I would recommend you download the trial version and work a few examples with the rest machining process. You wouldn't be able to save cut files, but the on-screen toolpath preview would be enough to answer your questions. This applies to using vectors and other features as well, and includes access to 45 training videos and documents.
The link to download the trial version is here:http://www.vectric.com/WebSite/Vectric/ ... oducts.htm
The link for the first of 3 pages of tutorials starts here:http://www.vectric.com/WebSite/Vectric/ ... als_v3.htm
If you have any questions along the way, don't hesitate to ask. Good luck with your decision.
