Draft Special/tr

Description
When this snap location is activated, special snap locations defined by object are available. These include:


 * Vertices of base lines of Arch Walls
 * Base points of Arch Structures
 * Any point defined in the Snap Points property of objects, if existing (Currently only Arch Equipments have such property). The 3D vectors defined in the SnapPoints property (a VectorList property) are transformed together with the object placement before snapping.
