A parametric CAD will always shine, when later changes are needed. Aspire will shine in a workshop environment for everydays stuff, simple jobs, signs, carving. The fluidity when making signs or carvings is uncomparable. Try that in other program and you will soon get frustrated.

One main thing that i start to miss very much in Aspire is trochoidal toolpaths. Its annoying and i see no reason why they don't include that, given its price. Now i am playing around with Estlcam which is 50euro and has that function. By the way I highly recommend that program as very intuitive and capable and am thinking to buy a license.
I could make the same in NX9 CAM part but i have to spend 1h deciding 50 details just for a simple pocket. Hence i start to need a simple CAM for the trochoidal toolpaths. That's why i am testing now the EstlCam. This program has one little very annoying detail that if fixed could be a serious contender even for Aspire. I am planning to contact the maker. Its that you don't see a toolpath list window like in other programs, but instead have to simulate the cut to see the various toolpaths and their order. Fix that and there will be a wow prog for 50 euro.
