The Adjustment tab enables you to make various adjustments to the lines. For example, you can offset the lines from the geometry, rotate them in 3D space and add overshoots.
To shorten the lines, enable the Resize Strokes option and set the Start and End values to where the lines should start and end as a percentage of their original length. Use the Variation values to vary the start and end for each line. Enable the Recalculate option to fit the stroke’s properties such as color and thickness to the start and end of the stroke.
The HSV settings vary the color of each stroke (or line segment if strokes are disabled) based on a percentage variation of the original color. You can enter a separate percentage for hue (H), saturation (S) and value (V). 0% means no variation, 100% means maximum variation.
The Start and End settings offset the line based on the direction of the Normals at the start and end of the line (center oil tanks). You can also offset the stroke using the X and Y boxes, which define how many pixels to offset the stroke in the computer screen’s X and Y directions (right oil tank). The Variation boxes vary the offset per stroke. 0% means no variation, 100% means maximum variation.
The 2D Transform settings scale and rotate the lines in the two dimensions of the computer screen. The Pivot setting defines the center of rotation and scaling: Start and End for the start or end of the line, Center for the center of the line, or Object for the center of the object. The Variation boxes vary the scale and rotation per line. 0% means no variation, 100% means maximum variation.
The Overshoot settings add straight extensions to the lines. The Start and End boxes define the length of the overshoots at the start and end of the line, either as a percentage of the line’s length (Relative enabled) or in pixels (Relative disabled). The Variation boxes vary the length of the overshoots per stroke. 0% means no variation, 100% means maximum variation.
These settings change the position (P), scale (S) and rotation (R) of the lines in three dimensions. The Transform option switches the transformation on or off.
