Hello xavier.
Unfortunately CADViewX current version doesn't include methods to delete entities or methods programmatically from a group. Because of this entities can be deleted with CADEditor tool in Pro version. The following code shows deleting all entities from a layer with index j:

Code: Select all

     CADViewLib.Group entities = CADViewX1.CADImage.Converter.get_Sections(CADViewLib.TxConvSection.csEntities);
     CADViewLib.Group sel_entities = new CADViewLib.Group();
     CADViewLib.Layer del_layer = CADViewX1.CADImage.Converter.get_Layers(j);

     for (int i = 0; i < entities.Count; i++)
     {
         CADViewLib.Entity ent = entities.get_Entities(i);
         if (ent.Layer == del_layer)
             sel_entities.AddEntity(ent);
     }

     Editor = CADViewX1.GetCADEditor();
     Editor.Select((CADViewLib.Entity)sel_entities);
     Editor.Delete();

Thank you

It works.

There's just one thing I do not understand.
The delete function is defined as "Function Delete () As Boolean '.
Delete deletes correctly and returns false. .... ???

Hello.
Such results are not correct. Thank you for the remark. We have implemented minor changes in function body. So the returned value will depend on deleting results. The modification will be available with the next CADViewX version.
