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.

Options

Target Quad Count

The target face count of re-meshing. It is a goal for the algorithm. The final face count may be higher or lower.

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.

Use Surface Edges (Polysurface/Extrusion only)

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

Off

Ignores sub-face boundaries.

Smart

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

Strict

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.

Enabled
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.

None

No effect on the result.

Approximate

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.

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.

Preview

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

Hide Input Objects

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