We are going to build simple CAD that is easy to learn and easy to use.
Although FreeCAD has provided a lot of powerful functions, we found that FreeCAD is not easy to learn and has a lot of bugs. So we hope to build a new CAD that doesn't need t be powerful but easy to use.
We found that open cascade visualization doesn't support wayland(Link). So we decided to use another visualization library. We found that FreeCAD uses Coin3D and Coin3D can be displayed on wayland. But there is no document about making OCCT and Coin3D work together.
