Installation

  1. CLOSE THE CAD, if it is open
  2. Unzip ALL the package files in the same folder
  3. Run the installer
  4. By default, the plugin installation location is:

    C:\ProgramData\Autodesk\ApplicationPlugins\C3DMEMO.bundle

  5. If you change this location, or if you are using BricsCAD, ZWCAD or GStarCAD, you will have to load manually the plugin in CAD. In this case:
    1. Open your CAD program
    2. Type SECURELOAD on the command line and enter option 0
    3. Enter the command NETLOAD on the command line
    4. Select the compatible dll:

If the plugin does not load or the help file appears blank:

  1. CLOSE THE CAD if it is open
  2. Locate the folder where you installed the plugin
  3. Right click on the DLL (see compatibility table) and on the help files (./en-us/*.chm), click properties and click the Unblock button (IF IT EXISTS)
