===== Object Tree =====

  * Contains all of the parts of your model
  * Contains a history of how they were made
  * Can group objects by clicking top-level object, select ''Create Group...'' a folder appears, then drop objects into these folders. Can show/hide by select a group and pressing space bar

==== Object Properties ====

   * Click an object, then a property window comes open that can be modified. The particular properties that appear are specific to the object selected.

===== Work Benches =====

  * **Draft** - Makes draft objects(?)
  * **Part Design** - Builds parts from parametric sketches. A "Main" work bench, offering great control, constraint-based
  * **Part** - Making CAD parts. An older work bench, has primitives like cube and cone.

==== Draft ====

Tools here can draw right into the 3-D space. 

**Construction Tools**

Items drawn when "Construction" is on, end up in a special **Construction** folder which can be hidden with space bar. For example, draw something in Construction, align things to it, then turn off the Construction object.

**Constraints (in Draft Workbench)**

Can lock down the coordinates and other properties. Can press X, or Y to constrain, or shift.

**Snaps (in Draft Workbench)**

Use some of the Snap tools. (Green icons.)

**Modify (not just change Draft Workbench items, can change anything)**

Blue icons in the Draft Workbench.
  * Rotate
  * Move
  * (others)

Read in the Wiki to see how to use the tools.

**Plane Control**

Allows you to draw at an offset from the main coordinate system. Can use to draw on different floors of a house, for example.
