If you experience an Error with coMotion after installing (ie, typing in COMONXT and the command line and the return is "Command Unknown") It is probably one of 2 things. The main LISP (comonxt.VLX) or OpenDCL is not loading. Follow these steps to see if it one of these issues:

OpenDCL

  1. Type OPENDCL at the command prompt. If nothing happens, then all is fine...
  2. If you receive an error "unknown command OPENDCL" you will need to add the OpenDCL ARX to your startup suite (APPLOAD). The file version varies depending on your version of AutoCAD. The files are located at "C:\Program Files\Common Files\OpenDCL" on 64 bit systems it is located at "C:\Program Files(x86)\Common Files\OpenDCL"
