Install the Atom package via the Atom preferences or via:
apm install landau-viewer
The plugin requires a instance of landau-packager to be running.
A preview pane for the currently opened file can be opened via
cmd-i (OS X).
As of now, the preview model is regenerated every time the file is saved or a component is selected from the outline viewer.
atom-landau-viewer was forked from
atom-jscad-viewer. Thank you to everyone who helped create it.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
