Wall Behavior or ArchiCAD and Constructor

This document provides a summary of behaviors for the wall object in current ArchiCAD and Constructor, GraphiSoft.
The Appendix is quoted directly from the help file in Constructor. It provides detail information of a wall object including its constructions and behaviors.
Five tasks are to be investigated in this report, including:
1) Is a wall segment delimited to have a single floor plane?
2) Is a wall also delimited to a single roof plane?
3) Can a wall have non-horizontal changes in construction (through its cross-section)?
4) Does the wall object support internal framing layout?
5) Can a wall be a lofted surface, with a bottom curve and top (or intermediate curve) that is lofted between?

In fact, ArchiCAD and Constructor are tailored to different users. Building Objects (BO) in ArchiCAD are preliminary objects with less information for construction and detailing purposes. It is primarily to be used by Architects rather general contractors (GC).

1) Is a wall segment delimited to have a single floor plane?
No necessarily, building objects can be automatically trimmed by other objects in Constructor.
Objects such as wall, column and beam are automatically clipped by the intersect roof or slab. Most are unredoable to their original status except slab clipping, meaning slab is clipped without being able to convert back to its initiative status. Slop is another object then slab where slab is considered a single horizontal element, with or without openings. A step-like slab is a composite element by composing multiple segments as one grouped piece or alternatively, using a stair object to imitate a step-like slab. Wall, as a single piece, will be clipped automatically by a step or slope object if intersect.
