There is no need to use Clockwork as this can be done with OOTB (out of the box) nodes like so. Again, pay attention to Dimension Type selected as it has to match the type that you are trying to replace. You can’t take an angular dimension and replace it with linear type.
EDIT:
To check dimension type style just use python like this:
#Assign your output to the OUT variable.
OUT = [UnwrapElement(x).StyleType for x in IN[0]]
