The frustrating part, and I do mean frustrating, is that I don't know what I'm not getting... and it is taking way too much of my time. I have a lot to do right now.

To accomplish the [Open Source Ecology Developer Test](http://opensourceecology.org/wiki/Developer_Test) (OSE), I need to be able to put some parts together in a cube, install bolts and draw my initials on a part.

There are a bunch of developer tests there to look at, and I've hunted down a bunch of videos on YouTube. I know that to assemble the parts in FreeCAD that I need to do it in Assembly2. I have tried in vain for hours.

I can get it done in Blender, no problem. I downloaded the parts from the [OSE Part Library](http://opensourceecology.org/wiki/OSE_Part_Library), opened it in FreeCAD, then converted the file to Stl, which Blender can understand, and built the project in short order.

#### Rendered (I did forget to put my initials on it).

How do I learn this? Obviously I'm overlooking something basic.
