Terms of use
Last updated: 05/11/2026
1. The service
X PROF 66 is an online service for design offices and contractors: measuring CAD drawings (DXF and DWG), analysing PDF and image drawings, reading rooms into a design, quantity takeoff, bills of quantities, sheets and issue documents, and reports.
2. Your account and office
Whoever creates the account becomes the owner of the office and is responsible for its members (whom the owner invites), what they upload, and keeping the password secret.
3. Plans and the trial
Every office starts with a trial; after it, a plan has to be activated to keep adding and changing things. The plans, their prices and their limits are those on the pricing page. Online payment is not available yet, and for now plans are activated by the service’s administration. When a plan ends, or the office moves to a smaller one, nothing is deleted: the data stays available to view and export, and only what the plan no longer includes is refused.
4. Your files
The files and data you upload belong to your office. You allow us to store and process them as far as needed to provide the service, including sending some of them to AI providers as the privacy policy describes. You confirm that you have the right to upload your clients’ drawings and have them processed this way.
5. Results are an aid, not an approval
Quantities, schedules and drawings produced by the service, especially what AI extracts or what is worked out from a drawing’s layers and shapes, can contain mistakes. A qualified engineer reviews them before they are used for pricing, construction or a contract. Every sheet is a draft until the office owner records the responsible engineer’s approval; the service approves no drawing by itself and sets no market prices. Specification clauses and catalogue texts are drafts to adapt to your project, and no authority has approved them.
6. Acceptable use
Do not use the service to upload what you have no right to upload, to try to reach other offices’ data, or to disrupt the service.
7. Changes
We may change these terms or the privacy policy. After any substantial change we ask you to accept again before you continue.
