std-arc-pt, std-arc-endpt | ![]() |
STD-ARC-PT returns the first point of an ARC entity. This will fail if the entity is no arc.
If it is an ARC it is the same as (STD-GETPT) only faster.
STD-ARC-ENDPT returns the end point of an ARC entity. This will fail if the entity is no arc.
If it is an ARC it is the same as (STD-GETENDPT) only faster.
It may be used with entity types, entget-lists or entsel picklists.
Note
The implementation calls STD-ENTGET on ename or entsel arguments which uses an entget caching mechanism, because ENTGET is usually slow. But this speed gain may fool return values on deleted entities.
ele: An ARC entity of type ENAME, a entget-list or entsel picklist.
Either a 3D point or nil.
None. It may set an internal *ENTGET-CACHE* symbol, but direct access is forbidden.
