Message #16083
PATCH: add option to VRML Export for Plain PCB
The attached patch addresses wishlist item #1393941 which is to add an
option
to export VRML models with no silkscreen or copper in the model in order to
produce a model which is easily converted to STEP format for use with MCADs.
This is useful for users who currently use VRML to obtain a mechanical model
to work with.
The diff is against rev. 5328. The patch has been checked on the
pic_programmer
and video demo projects by exporting a plain VRML board and exporting an
IDF board.
The IDF output was converted into a VRML model with the idf2vrml utility
and compared
with the output of the VRML exporter to verify that all holes (PTH, NPTH,
via) are
rendered by the VRML exporter.
