three questions
1. in arx sdk,the class acgecurvecurveint2d and acgecurvecurve3d only support intersection
between acgecirarc(2d/3d),acgeelliparc(2d/3d) and acgeline(2d/3d).but in dwgdirect,it
doesn't description in detailed,then,does dwgdirect's odge library support all classed
that derived from odgecurve2d or odgecurve3d to calculate intersection points?
2. in arx sdk,the selection operated by acedss* functions,and in dwgdirect is oddbselectionset
and oddbselectionsetiterator.oddbselectionset seems does not support polygon style select
(including cross or not cross). then,how to get same effect by dwgdirect?
3. in dwgdirect, that has some classes,rtext,oddbwipeout for example. these classed supported
by et(extend tools) in autocad,and et does not release for all autocad user,then,if i using dwgdirect to
generate some drawings contain this entity can't release to my all user because of et.
have some good method to solve this problem?
thanks for reply!
