Conceptually, I like the idea of a product like kipware. 25 something years ago I told the owners of SmartCam that it would be a good idea to continue their older 2.5 axis software as a separate product from their evolution into a 3D package. There were lots of users at the time that were plenty satisfied with the 2.5 axis package and had no use for 3D as their work did not require it. The 3D package was cumbersome and slow when being used to create 2.5 axis paths compared to the old 2.5 axis version.
Today, I wonder if the same holds true. Part designs have grown more complex in many cases. At least for the work I find myself doing, a 3D package is mandatory
