoDS_face
(...)
stepnurbs = Geom_BSplineSurface(stepptosctrl, steppesos, stepuknots, 
stepvknots, stepumults, stepvmults, k-1, l-1, 0, 0)
stepnurbs = TopoDS_face(BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-

stepwriter = STEPControl_Writer()
stepwriter.Transfer(stepnurbs, STEPControl_AsIs)
stepwriter.Write(arquivosaida)

TopoDS_face(...

Note the lower-case "face".  Can you try it and confirm you no longer get an

After analyzing the OCC documentation, BRepBuilderAPI_MakeFace returns a 
TopoDS_Face.  Therefore, my original directions to convert with TopoDS_face

   Well, I did what you said, except the command TopoDS_Face, as below

   stepnurbs = Geom_BSplineSurface(stepptosctrl, steppesos, stepuknots, 
stepvknots, stepumults, stepvmults, k-1, l-1, 0, 0)
   stepnurbs = BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-6).Shape()
   stepwriter = STEPControl_Writer()
   stepwriter.Transfer(stepnurbs, STEPControl_AsIs)
   stepwriter.Write(arquivosaida)

and it worked. The STEP file was written, I opened it on IDA Step and 
Rhinoceros and they read the file correctly. So my last question is: 
omitting the TopoDS_Face command "harm" my code in any way?

Hi Dalton,

Does python tell you which line it doesn't like?

>From the TypeError, it seems like it would be this line:

steptopo = TopoDS_Face(BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-
6).Shape())

If so, try breaking the line into parts:

brep = BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-6).Shape()
steptopo = TopoDS_Face(brep)

I would imagine the error would then be on the second of these lines.  If so, 
try displaying brep with the simpleGUI to make sure it looks like a face (a 
surface bounded by a wire).  If the display doesn't look right, there's 
something wrong with your surface.

Let me know what you find, and we'll go from there.

   What you said is exactly what I do, I just copy the lines wrongly here, 
sorry. So, this is the part of my code supposed to write the STEP file

   stepnurbs = Geom_BSplineSurface(stepptosctrl, steppesos, stepuknots, 
stepvknots, stepumults, stepvmults, k-1, l-1, 0, 0)
   steptopo = TopoDS_Face(BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-

   stepcontroller.Init()
   stepwriter = STEPControl_Writer()
   stepwriter.Transfer(steptopo, STEPControl_AsIs)
   stepwriter.Write(arquivosaida)

and the error for running it

Hi Dalton,

Is arquivosaida the name of the file?  It should be.

What is steptopo?  I don't see it defined in your example code.

If this is exactly what you're running, try changing this:

TopoDS_Face(BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(), 1e-
 6).Shape())

to this:

steptopo = TopoDS_Face(BRepBuilderAPI_MakeFace(stepnurbs.GetHandle(),

   I had already done almost everything you told me before you wrote. But, 
even with the "add-ons", I still can't get it to work.

   The piece of my code that is intend to write the STEP file is below. I 
tried to explain/comment at most, to make it as clear as possible.

for i in range(0,p):

   Even then, I get the error

are experient it may be easy. :)

Hi Dalton,

Sorry my github example wasn't clear.  I'm not sure exactly what you sent to 
TopoDS_face and BRepBuilderAPI_MakeFace, but I got it to work.  I
used the BSplineSurface in src/examples/Geometry/geometry_demos.py and
successfully wrote a STEP file.  My changes have a #CSS comment nearby.
See below, particularly the topodsface line.

I suspect you didn't use the .GetHandle() method or the .Shape() method,
but I can't be sure without seeing your code.

   Hi, Damir, thanks for the reply and the help!

   I've tried to use these command lines you mentioned, from the example 
files, but without success. STEPExporter asks a Topo object, I guess, and I 
am working with a Geom object.

   I am, now, trying to translate my Geom_BSplineSurface into a TopoDS_Face. 
Hope this is the right way.

Hi Dalton,



you could try to change the line "stepexporter.Write(arquivosaida)" to 
"stepexporter.Write(arquivosaida.Shape())", I hope it helps.




Best regards

"Hi! I'm building an algorithm to construct a NURBS surface with pythonnocc 
and need to export it to a STEP file.

I construct a Geom_BSplineSurface with the command line

stepnurbs = Geom_BSplineSurface(stepptosctrl, steppesos, stepuknots, 
stepvknots, stepumults, stepvmults, k-1, l-1, 0, 0)

where all the parameters are already defined and it works well. Then I try 
to write it to a STEP file with the following lines

stepexporter = STEPControl_Writer()
stepexporter.Transfer(stepnurbs, STEPControl_AsIs)
stepexporter.Write(arquivosaida)

and I get the message error

TypeError: in method 'STEPControl_Writer_Transfer', argument 2 of type 
'TopoDS_Shape const'

At GitHub, I was told to execute the command

TopoDS_face(BRepBuilderAPI_MakeFace(stepnurbs, ...

but I still get a message error as below

TypeError: in method 'new_BRepBuilderAPI_MakeFace', argument 1 of type 
'TopoDS_Wire const'

Sorry if this may seems a noobie question, but I am not an specialist in 
python or opencascade, just starting to learn. :)

Best regards.
