I have an occasional use for Solidworks (usually a few days a month). I use seats licensed by clients but increasingly would like it on my laptop; however, I can't justify a full license for my current needs. Is there any pay-as-you-use option? Ideally, I'd like to use a license server that logs usage and charges by the hour. I think it would make sense to buy the seat after needing more than about 800 hours per year, which means roughly -/hour. Any such options out there?
