I have noticed that some AutoCAD verticals (maybe
even ACAD itself) use some sort of temporary graphic entities. They are commonly
used as error markers during topology creation (Map), for example. When user
issues REGEN command, they simply disappear. Just like they were never actually
written into the database (DWG).
What's the common ACAD term for such
"temporary" entities and does ObjectARX (2005/2006) expose some sort of function
for drawing/deleting them? Are there .NET examples available?
right. I recall using these two Lisp functions years ago to
achieve described effect. Mike mentioned AcEdJig .NET API class exposed in
ObjectARX 2006, and I guess this is a topic to start researching further
(although still not sure if this is the right thing). Jig
enables a "rubber band" (ghosting) effect.
