The TechDraw DimensionRepair tool can adjust the 2D or 3D geometry references of a dimension. These references may become incorrect due to the "topological naming problem" or Hidden Line Removal.

See TechDraw LengthDimension for more on dimensions and the topological naming problem.


  1. Select the dimension to be corrected and, optionally, the new geometry references, points or edges, in the TechDraw View or in the 3D view.
  2. There are several ways to invoke the tool:
  3. The Dimension Repair task panel opens showing the selected dimension and the current geometry references.
  4. Select new geometry references if you have not done so already.
  5. Press the Replace References with Current Selection button.
  6. Press the OK button to update the dimension.
  7. If 3D references have been selected: optionally change the DataMeasure Type property of the dimension to True.

The TechDraw DimensionRepair tool cannot used in macros or from the Python console. Dimension reference properties can be updated using Python.
