I need to model a curved wall element with some drilled circular holes in the surface. To create these holes in RFEM, I would normally draw a circle in the wall element to create the opening.
But how do I draw a circle on a curved surface?
To define openings and recesses in walls, it is necessary to define boundary lines of the opening. This is easy to do for plane surfaces.
It is trickier for curved surfaces. You can, however, do it by creating intersections. First of all, create an object that penetrates the surface at the desired location of the opening (in this case a pipe).
Then select the surfaces similtaneously and select "Create Intersection" in the context menu. This creates the intersection curves.
In the "Edit surface" dialog box, select the "Integrated" tab to view the created surface components. To create the opening, clear the check boxes for the active surface components that are no longer needed.
