Details
The user built a part using a revolved sketch, containing a "Symmetric Diameter" dimension in the profile.
Subsequently, when trying to create a PMI dimension out of this, they were not able to select it in "Copy to PMI".
The command does not recognise this type, whilst other dimension types are able to be selected. Why?
Solution
In this case the user selected the "horizontal" Reference Plane as the rotational axis, and used this as base for symmetric diameter dimensions. Since this is not "real" geometry, the "Copy to PMI" command is not able to convert the corresponding dimension into PMI.
The workaround is to use "real" geometry, e.g. the Base Coordinate System (X-Axis), or an "included" line ("Project to Sketch" using a Reference Plane) as the rotational axis for the Symmetric Diameter Dimension.
