Feature comparison
| Free | Basic | Pro Team | Ultra | |
|---|---|---|---|---|
| Storage | 1 GB | 4 GB | 10 GB | 20 GB |
| Member seats | Just you | Just you | 3 seats | 10 seats |
| No ads | ||||
| Analysis tools (measure, section, x-ray, first person) | ||||
| Password-protected share links | ||||
| Model health checks: automatically flag members that are over stock length, over transport or lifting limits, use non-standard sections, or share a mark with a differently shaped member | ||||
| Part drawings: open any single part and get a dimensioned flat drawing on the spot — outline, thickness, hole diameters and hole-to-edge distances; measure anything that is not dimensioned by clicking two points, and what you measure stays for the next person | ||||
| Clash and clearance checks: find members that collide, plus the spots too tight to fit a bolt or reach with a welding torch | ||||
| Erection sequence animation: the building assembles itself in site order — columns with bracing frame by frame, then beams, roof purlins and wall girts; scrub and change speed to walk clients and crews through the erection | ||||
| Automatic route roaming: plan a route and camera height from the top view, then play and save repeatable model walkthroughs | ||||
| AR preview: view a selected component or the whole model at true size or with adjustable scale | ||||
| Model version comparison: put two revisions side by side with added, removed, moved and re-sectioned members colour-coded, and export the difference list | ||||
| Quantity take-off: totals by section, grade and length — count, weight and paint area — exported as a spreadsheet | ||||
| Model markups and issue tracking: raise a question on a member, assign it to a teammate, track it to closure, and export in an interchange format other tools can open | ||||
| Projects and component progress: group models into projects and track components by fabrication and installation status; colour by status in the engineering view and isolate the ones not yet fabricated or installed | ||||
| Check report export: turn check results into a report you can send straight to the client, set your own stock lengths, lifting capacity and transport limits as the check standard, and run checks across several models at once | ||||
| Component QR codes and printable labels: generate a QR label for the selected component to print and use | ||||
| Brand customisation: your company name and logo on the loading and share pages |

FAQ
- Is the permanent Basic plan really permanent?
- Yes. Once granted it has no expiry date and stays active for as long as the service runs — nothing to renew, and it never falls back to Free.
- Will my models be deleted when my plan expires?
- No. Your quota drops back to the Free tier and you cannot upload new models, but existing models and share links you already sent stay viewable through the grace period. Renewing restores everything immediately.
- How do I pay?
- Plans are activated offline for now: contact us to confirm the tier and term, and we will enable it on your account. Online payment is not available yet.
