This bug happens when either the
Geometry or
Solution modes are active and you:
- Import another file that adds to the mesh (liml, dxf, etc) into the existing model or
- Remove a CAD file (step, iges) from the geometry branch after it’s been meshed and other elements have subsequently been added.
To dismiss the pop-up, move the mouse cursor off the graphics area and use the keyboard to close it (
Esc). Then save your work and restart Mecway because parts of the UI might not work anymore.
Sorry to everyone that's experienced this and it will be fixed in version 10.
