Select All Center Marks Example (C#)

In the SOLIDWORKS API, center marks can be features or annotations. Use these enumerators with ISelectionMgr::GetSelectedObjectType3 to return that specific type of center mark:

  • swSelCENTERMARKS for center marks that are features
  • swSelCENTERMARKSSYMS for center marks that are annotations

Traversal over the two types is different for the center marks that are:

  • Annotations. Use IView::GetFirstCenterMark and ICenterMark::GetNext
  • Features. Use IView::GetCenterMarks.

It is not directly possible to select center marks that are features, even though they appear in a feature traversal. This example shows how to indirectly select center marks that are features.

//------------------------------------------------
// Preconditions:
// 1. Verify that the drawing document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified drawing document.
// 2. Prints the path and file name of the drawing document to
//    the Immediate window.
// 3. Iterates the sheet and drawing views.
// 4. Prints the name of the sheet, drawing views,
//    and center mark annotations to the Immediate window.
// 5. Iterates the FeatureManager design tree.
// 6. Prints to the Immediate window that no center mark
//    features exist in the drawing document.
