✅ Re-run any study when a building or an engine version changes

A building bought outright is USD 149.00, so Practice pays from the 4th building of a year. Below that, buying passes is the better deal — and it stays available.

There is no free trial, because the free tier is the trial. You can model your actual building and run all three studies without paying or committing to anything — real inputs, real engine, every verdict and all the working on screen. A trial that could also issue documents would just be a free month of the whole product; one that could not would show you nothing this does not already show you. So we skipped the countdown and left the door open.

A Building Pass covers one structure. Payments are processed securely by Paddle, our Merchant of Record, who handles invoicing and applicable taxes. See our Terms and Refund policy.
