I’m trying to automate a multi-section propeller blade (10–11 airfoil sections) in SolidWorks using the API, but the geometry keeps breaking — sketches fail, splines break, constraints don’t apply properly, and sections sometimes get misplaced. Automated rebuilds are very unstable.

Is there any reliable way to improve automation for this type of geometry in SolidWorks (API, macros, design tables, equations, etc.)?

Or is SolidWorks simply the wrong CAD tool for heavy parametric blades?

If so, what CAD tools are better for fully automated geometry generation?
I need something that can handle:

• programmatic section creation

• parametric airfoil definitions

• automated lofting across many sections

• batch regeneration for optimization loops

Any recommendations or real-world experience would be super helpful. Thanks in Advance!!!
