Patch Grids

Quad Patch
Quad Patch creates a flat grid with a default of 36 visible rectangular facets. A hidden line divides each facet into two
triangular faces for a total of 72 faces.
Procedures
To create a quad patch:
- On the
Create panel, activate
(Geometry). Choose Patch Grids from the drop-downlist, then on the Object Type rollout, click Quad Patch.
- Drag in any viewport to define the length and width of the patch.
To edit a Quad Patch:
-
Select a Quad Patch.
- On the Modify panel, right-click Quad Patch in stack view and choose Editable Patch.
The Quad Patch collapses to an Editable Patch.
- On the Editable Patch Selection rollout, click
(Vertex).
- In any viewport,
select a vertex on the patch object, and move the vertex to change the surface topology.
Vertices and vectors can be animated with an Editable Patch modifier.
At the Edge sub-object level, you can add patches along any edge. You can create complex patch models beginning from a single
patch.

-
Creates a patch based on the XYZ, Length, and Width values.
Parameters rollout
- Length, Width
-
Sets the grid dimensions in current units.
- Length, Width Segments
-
Determines the number of facets along the length and width of the grid. Default=1.
The density of a Quad Patch rises sharply as you increase the segments. A Quad Patch of two segments on a side contains 288
faces. The maximum is 100 segments. High segment values can slow performance.
- Generate Mapping Coordinates
-
Creates map coordinates for applying mapped materials. Default=off.
