.SH "NAME"
sca \- Used to apply a scaling factor\&.
.SH "SYNOPSIS"
.HP \w'\fBsca\fR\ 'u
\fBsca\fR {[sfactor] | [x\-sfactor\ y\-sfactor\ z\-sfactor]}
.SH "DESCRIPTION"
.PP
Applies a scaling factor to an object or view\&. When passed one parameter, an "object or view" is applied a uniform scale factor\&. When passed three parameters, an "object" is applied a unique scale factor to each axis\&. The effect is determined by the Transform option in the Settings menu\&. This is normally affected by the current mode of operation in MGED (e\&.g\&., matrix edit, primitive edit, or viewing)\&.
.PP
NOTE: Three parameters can only be applied in "matrix edit" mode\&. Only scale pipe and tori primitives uniformly otherwise raytracer and other errors may occur\&.
.SH "EXAMPLES"
.PP
The example shows the use of the
\fBsca\fR
command to apply a scaling factor to an object or view\&.
.PP
\fBExample\ \&1.\ \&Apply a scaling factor to an object or view.\fR
.PP

mged>\fBsca 2\fR
.PP
In matrix edit mode, the object being affected will get twice as big\&. In view mode, the size of the view will be doubled (showing twice the volume of space, hence making objects appear half their previous size on the display)\&.
.PP
\fBExample\ \&2.\ \&Apply a scaling factor to an object.\fR
.PP

mged>\fBsca 2 1 1\fR
.PP
In matrix edit mode, the object being affected will get twice as big along the x\-axis\&.
