Description

Round Cube at its base is a mathematical sphere with its vertices plotted like a cube, from six axis directions.

The base sphere is controlled by the Radius, Arc divisions and Odd Axis Align parameters.

The Size parameter enables extrusion of the base sphere outwards from its center resulting in additional edges and faces that can optionally be sub-divided using the Linear divisions and Type parameters.

Being a mathematical sphere, corners are not pinched, bevels are round, and polygon face sizes are more balanced (more uniform polygon surface area) than other methods (e.g. subdivision surface + cast or bevel modifiers). This add-on can produce any size (on x, y or z) capsule or cuboid. One of the disadvantages to consider is that non-spherical objects produced by this add-on will not scale well non-uniformly after they are generated.

Operator Parameters

Radius  Radius of mesh vertices for sphere or corners1 Size  Size of mesh per axis. Note: actual size of mesh is determined by the largest of either radius or size1. Arc Divisions  Arc curve divisions, per quadrant (applies to sphere or corners1). Set to 0 to derive Arc divisions from Linear divisions.2 Linear Divisions  Linear unit divisions (applies to extruded edges / faces)1; Set to 0 to derive Linear divisions from Arc divisions.2 Division Type  What parts of the extruded mesh are sub-divided (see examples): Corners  Sphere or Corners1. Edges  Sphere or Corners and extruded edges1. All  Sphere or Corners, extruded edges and faces1. Odd Axis Align  Align vertices with axes when arc divisions is an odd number. Note: this produces triangle corners!. (see examples) No Limit  Do not limit to 200000 vertices. Sanity check to prevent accidental creation of very large meshes. (applies to operator UI only) Number of vertices to be generated is indicated in brackets. 1.When specified size, per axis, extends beyond the vertices at specified radius. 2.Derived divisions indicated in brackets.

	Easy UV Mapping
	Use Follow Active Quads UV unwrap method to generate a classic cube/vertical cross map (front is Y+)

Operator Presets

Quadsphere Radius: 1, Arc: 8	Capsule Radius: 0.5, Size: (0, 0, 3), Arc: 8	Rounded Cube Radius: 0.25, Size: (2, 2, 2), Arc: 8
Grid 3D Radius: 0, Size: (2, 2, 2), Linear: 5, Type: ALL	Clay Bar Radius: 0.4, Size: (1.5, 3, 1), Arc: 8, Type: ALL

Divisions Type examples

Corners

Edges

All

Derived Arc or Linear divisions

Arc = 8, Linear = 0 (derived)

Arc = 0 (derived), Linear = 5

Arc = 8, Linear = 5

Odd Axis Align examples

Cube Arc = 1, Odd Axis Align = False

Octahedron Arc = 1, Odd Axis Align = True

	Single Vertex
	Using a Radius and Size of 0 will produce a single vertex without any faces
