Edit Tools > Quad Remesh

The QuadRemesh command quickly creates a quad mesh with optimized topology from existing surfaces, meshes, or SubDs. It uses a unique algorithm to generate manageable polygon meshes, ideal for rendering, animation, CFD, FEA, and reverse-engineering.


Target Edge Length

Sets the approximate edge length of the output mesh.

Target Quad Count

Sets the approximate face count of the output mesh as a goal for the algorithm.

Adaptive Size (0-100)

Set 0 to get a minimal number of quads and uniform sizes. A value above 30 will diminish your control of getting a smaller number of quads. Higher values result in smaller quads in high curvature areas. Set 100 to keep more details.

Face shape

As square as possible

Varies in width and height

Face size



Face density


Higher at details

Fit to original shape



Respect to target face count




Topology irregularities

More faces

Adaptive Quad Count

Use Surface Edges (Polysurface/Extrusion only)

Specifies if meshes edges will be created along the sub-face boundaries on the input object.


Ignores sub-face boundaries.


Retains sub-face boundaries except for the ones being determined as meaningless by the algorithm. This is usually the best choice.


Retains all sub-face boundaries.

Symmetry Axis: X Y Z

Select to perform symmetrical re-meshing across the X, Y, or Z central plane of the object's bounding box. Multiple axes can be selected. It only makes sense for symmetrical objects and when the correct symmetrical plane is selected.

Guide Curves

The quad re-meshing algorithm will try to place edge loops or edge rings along guide curves. Guide Curves can be used to define more details, or simply influence the direction of quad re-meshing in a region. Guide curves must be projected onto the input object to have an effect. Click Select Curves to select guide curves.

Curve Influence

These options control how guide curves affect the final quad mesh.


No effect on the result.


Adjusts the general direction of the quads by influencing their natural flow. The guide curves have a weak effect on the result.

Create Edge Ring

Orients the crossing edges perpendicular to the guide curves. The guide curves have a stronger effect on the result, but edge rings may not follow guide curves exactly.

Create Edge Loop

Places edge loops along guide curves. The guide curves have the strongest effect on the result.

Detect Hard Edges

Uses a 30-degree break angle threshold to divide the quad mesh with hard edges (creased edges). If the break angle between two adjacent faces is larger than 30 degrees, a hard edge loop will be added.

Turn this option off if...

Convert to SubD

Converts the resulting quad mesh into a SubD that results in a smoothed curved surface. Hard edges will be retained when possible.

This option is equivalent to the ToSubD command.

SubD Creases

Converts the creased edges added by the Detect Hard Edges option on the quad mesh into creased edges on the output SubD.

This option is equivalent to the MeshCreases option of the ToSubD command.

SubD corners

Converts the corner vertices on the quad mesh into SubD corner vertices.

This option is equivalent to the MeshCorners option of the ToSubD command.

Interpolate SubD

On - The quad mesh vertices are used as SubD vertices. The SubD will lie on the quad mesh. This is usually used for reverse engineering

Off - The quad mesh vertices are used as SubD control polygon points. The result will be slightly smaller or larger than the input shape.

This option is equivalent to the UseMesh option of the ToSubD command.


Previews the result of quad re-meshing. The preview will update when the settings are changed.

Preview calculates the average edge length and face count near the bottom of the dialog box.

Hide Input Objects

If the input object has dense wireframes, the preview will not be visible. Enable this option to see the preview.

Delete Input Objects

Delete the input objects when re-meshing is done.
