One where the optional line lenght is controlled by offset from the wall edges and not the middle of the wall....where the line should stay in the wall while movin the marker text...where it should be possible to add an angled line to the line that is orthogonal to the wall. Maybe there is one somewhere out there...?
Maybe you should make this into a wish for a new BIMComponents object.
I don't know at this moment if it is technically possible to do in GDL, but it may be, given all the things that are possible with the recently created Ceiling Editor Object.
