`
Scale scales the carving to compensate for shrinkage after the extrusion has cooled.
It is best to only change the XY Plane Scale, because that does not affect other variables. If you choose to change the Z Axis Scale, that increases the layer thickness so you must increase the feed rate in speed by the same amount and maybe some other variables which depend on layer thickness.

## Operation

The default 'Activate Scale' checkbox is off. When it is on, the functions described below will work, when it is off, the functions will not be called.

## Settings

### XY Plane Scale

Default is 1.01.
Defines the amount the xy plane of the carving will be scaled. The xy coordinates will be scaled, but the perimeterWidth is not changed, so this can be changed without affecting other variables.

### Z Axis Scale

Default is one.
Defines the amount the z axis of the carving will be scaled. The default is one because changing this changes many variables related to the layer thickness. For example, the feedRate should be multiplied by the Z Axis Scale because the layers would be farther apart..

### SVG Viewer

Default is webbrowser.
If the 'SVG Viewer' is set to the default 'webbrowser', the scalable vector graphics file will be sent to the default browser to be opened. If the 'SVG Viewer' is set to a program name, the scalable vector graphics file will be sent to that program to be opened.

## Examples

The following examples scale the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and scale.py.
> python scale.py
This brings up the scale dialog.
> python scale.py Screw Holder Bottom.stl
The scale tool is parsing the file:
Screw Holder Bottom.stl
..
The scale tool has created the file:
.. Screw Holder Bottom_scale.gcode
