Highlights

Sweep Tool

The sweep tool fills the gap between the selected brush faces and a copy of those faces, called the destination cap, with a run of brushes.

Contributed by @ummjackson.

Creating and Editing Quake 3 Patches

A new control point tool allows you to edit the control points of Quake 3 patches like you normally edit brush vertices. Create patches from existing faces using Edit > Patches > Convert Selection to Patches. Adjust the numbers of control points without losing the patches' shape.

Arch Shape

The new shape for the shape builder tool allows you to create arches super quickly. Supports the same shape modifiers for cylinders as the other circular shapes.

Extrude Tool

The extrude tool can now extrude brushes that share a face, or a portion of a face, simultaneously.
