How to get properties of point in block reference C#

Hi,

How we can get properties of some points in block reference?

I tried with code:

var blockrf = (BlockReference)tr.GetObject(per.ObjectId, OpenMode.ForRead); var blockrc = (BlockTableRecord)tr.GetObject(blockrf.BlockTableRecord, OpenMode.ForRead); foreach(ObjectId id in blockrc) { DBObject entObj = tr.GetObject(id, OpenMode.ForRead); if (enobj is Point3d) // Error { var point = entObj as Point3d; } }

Point3d is geometric information of a location/position, not an AutoCAD entity. The point entity in AutoCAD is DBPoint. So, your code should be

if (enObj is DBPoint)

{

// this is a point entity in the block definition.

}
