 I've been slowly getting my head around the new (FreeCAD 1.0) assembly workbench, and using it to create exploded diagrams for my upcoming book, Learn Robotics Programming Third Edition.

 ## Knolling before the assembly
 
 When you make the assembly in FreeCAD, you insert parts from your open documents into it.

 For the photos I use in my books, I lay parts that I would assemble on a workbench (trying to find a good white surface for photos), so they can all be clearly seen and the quantity.
 This technique is known as knolling, and creates quite pleasing assembly instructions.

 The same technique is handy when making FreeCAD assemblies, making the parts easier to assemble into place with joints/constraints afterwards:

 You can do this by using the drag handles on the parts when you've added them.
 If you lose the drag handles, while still in the add parts mode, you double click a part to get them back.

 I use boolean operations a lot in my Inkscape 2D drawing workflow, to construct shapes, so it is nice to have them in FreeCAD too.

+## Creating exploded diagrams
+
+You can explode an assembly by selecting an assembly in the workbench, and pressing "E", or finding Exploded Assembly in the menu.
+
+My technique is to CTRL-select groups of bolts together and lift them out of the assembly, just remember to give clearance for other parts to come off too.
