I thought that you would be interested to know that Delcam are giving free online demos of their CADCAM (Computer-aided Design & Manufacturing) software range.
The next demonstration to take place is for ArtCAM Insignia on the 24th of March which is the mid-range software package and will demonstrate how to design a cabinet, create multiple drill holes and then nest the pieces according to their true-shape.
If you want to see what ArtCAM Insignia is all about, here is the link for the demo times, etc.
If you want to find out more about the software before the demonstration you can also go to:www.artcaminsignia.com
I hope you find the demo useful.
