I am relatively new to modeling (about one year) and am doing a learn/do project on my own and a lot of time on you tube, (MSBE Insights and MSBE Execution). QUESTION: Is it possible to use the resultant value of a Parametric/constraint calculation to validate against a requirement? I.E. I used a Par Block/constraint to add the lengths of some sub-components to come up with a resultant full length of a project piece, now I want to "bounce" that final figure off of a requirement.
