extracting properties of entities
(**case closed**) extracting properties of entities
i have managed to get to and iterate through the list of entities in a block and i can print out their classnames and which layer they belong to. these are mostly acdbxxx entities (acdbline, acdbtext, etc) but when i searched in header files for those words i did not find anything. can someone help me how to read attributes (startpoint, endpoint, radius, thickness, color, etc.) of acdbxxx entities?
thanks
-----------
i was reading the names of the entities returned from pent->isa()->name() which returned strings like "acdbline" etc. and thought that the entity is actually an instance of acdbline c++ class. but the entity is actually an oddbline, etc. replacing ac with od does the job.
sorry for bothering.

hi,
the analogues of acdbline is oddbline, acdbcircle is oddbcircle, etc.
in dwgdirect there are no acdb c++ classes.
i guess the isa()->name() function returns the name of the class as found in the dxf specification (acdb- prefix), in order to keep consistency with acad. in this case this is only a string description and not a c++ class.
so use the oddb classes and you'll get the results you need.
btw same with acge and odge, acgs and odgs, etc
hope this helps.
best regards
