SelectionFilter without selecting

[SRSDS]

Is there a way to filter entities without actually "selecting" them.

ed.SelectAll(filter) causes the filtered selection to be selected I try to modify the previous selection.

Like "SELECT P", "MOVE P", "COPY P".

I really only want the filter to collect data, not select them.

Hi,

Simply iterate through the BlockTableRecord(s) in which you want to get entities and filter the entities accordin to your criterias.

This process is not slower than a SelectAll (which, internally, does the same).

Example to get all circles on layer "Foo" which radius is lower than 10.0

modelSpace
.Cast<ObjectId>()
.Where(id => id.ObjectClass.DxfName == "CIRCLE")
.Select(id => (Circle)id.GetObject(OpenMode.ForRead))
.Where(c => c.Layer == "Foo" && c.Radius < 10.0);
