Can't get Column element

Hi there,

I use "ACAPI_Notify_CatchNewElement" to catch the modify of the element.

ACAPI_Notify_CatchNewElement(nullptr, ElementEventHandlerProc); ACAPI_Notify_InstallElementObserver(ElementEventHandlerProc);

And I indeed can get the event.however, if I create an Column or Beam,I will get an elemHead which it's typeid is "API_ColumnID" but with an empty body.

GSErrCode __ACENV_CALL d5c_sync::ElementEventHandlerProc(const API_NotifyElementType * elem_type) { GSErrCode err = NoError; if (err == NoError) { switch (elem_type->notifID) { // 新增 case APINotifyElement_New: case APINotifyElement_Copy: case APINotifyElement_Undo_Deleted: case APINotifyElement_Redo_Created: API_ElemInfo3D info3d; BNZeroMemory(&info3d, sizeof(API_ElemInfo3D)); auto err = ACAPI_Element_Get3DInfo(elem_type->elemHead, &info3d); break; } } }

The question is that : When i create a Column, how can I get the real element with the geometry information?

Hello,

ACAPI_Element_Get3DInfo doesn't get any 3D information for columns and beams because they are hierarchical elements (works like container). You should get all segments (API_ColumnSegmentType/API_BeamSegmentType) of column/segment and get their 3D information.
