Pen Style

The Pen Style group controls the stroke's brush shape, open-path endings, and corner behavior. Start with Pen Shape, then refine open ends with Line Cap and corners with Line Join.

Controls

Pen Shape

Pen Shape

Pen Shape selects the brush model Thicc Pro uses to draw the stroke.

See Pen Shapes for how Round, Flat, and Sphere (3D) differ.

Line Cap

Line Cap

Line Cap controls how open stroke ends are drawn. Caps appear at open path ends, trimmed segment ends, and dash segment ends.

See Line Caps for the visual difference between Round Cap, Projecting Cap, and Butt Cap.

Cap Limit

Cap Limit

Cap Limit controls how far generated cap geometry may extend beyond the endpoint. It is a multiplier relative to the stroke radius.

See Line Caps for when it appears and why it can help animated strokes.

Line Join

Line Join

Line Join controls how corners are drawn where path segments meet.

See Line Joins for the visual difference between Miter Join, Round Join, and Bevel Join.

Join Limit

Join Limit

Join Limit controls how far generated join geometry may extend from the corner. It is a multiplier relative to the stroke radius.

See Line Joins for how it affects Miter Join and Round Join.
