Synopsis

roundConstantRadius [-append boolean] [-constructionHistory boolean] [-curveOnSurface boolean] [-name string] [-object boolean] [-polygon int] [-radiuss float] [-range boolean] [-rebuild boolean] [-replaceOriginal boolean] [-side string int] [-sidea int] [-sideb int] string string [string string]

roundConstantRadius is undoable, queryable, and editable.

The results from this command are three surface var groups plus the name of the new roundConstantRadius dependency node, if history was on. The 1st var group contains trimmed copies of the original surfaces. The 2nd var group contains the new NURBS fillet surfaces. The 3rd var group contains the new NURBS corners (if any).

A simple example of an edge pair is an edge of a NURBS cube, where two faces of the cube meet. This command generates a NURBS fillet at the edge and trims back the faces.

Another example is a NURBS cylinder with a planar trim surface cap. This command will create a NURBS fillet where the cap meets the the cylinder and will trim back the cap and the cylinder.

Another example involves all 12 edges of a NURBS cube. NURBS fillets are created where any face meets another face. NURBS corners are created whenever 3 edges meet at a corner.

Flags

Long name (short name)	[argument types]	Properties
-name(-n)	string
Name the resulting object
-constructionHistory(-ch)	boolean
Turn the construction history on or off (not available in all commands)
-object(-o)	boolean
Create the result, or just the dependency node (not available in all commands)
-replaceOriginal(-rpo)	boolean
Create "in place" (i.e., replace) (not available in all commands)
-curveOnSurface(-cos)	boolean
If possible, create 2D curve as a result (not available in all commands)
-polygon(-po)	int
The value of this argument controls the type of the object created by this operation (not available in all commands) 0: nurbs surface 1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion) 2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion) 3: Bezier surface 4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
-range(-rn)	boolean
Force a curve range on complete input curve (not available in all commands)
-rebuild(-rb)	boolean
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion. (not available in all commands)
-append(-a)	boolean
If true, then an edge pair is being added to an existing round dependency node. Default is false. You must specify an existing round dependency node when this flag is true. See example below.
-radiuss(-rad)	float
Use this flag to specify radius. This overrides the "-r/radius" flag. If only one "-rad" flag is used, then it is applied to all edge pairs. If >1 "-rad" flag is used, then the number of "-rad" flags must equal the number of edge pairs. For example, for four edge pairs, you must specify zero, one or four "-rad" flags.
-sidea(-sa)	int
Use this flag for compound edges in conjunction with the following "-sb" flag. This flag is not intended for use from Python. Please see "side" flag instead. You must specify the same number of "-sa" flags as "-sb" flags. If no "-sa" nor "-sb" flags are specified, then the edges are assumed to be in pairs. See also examples below. For example, two faces of a cube meet at an edge pair. Suppose one of the faces is then split in two pieces at the middle of the edge, so that there is one face on side "A", and two pieces on side "B". In this case you would use the flag combination: -sidea 1 -sideb 2. You must specify the edges in the corresponding order: roundConstantRadius -sidea 1 -sideb 2 isoA isoB1 isoB2;
-sideb(-sb)	int
Use this flag for compound edges in conjunction with the "-sa" flag. See description for the "-sa" flag. This flag is not intended for use from Python. Please see "side" flag instead.
-side(-s)	string int
Use this flag for compound edges. It replaces the sidea/sideb flags and is compatible with Python. The first argument must be either "a" or "b". You must specify the same number of "a" values as "b" values. If no sides are specified with the "side" flag (or sidea/sideb flags), then the edges are assumed to be in pairs. See also examples below. For example, two faces of a cube meet at an edge pair. Suppose one of the faces is then split in two pieces at the middle of the edge, so that there is one face on side "A", and two pieces on side "B". In this case you would use the flag combination: -side "a" 1 -side "b" 2. You must specify the edges in the corresponding order: // MEL roundConstantRadius -side "a" 1 -side "b" 2 isoA isoB1 isoB2; # Python maya.cmds.roundConstantRadius( 'isoA', 'isoB1', 'isoB2', side=[("a",1), ("b",2)] )
