Error in openning STEP and IGES

[mohrezarezaei]

Hi I want to use python occ to read a STEP file and change to shape into voxel representation but in the first step, in reading the file, i keep getting the "Standard Out Of Range" error, I also tried to read an IGES file and got the same problem. It is also worth considering that i have to skip the "Transfer Root" command as if i run it, my python stops operation. I use python 3.6 in windows 10 in Pycharm IDE and use Rhino 6 as my cad software. I hopefully look forward to your help

Can you please post a code snippet or provide the step file (if this is possible)?

Without anything, it's very hard for us to reproduce / understand, what kind of error you have.

sorry for being late. here is the code:

from OCC.STEPControl import STEPControl_Reader step_reader = STEPControl_Reader() step_reader.ReadFile("d:\a1.stp")

step_reader.TransferRoot()

bl = step_reader.Shape()

the error is :

Traceback (most recent call last): File "C:\Users\sarir\Anaconda3\lib\site-packages\IPython\core\interactiveshell.py", line 2862, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "", line 1, in runfile('C:/Users/sarir/.PyCharmCE2019.1/config/scratches/scratch_1.py', wdir='C:/Users/sarir/.PyCharmCE2019.1/config/scratches') File "C:\Program Files\JetBrains\PyCharm Community Edition 2019.1.3\helpers\pydev_pydev_bundle\pydev_umd.py", line 197, in runfile pydev_imports.execfile(filename, global_vars, local_vars) # execute the script File "C:\Program Files\JetBrains\PyCharm Community Edition 2019.1.3\helpers\pydev_pydev_imps_pydev_execfile.py", line 18, in execfile exec(compile(contents+"\n", file, 'exec'), glob, loc) File "C:/Users/sarir/.PyCharmCE2019.1/config/scratches/scratch_1.py", line 5, in bl = step_reader.Shape() RuntimeError: Standard_OutOfRange
