Description[edit | edit source]

The TechDraw ExtensionAreaAnnotation tool calculates the area of selected faces and inserts an area annotation.

On the right the inserted area annotation

Usage[edit | edit source]

  1. Select one or more faces.
  2. Select the TechDraw → Attributes/Modifications → Area Annotation option from the menu.
  3. The total area of the faces is calculated and an area annotation is inserted.

Limitation[edit | edit source]

  • 0.21 and below: The tool cannot handle faces with curved edges.
  • Holes (islands) in the selected face are ignored. This forum post shows a workaround. You can also use TechDraw AreaDimension but you must then correctly set the DataReferences 3D property of the created dimension.
  • The calculated area is not dynamically linked to the face. If the area of the face changes the text is not updated.
