How can I get the coordinate of selected points

[zzzhr]

Hello,
When I use cadImage.SelectExt() function to select an entity,it seems that I can select a single point of this entity(It turns red when selected),but how can I get the coordinate of this selected point?
thanks.

Hello.
CADImage.SelectExt method selects an entity at the specified point, not the single point of entity.
