CAD drafting Scale 6 Command line: SC, SCALE

This command is used to decrease or increase the size of the selected objects whilst retaining their proportions (the scale factors along the X and Y axes are identical). If the scale factor is more than 1, the objects are increased in size; if it is less than 1, they are decreased. The specified scale factor value is retained in the current work session until it is changed again. The command is applicable to lines, polylines, circles, arcs, splines, and ellipses.

Command options:

?	Opens the additional options to select objects.
Copy	Scaling copy of the selected objects.
Reference length	Scaling the selected objects towards the reference line whose length is a single scale factor and a new length for the reference line.
Points	Scaling the selected objects towards the reference line whose length is a single scale factor and a new length for the reference line, specified by two points.
Non-uniform scale	Setting different scales along the X-axis and Y-axis. When scaling circles and arcs non-uniformly, they are replaced by ellipses.
