    How to retrieve a specific named dimension in model

    Paolo Comand

      I need to retrieve a dimension with a specific name but I don't know the owner feature.
      EG I need to find all dimensions that have name "LPX@some feature@mypart.sldprt" without know what is "some feature". I have done it traversing the entire part for each single feature examining any single dimension. Is there a direct method without traversing the entire part or assembly?

      Thanks in advance

          Unfortunately, no, you will always have to traverse the part or assembly. Here I created a function called FindDimension that might make that simpler for you.


          'Demonstrates how to find a dimension by its name if the owning feature is unknown.
          'Precondition: Model is open and constant values are specified. Searching occurs in
          '   different contexts depending on whether the IModelDoc2 argument passed in is a
          '   part or assembly.
          'Result: FindDimension returns the **first** IDimension object beginning with
          '   DIMENSION_NAME or Nothing if not found.
          '-If you only want to search a single component, pass in the underlying IModelDoc2
          '   object of that component, obtained from IComponent2::GetModelDoc2.
          '-The topLevelOnly argument in FindDimension only applies to parts and assemblies.

          Const TOP_LEVEL_ONLY As String = False

              Set swDim = FindDimension(swModel, DIMENSION_NAME, TOP_LEVEL_ONLY)
              If swDim Is Nothing Then
                  MsgBox "Dimension not found"
                  MsgBox "Dimension found: " & swDim.GetNameForSelection
