Unable to delete elementId of Dimension type

[Anonymous]

In my document there are list of unused Dimension types that Revit cannot catch in it's purge tool but I was able to delete through Revit API. The issue I'm facing now is when I hit the ElementId that belongs to specific Dimension Style Type (e.g. Angular Dimension Style, Spot Coordinates) in my list of unused, Revit will throw an error "Unable to delete ElementId". Revit not allowing to delete it unless those Dimension Style should have at least one Dimension Type that should retain within it.

Is there a way to skip that error and not try to delete it and then continue deleting my other ElementId in the list?.

When you say, 'throw an error', i assume you mean that an exception. is thrown.

If so, then yes, you can catch that specific exception and proceed with the next element id.

Look for '.NET try catch' to learn how to use that:
