Parallelism/Perpendicularity

Parallelism and perpendicularity constraints are set for pairs of lines or segments using the following methods:

constraint_item GCE_AddParallel(GCE_system gSys, geom_item g[2])

constraint_item GGCE_AddPerpendicular(GCE_system gSys, geom_item g[2])

Methods accept the following initial data: gSys is the geometric constraint system, g[2] is a pair of straight-line curves. The methods return a descriptor of a geometric constraint registered in the gSys system.
