kicad_oce_3D

This project is an out-of-tree 3D visualization plugin for the KiCad 3d_initial_merge branch. The plugin uses OpenCASCADE Community Edition (OCE) to provide the ability to view STEP and IGES solid models and assemblies.

In addition to the existing KiCad dependencies you need to install OpenCascade Community Edition:

https://github.com/tpaviot/oce

At the moment the build has only been tested on Linux with OCE as supplied by the package manager. It is assumed that the OCE package provides suitable FindOCE scripts for CMake. For OSX and MSWin developers, please provide feedback on installing OCE on those systems.

Building on Linux:

1. change into the kicad_oce_3D directory
2. create a build directory: mkdir build && cd build
3. configure and build: cmake .. && make

Note on building OCE on MSWin: (as provided by Jean-Pierre Charras, creator of KiCad)

The top level OCE CMakeLists.txt needs to be patched to build on W7-32 bit using MSys2:
