But this slows AutoCAD terribly. It freezes for a few seconds every time I'm near an entity in model space, even before I actually do the selection. Any help, because this way it is impossible to do any work in AC. I use OPM properties to read/write objects XData.</P> Fri, 03 Apr 2020 09:49:24 GMT tamara 2020-04-03T09:49:24Z https://forums.autodesk.com/t5/net-forum/autocad-very-slow-after-loading-custom-properties-to-opm-using-c/m-p/9419738#M19895 <P>Hi,&nbsp;</P><P>guided by few examples on how to load custom properties using&nbsp;IDynamicProperty2, IDynamicEnumProperty and ICategorizeProperties, I get my properties to show and work.
