What is the best way to start a parametric assembly - that has many weldment profiles.
Eg: if a length is updated - all the other dimensions updates. Is it best with Equations or Design table?
Is top down best or bottom up method so the parts linked in the assembly updates as well.
I would go with Design table. You can check these post for some example:
Example of Tank with Base - A Top-Down Main Assembly with two Subassemblies 100% parametric driven by user input table inside a DT and Ref_Geometry Part.
Configuring a Top-down Assembly from outside SW - User Input without opening SolidWorks.
