Each expensive action — site optimization, FEM analysis, PDF reports, DXF and BBS exports — costs credits proportional to the server compute it consumes. The cost catalogue below is exact and never changes silently. On every tier a single-column design costs 0 credits and an IntelliCascade™ solve 0.
Yes. Credit packs are available at the same per-credit price as your subscription and never expire. Subscribers get priority queue access for their own credits before consumption reaches the plan ceiling.
Students: upload any college/university ID card (JPEG, PNG, or PDF — up to 5 MB). Academics: upload faculty credentials AND provide your institutional email (.edu, .ac.in, .ac.uk, etc.). We review within 24 hours and you'll get an email with the decision. If rejected, the notes tell you exactly what to fix — you can resubmit immediately.
Credit-metered actions pause with a friendly prompt. Single-column designs, IntelliCascade™ solves and viewing saved work all continue to work. Top up a pack or wait until the next cycle — never a surprise charge.
Yes — 14 days of full access, no credit card required. You keep anything you've exported if you don't continue.
Free tier gives you the core design modules and 10 credits a month. Upgrade when you need FEM analysis and BBS export or more compute.
