Opening the palettes
After properly installing Perspective into Illustrator's Plugins folder > Tools folder, launch Adobe Illustrator. Choose Window > Perspective to view the Perspective palettes. The first palette you need to use is the Perspective Grids palette.

Finding the tools
There are two Perspective toolgroups inside Adobe Illustrator's toolbox. Perspective icons are distinguished by their green point markings. The green points indicate the position of the mouse-click in relationship to the artwork created. Like other Illustrator tool groups, you can pop out the tools by clicking on the triangle at the end of each tool group.
