opo is an Adobe® Illustrator® Plug-in designed to automate the creation process of Parallel 3D Effect. This type of graphical modification is better known as Oblique Projection. Oblique is not really a 3D system but a 2 dimensional view of an object with 'forced depth'. One way to draw using an oblique view is to draw the side of the object you are looking at in two dimensions, i.e. flat, and then draw the other sides at the given angle, for example 30 degrees:

// Geometry of the Projection
The User Interface is very simple. It has three logical parts. The first one controls geometry of the Projection. XY stands for projection specified by horizontal (X) and vertical (Y) variables. And DA for projection specified by depth (D) and rotation (A) variables:

// Direction of the Projection
Projection Z-order option specifies whether the projection is being created in front of screen plane ‘Z+’ (towards the user) or behind the screen plane ‘Z-’:

// Separate Layers
Take a note: opo separates the Oblique Projection product into 3 ‘logical’ parts: a) original front art, b) its projection and c) back art. Each part has its own layer: a) the front art – current layer, b) the projection – [current layer name]_PZ-/+, c) the back art – [current layer name]_BZ-/+. For example:

// Projection Type
opo supports both: solid and wireframe projection:

// opo vs Curves
opo automatically calculates and creates extra tangent points (i.e. points at which the projection line “just touches” the curve) if necessary. This way the new projection structure perfectly matches the front art path! No gaps and no approximations - the new point perfectly fits the curve at its local maximum:

// Color Control

Do not apply Custom Color.This option copies the formatting from the front art and applies it to the created projection objects:

opo color properties: none
opo color properties example: none

Custom Projection Color (solid). Applies user’s custom color formatting to the created projection. Each projection art receives the same fill/stroke color properties:

opo color properties: solid

You can either copy color properties from any existing art object (via Copy Color Formatting button) or specify RGB/CMYK values directly by its numerical value:

Custom Projection Color (blend). Blends projection color between front art appearance and user’s custom color (fill and stroke). opo provides the optimum number of steps for the smooth color transition:

// Easy Selection
Since opo separates the Oblique Projection product into 3 ‘logical’ parts, you can easily access/select each group via the Layers Panel:

Of course, you can also modify the projection objects one by one, using Selection Tool. Just select some items and modify its appearance as required:
