Haven't used either, but as I understand it, there should be a NX release in the pipeline with very comparable features. I wouldn't be investing in a 3rd party toolpath update just now
I might investigate 3rd party solutions.
Whether I buy or not is another question
Production: NX10.0.3.5 MP5 + patch/TC11.2
I'd rather be e-steemed than e-diseaseled
I had imachining install a version on my machine last year and do a web demo. They couldnt even get it to work in the demo. The rep lashed out at me for being upset that they wasted my time. Pretty **bleep** service.
Purchased volumill the next week. Only thing I dont like about volumill is they dont have a "2d" version where you can control what it is looking at. It always looks at the full part which takes extra time on complex parts.
There is an option to reduce the engage spindel speed for ramp or helix movements. After engage move you can choose the "waiting time" to reach the spindel speed for side milling.
