FreeCAD Rocketry Workbench

A rocket design workbench for FreeCAD

Demo Components

Install

Automatic

The Rocket Workbench is available as part of the Addon Manager. See https://wiki.freecadweb.org/Std_AddonMgr

Manual

Expand for Manual install instructions
  1. Obtain your user's default FreeCAD folder by typing the following in to the FreeCAD Python console FreeCAD.ConfigGet("UserAppData")
  2. Open a shell terminal
  3. Switch to folder in step 1 and append the Mod/ subfolder ex: cd ~/.FreeCAD/Mod
  4. Type git clone https://github.com/davesrocketshop/Rocket

The Rocket workbench will automagically download to your local machine.

  1. Restart FreeCAD for changes to take place.
  2. Rocket WB should now be available in the workbench dropdown menu.

Note: In order to keep Rocket WB up-to-date you'll need to follow Steps 2 and 3. But for step 4 replace with git pull
Again, restart FC to use the latest changes.

Materials

Materials are supported by all rocket workbench parts, but the core product support isn't currently up to the task. This will be improved in upcoming releases. For versions 0.20 and earlier you must apply a work around to see all the rocket materials.

  1. Load the Rocket Workbench. The necessary preferences will not be available until the workbench has been loaded.
  2. From the "Edit" select "Preferences...'. In the left hand column select the FEM Workbench.
  3. Select the "Material" tab at the top.
  4. Check the "Use materials from user defined directory". Set the directory to your user directory. For example, on Windows this would be "C:\Users\username\AppData\Roaming\FreeCAD\Mod\Rocket\Resources\Material"

Internationalization

This workbench has been written with multiple language support. If you are willing to provide a translation to your native language please open an issue and we'll work to get that done.

Reporting issues

The best method for reporting problems is to create a new issue in GitHub. Please include information such as the development branch you're using, instructions on how to reproduce the error, and where relevant a copy of the file in which the issue was encountered. The more information you provide the easier it will be to pinpoint the problem.

Feedback

For any feedback, features, and discussion please refer to the Rocketry workbench FreeCAD forum thread.
