Flatten Command

Although the Trackball tool is not intended to be a 3D modeling tool, it does introduce z-coordinate information that is saved in .cdx files. This pseudo-3D structure can be confusing when opening files that have been saved after perspective manipulation.

To remove perspective information:

1. Select a structure with the Marquee or Lasso Tool.

2. On the Object menu, click Flatten.

All z-coordinate information is removed from the structure.
