Intel based Macs do not have Classic. CADmover will not run.
The price is now $329, and there is a lite version for $199 that converts the most common CAD formats.
CADMover opens and saves CAD files. It is not a CAD program, but a coversion program. We use it to translate CAD files of cutting dies for product packages so we can fit the graphics to the die in Adobe Illustrator.
Some limitations are not with CADMover, but with the input file format. DXF does not have units in the file. CGM comes in as 1 layer. IGS is good, with the size accurate and layers.
There is nothing else like CADmover, so I can't say the price is unreasonable.
