The links attached here can be used to enhance your copy of gCADPlus by adding new symbols. Each link allows you to download a gCADPlus file. Once downloaded, use the BLOCKS command (or File > Insert) and the browse option to insert the drawing into your current design.
Tip: It is a good idea to explode the incoming drawing so you can see the incoming symbols. These can then be dragged into position. The YouTube movie below shows how to use the system.
