I don’t need 3D but I need splines, parametric dimensions, spline a = spline b, dim1= dim2*dim3/dim4, spline tangent to a at this point and b at this point, etc. I have too many dimensions that need parametric dimensioning to name all of them and have a spreadsheet (freeCAD uses spreadsheet). Trying Fusion, but I’d prefer cheaper and available to use for business because I would like to make drawings for business use (soliworks has a cheap version but cannot be used for business use).

Open to 🏴‍☠️ but soliworks requires key AFAIK
