Synopsis

moveVertexAlongDirection [-direction float float float] [-magnitude linear] [-normalDirection linear] [-uDirection linear] [-uvNormalDirection linear linear linear] [-vDirection linear]

moveVertexAlongDirection is undoable, NOT queryable, and NOT editable.

The command moves the selected vertex ( control vertex ) in the specified unit direction by the given magnitude. The vertex(ices) may also be moved in the direction of unit normal ( -n flag ). For NURBS surface vertices the direction of movement could also be either in tangent along U or tangent along V. The flags -n, -u, -v and -d are mutually exclusive, ie. the selected vertices can be all moved in only -n or -u or -v or -d.

Return value

None

Flags

direction, magnitude, normalDirection, uDirection, uvNormalDirection, vDirection
Long name (short name) Argument types Properties
-normalDirection(-n) linear createmultiuse
move components in the direction of normal by the given magnitude at the respective components. The normal is 'normalized'.
-uDirection(-u) linear createmultiuse
move components in the direction of tangent along U at the respective components where appropriate. The flag is ignored for polygons, NURBS curves. The u direction is normalized.
-vDirection(-v) linear createmultiuse
move components in the direction of tangent along V at the respective components where appropriate. The flag is ignored for polygons, NURBS curves.
-uvNormalDirection(-uvn) linear linear linear createmultiuse
move in the triad space [u,v,n] at the respective components by the specified displacements. The flag is ignored for polygons, NURBS curves.
-direction(-d) float float float createmultiuse
move the vertex along the direction as specified. The direction is normalized.
-magnitude(-m) linear createmultiuse
move by the specified magnitude in the direction vector.
