Perspective panel flyout menu
In the upper-right corner of the Perspective panel is a widget for a flyout menu with two utility functions.
The first option is only available when you have a 3-point perspective grid active.
The second option is available for any grid type.
Define 3-pt. grid
When you select “Define 3-pt. grid” the panel will change to show information about your current three-point perspective grid.
Adjust the sliders or enter values in the fields to change the Tilt, Turn, and Object distance settings. With the cursor in a field, press the Up or Down Arrow key to increment the values up or down. Press Shift for larger increments.
Preview your settings
AxoTools will display a cube with lines to the vanishing points, which will be visible whether Illustrator’s perspective grid is visible or not.
Apply your adjustments
Note that adjustments made here are not automatically applied to the perspective panel that is native in Adobe Illustrator. Plugins cannot affect those settings, so you will have to make those changes yourself.
Upon opening, the panel reads your current grid settings and recalculates a geometrically-correct location for the bottom vanishing point. You can either type the new vanishing point Y value into the dialog at View > Perspective Grid > Define Grid… or use Adobe’s Perspective Grid tool (keyboard shortcut Shift-P). Shift drag the vanishing point in the black circle to coincide with the orange circle.
For some grid changes, it will be helpful to select View > Perspective Grid > Lock Station Point so that the front corner of the cube and grid remain aligned.
The Perspective Grid tool has limitations, so you can get more reliable results by entering values into the dialog. Make certain that the bottom vanishing point X value remains at 0.
Click the Reset button to return the panel to the grid settings read when you selected the flyout panel. Alt-Option-click the Reset button to import the current grid settings to reflect any changes you made to Illustrator’s perspective grid.
Click the Done button to return the Perspective panel to its original configuration.
These values in the AxoTools Perspective panel can be entered into the four highlighted fields in the Define Perspective Grid dialog. Unfortunately, copy/paste is not possible in a “modal” dialog like this one.
Correct perspective distortion.
One of the issues AxoTools’ Perspective panel was created to address is distortion in some of the perspective planes. Path art can be projected onto perspective planes with the Perspective panel, but text on a perspective plane is handled by a separate plugin that only works in its own way. For proportional text, you can drag text to the perspective grid using the Perspective Selection tool.
Simply select the art to adjust and select “Correct perspective distortion” from the flyout menu. If the art is on a plane that distorts art, it will be re-scaled.
This applies to any art dragged to a perspective plane, not just text.
