Plans Sized for Engineering Firms at Every Volume

A drawing set is one complete generation from a single project intake. This includes all sheets produced in that generation pass: single-line diagram, panel schedules, riser diagram, load calculations, and arc flash documentation. Revision regenerations (when a PE flags a sheet for correction) do not count as new sets. Only the initial generation per project counts toward your monthly limit.

No credit card is required to start the free trial. You create an account, submit your first intake, and receive a complete drawing set. After the trial generation is complete, you choose a plan if you want to continue. If you do not upgrade, the trial account remains active but no additional generations are available.

Yes. Upgrades take effect immediately and the prorated difference is charged to your payment method. Downgrades take effect at the next billing cycle start so you keep your current plan features through the period you have already paid for. If you are on annual billing and need to downgrade, contact support and we will apply the change at your renewal date.

When you reach the Starter plan limit, you can upgrade to Professional to continue generating that month, or wait for the next billing cycle. We do not charge overage fees. If you regularly hit the limit within the first two weeks of a billing cycle, we recommend upgrading to Professional, which removes the per-month cap entirely.

Yes. The annual Starter rate of $254/month versus $299/month monthly billing works out to 15% savings. The annual Professional rate of $764/month versus $899/month monthly is also 15% savings. Annual billing is charged as a single upfront payment at the start of each subscription year. There are no installments.
