Open CASCADE is a powerful CAD/CAM/CAE kernel and development platform for 3D modeling applications". Few open-source application like FreeCAD and HeeksCAD are already using OpenCASCADE as their 3D modelling framework and it would be good to have OpenCASCADE packaged in Fedora-compatible way. Unfortunately due some issues in the license it's considered not free enough for Fedora. A lot of packaging work has already been done by the Debian maintainers so I have used their patches and package layout, some of the patches were improved by me and few new ones were created and all were sent back to share the work. Fedora packages are now available in my repository, packages for RHEL/CentOS 5 will follow tomorrow (it takes some time to upload GBs of data on Asymetric DSL with 512 kbit upload). Also available is HeeksCAD package, so you can see it really works. I expect that OpenCASCADE will land in the RPM Fusion repository in the near future and it live there until the licensing issues are cleared and it can accepted into Fedora directly.Quoting from its home page "
