ArchiCAD Tip - Dormer Roofs and Solid Element Operations


Whenever dormer roofs appear, it is usually best-practice to use Solid Element Operations (SEOs) to take care of the subsequent required roof trimming.
The reason behind this is due the fact that:


The downside of SEOs is that the effect of the operation is only shown in 3D and Section/Elevation.
Floorplan is not affected in any way (which may in some cases cause an inconsistency between 3D and Floorplan)

A PDF outlining the steps for Solid Element Operations can be found here and also a link here shows a video on how to implement the operation.
