How does usage work?

Every job you submit draws on your monthly allowance, which resets on your billing date. Jobs are not all the same size: a Revit job does more work than an AutoCAD one and draws more, and a request that turns into a very large set of operations draws more again. A request you send to several drawings at once is one job per drawing, and each draws on your allowance like a separate request. Your project page always shows where you stand before you submit, and the small ring next to your plan name at the bottom of the sidebar fills as you use this month's allowance. Hover it to see the percentage used, or open Settings for the same percentage as a bar. If a job fails, the usage is returned to your account automatically, and a job that finishes without changing anything is not counted either.
