I have scalable 3D models (assemblies) for various impellers that require a different number of holes in the bolt pattern depending on the power draw of the system. I would like to create drawings for the blades so my fabricators can have a cutout pattern. The problem I run into is in dimensioning the hole pattern when the number of holes changes in my models. I have to manually delete and re-insert the hole pattern dimensions. This process becomes very cumbersome when I have to do hundreds of this drawings. I can't use a design table to vary the hole quantity because the complexity of the calculations used to dimension the impellers forced me to use design tables for a different purpose. Is there a way to automatically change the hole pattern dimensions in a drawings when the number of holes is increased or decreased?
