I managed to find a way to create the pictures needed for documentation. The picture was created in FreeCAD by doing the following steps:
1. Open FreeCAD
2. Go to Edit>Preferences>Display>Colors to set the background white
3. Right click on the object and select Appearance or Ctrl-D
4. Under viewing mode, Select flat lines.
4. Under Material, select the ellipsis and choose white for all settings. Shininess is 0%.
5. Shape color is white, line color is black.
I found that for cylinders, only one line is present. To solve this for the purpose of creating drawings, a second cylinder with a 180 degree rotation is created to allow two lines. A rotation is applied to both cylinders to allow the proper view for the picture.
Additionally, an OpenSCAD script was written and imported to FreeCAD to create the model.
With the exploded assembly workbench, this can create the pictures needed for professional documentation.
