Rather than add more and more symbols (blocks) to the gCADPlus setup file and make it unwieldy, we have developed a series of palettes that allow extra symbols to be added to gCADPlus. Each link takes you to a page that allows you to download a single gCADPlus file by clicking on the image. Once downloaded, use the BLOCKS command (or File > Insert) and then browse option to locate the new file and insert it while working on your current design.
Tip: It is a good idea to explode the incoming drawing so you can immediately see the new symbols. Drag into position and scale if required.
