The 2D editor (Outline.exe) that is included with Active Dimensions 3 can be used to create surfaces of rotation or to create planar geometry for extrusion in Active Dimensions 3.

Adding And Inserting Points
-------------------------------
Click a location within the window to add a new point there. A newly added point will be connected to the last point. You can drag any point to any location. You can also insert a point between any two points by clicking anywhere on the segment that joins the two points.

Deleting Points
---------------
To delete a point, select it and then press the delete key on your keyboard. You can choose "Select All" on the "Edit" menu and press the Delete key to delete all points simultaneously.

Opening a Background Image
--------------------------
You can choose Open Background Image on the File menu to open a bitmap so that you can manually trace its outline. For all but the simplest outlines it is recommended that you first draft it in a 2D graphics editor and save the image as a bitmap so that it can be traced. See the "Getting Started" section below for more information.

Save As Planar Geometry...
--------------------------
Choose this menu item to save your outline as planar geometry to be extruded in Active Dimensions 3.

Save As Surface of Revolution...
--------------------------------
Choose this menu item to generate and save 3D geometry that is formed by rotating your outline 360 degrees about a vertical axis. The axis about which the outline is rotated is located at the very left of the window.

Getting Started
---------------
Load the 2D editor. On the File menu Choose "Open Background Image..." and open the bitmap named "Outline Tutorial" for a very simple tutorial on how to create a 3D pulley.

After completing the tutorial, try saving the same outline as planar geometry and see what happens. You will be able to extude the geometry in Active Dimensions 3.

You can also create a pulley without a hole in the center by following the steps below.

Delete the last point you added. (The last point was placed in the same location as the first point.)
Drag the point that is directly below the  first point to the very left of the window.
Then drag the first point to the very left of the window.
Now choose "Save As Surface of Revolution..." from the File menu to save the new pulley.
In this case a fully enclosed outline was not needed.
