In Modeler, the retopology tools are based on Houdini’s standard TopoBuild state, but with a key difference in how the modes are activated. In Houdini, TopoBuild modes are triggered using the Shift+1...6 hotkeys. In Modeler, all retopology modes are conveniently grouped in the Topo radial menu. This allows you to activate any mode directly from the menu without needing to first activate the TopoBuild Houdini tool and then select a mode. If the TopoBuild node hasn’t been created yet, activating one of the Build, Slide, Split, Brush, or Smooth modes from the menu will automatically it.

Draw Patch

The Draw Patch tool allows you to create patches by drawing contours. Automatic snapping of the cursor during drawing makes it easy to connect patches together. By hovering the cursor over the drawn curve and using the mouse wheel or pressing keys 1 or 2, you can control the number of subdivisions on the patch's side.
