Hi ! I've been using 3D modeling software like Ideas, Solidworks etc. for a long time ... but they have one deficiency ... price :grumpy: ! At times I've tried cheaper alternatives you can find from the net ... but always had to revert to these "dinosaurs" when some features haven't quite cut it etc (usually when you have complex 3D curved volumes is when this happens). I use 3D modeling software primarily for geometry modeling + mesh generation, i.e. like finite element analysis for PDE solving. Are there any good alternatives out there instead of using the good old "high - rollers" ?
