SolidWorks price is ridiculous, it always has been. £4,800 outright plus £1,200 a year for updates. £6,000 upfront cost is just too much. Not that I would want increased yearly cost but they really need to move to a £200/month subscription model and they’ll see usage explode just like Adobe did.
I don’t know why cadjunkie has avoided mentioning Power Surfacing for SolidWorks in his list but it is practically the same as T-Splines so I don’t see why T-Splines is unique in the CAD world.
