Toolbar ‣ Poly Build

Poly Build combines several mesh editing tools into one, letting you work more quickly. It’s especially useful for retopology.

Tool Settings

Create Quads

When creating a new triangle that shares an edge with an existing one, automatically dissolves this edge so you’re left with a quad.

Controls

Adding Geometry Ctrl-LMB

Creates a new vertex at the mouse cursor, then creates a triangle using this new vertex and the nearest existing edge. If the existing edge already has two neighboring faces, instead creates a new edge using the new vertex and the nearest existing vertex. Holding Ctrl will preview the result in blue.

Deleting Geometry Shift-LMB

Dissolves the vertex/deletes the face under the mouse cursor. Holding Shift will highlight the target element in red.

Moving Vertices LMB

You can move a vertex by dragging it.

Extruding Edges LMB

You can extrude an edge into a quad by dragging it.

Tips

It is useful to enable Snapping and Auto Merge while tweaking vertices to combine them.
