On a part, I am looking to designate a dimension which automatically updates if another dimension is changed. For examples if I have a round plate with 50 mm diameter, with a small hole of 25 mm in it. It means that the small hole should be 50% of the plate diameter. Is there a way I can set this up? I create lots of parts, where I want the part to update if I change one dimension. It means if I change the hole from 25 to 100mm, then the plate diameter should automatically upgrade to 200mm. Thanks in advance.
