Inkscape extension: isometric projection converter
==================================================*This version of the extension is for Inkscape `1.2` or newer. For older versions of
Inkscape, please use [v2.1](../../tree/v2.1) (for Inkscape `1.0.*` and `1.1.*`), or
[v1.2](../../tree/v1.2) (for Inkscape versions before `1.0`).*This [Inkscape](https://inkscape.org) extension transforms objects drawn on a
two-dimensional plane to an isometric or dimetric projection.Inkscape provides an [axonometric
grid](https://en.wikipedia.org/wiki/Axonometric_projection) that by default is
configured for the [isometric
projection](https://en.wikipedia.org/wiki/Isometric_projection) (i.e., the
three axes are set at 120° angles). Drawing with this grid works quite well for
simple shapes, but sometimes it is easier to draw the details of an object
using a two-dimensional grid, and then scale, shear, and rotate the object to
set it on an isometric plane.This extension conveniently automates these transformations.
![Example created with this extension](doc/example.png)
In addition to the isometric projection (a dimetric projection where both angles are 30°), the
extension supports arbitrary angles as well (here the angles are set to 15°).![A dimetric projection example](doc/dimetric.png)
This example shows a trimetric projection with two different angles for the left and right hand sides.

## Installation
Copy `isometric_projection.inx`, `dimetric_projection.inx`, and `axonometric_projection.py` to your
Inkscape extensions directory, listed at `Edit » Preferences » System: User extensions`. After a
restart of Inkscape, the new extension will be available.## Usage
The extension can now be found in the **Extensions** menu under `Axonometric
Projection`. To convert a flat two-dimensional object
to one of the three visible isometric planes (i.e., top, left-hand side, and
right-hand side), select the object, and perform select the desired conversion
via the `Isometric Projection…` entry from that submenu.![Extension settings (isometric)](doc/dialog.png)
To perform the opposite action (i.e., convert from one of the isometric sides
to a flat two-dimensional object) select the appropiate isometric side, and
enable the *Reverse transformation* option.For dimetric projections using an angle other than 30°, use `Axonometric Projection » Dimetric
Projection…`, and set the angle to an appropriate value.![Extension settings (dimetric)](doc/dimetric-dialog.png)
For trimetric projections using different angles for the left and right hand sides, use
`Axonometric Projection » Trimetric Projection…`, and set both angles to appropriate values.## Further reading
