In my search for a way to create dynamic blocks, other than purchasing AutoCAD, I asked another vendor if their product supported this. He replied that Autodesk patents prevent them from offering this feature. But, apparently, the software vendors are not concerned over offering the ability to use existing dynamic blocks. I am puzzled over the difference.
I know vendors such as IntelliCAD and Bricsys have to create a way to read/write to the DWG files where we store our drawing data. They are not really reverse engineering the software. Rather, they are reverse engineering the DWG format. Can't they do the same for the Dynamic Block object?
I know the vendor I corresponded specifically said the Dynamic Blocks are patented. But, are any other types of drawing objects also patented?
GStarCAD is the only other program I know of, that offers the Dynamic Block creation feature. If there is a patent issue, how do they get around it? Or perhaps they ignore it.... China is not exactly known for recognizing intellectual property rights. This is part of my company's hesitance to purchase that program.
