cad.net 筛选、选择集_cad.net过滤选择集

过滤块

PromptSelectionOptions pOptions  =   new  PromptSelectionOptions();
TypedValue[] filList  =       { new TypedValue((int)DxfCode.Start, "INSERT") } ;
SelectionFilter filter  =   new  SelectionFilter(filList);
PromptSelectionResult res  =  ed.GetSelection(pOptions, filter); // ***
if  (res.Status  !=  PromptStatus.OK)  return ;
Autodesk.AutoCAD.EditorInput.SelectionSet SS  =  res.Value;
ObjectId[] idArray  =  SS.GetObjectIds();
