Vertessia
What Vertessia is
Vertessia converts meshes and scans into editable STEP CAD surfaces. Its Organic mode produces smooth NURBS patches, while Mechanical mode fits planes, cylinders, and cones. Accepted formats are STL, OBJ, PLY, 3MF, GLB, glTF, and STEP, with uploads up to 100 MB. The service also provides mesh format conversions and STEP-to-mesh conversion without charge or an account.
A free account enables reconstruction and a browser-based 3D preview, so you can inspect a model before downloading. New signups receive three free STEP downloads. The site says a typical reconstruction takes 30 seconds to two minutes. Jobs that rebuild less than 85% of a mesh fail without charge; 85% to 95% coverage produces a warning. The REST API runs jobs asynchronously and uses the same credits and plans as the web app.
The Free plan includes mesh conversions, reconstruction and preview with an account, and three signup downloads. Paid subscriptions begin with Maker at $19 a month for 30 STEP downloads monthly, a clean STEP header, and priority queue. Pro is $79 a month for 200 downloads monthly, while Team is $249 a month for 1,000 downloads monthly. Pay as you go costs $3030.00 USD once for 30 downloads, with credits that do not expire. The service says files are processed in Canada and deleted within 24 hours, except paid STEP files kept for 30 days for redownload.
