Many situations can force a change to the building model. In this chapter we describe the various functions using different examples.
Suppose you receive a changed floor plan. An existing polygonal room or area gains or loses a part of its surface, which changes the number of corner points and walls.
Suppose you have created a building model based on a floor plan. You receive a changed floor plan, in which walls have been moved.The function Move Area moves the coordinates within one or more move areas together in the same direction and by the same distance.
Suppose you receive a changed floor plan. A large room has been divided into two smaller rooms.
Suppose you want to assign different properties to a wall at a certain position. The room geometry is to remain unchanged. In this case, you can split the wall at the desired position into separate segments and then set the properties of both segments independently.
Suppose a straight wall was divided into two segment in an earlier stage and you need to place a door or window on the position of the dividing point. In this case, you must first merge the two wall segments because the division points limits the wall and causes similar behavior as a room corner.
The functions SuspendedCeiling and Object-Group (Area) align automatically to the reference wall of the room. If you require a different orientation, specify another reference wall.
Suppose, by changes in the plan tow previously remote rooms become adjacent rooms. Possibly a room is deleted and the outer walls of the other remaining rooms move towards each other. In this case, you need to make a relationship between the opposing room boundaries.
