[st-users] FACETED_BREP_SHAPE_REPRESENTATION

[Blair Downie]

Walter,

What is WiseView?

You might also try our ST-Viewer product
(http://www.steptools.com/products/stviewer) for viewing the faceted brep
files.  Using ST-Viewer you can generate both a solid and wireframe view of
the model.  In wireframe mode, you can then pick the individual poly loops.
Then you can view the definition of the poly loop in the STEP file.  The
viewer doesn't currently have anyway to display the topology of the faces.

Specifically, any way to illuminate the topology rules.  E.g. how can I see
which direction the vectors point in?
