[Gmsh] cant export geo file as brep or step

[Mark Smith]

Hi gmsh forumI have a 3D geometry as a .geo file and want to export it for use elsewhere, when I try to export as brep or step I get the error : No OpenCASCADE model found? is there a setting required so I can do this?I get this error with gmsh versions 3.06 or 4.0.0
best regardsMark
