""" Netgen OCC documentation
|
|
|
|
This module provides the Netgen OCCGeometry class, as well as Python wrappers
|
|
for OpenCascade functionality. This allows the construction from scratch, as well as
|
|
editing geometries imported via STEP format.
|
|
|
|
Most of the classes are directly py-wrapped from the OCCT classes.
|
|
For more detailed documentation consult the OCCT docs, a good starting point is
|
|
https://dev.opencascade.org/doc/refman/html/class_b_rep_builder_a_p_i___make_shape.html
