Pro Symbol Library Licence (CXL-1.0 Licensed)
Updated November 7, 2026
This licence applies to the paid Pro symbol libraries sold on cadxchange.net (for example ANSI/IEEE 315 Pro): DWG files delivered by download, in AutoCAD 2018 and AutoCAD 2010 format. It is part of the CADXChange library terms CXL-1.0 (Licensed). The licence record in the LICENSE-RECORD.txt of every ZIP and in your account names the licence type and number. There are two types, Individual and Organisation; this page covers both.
1. What the licence covers
Every section of the Pro library as it is sold, in both file formats. The free library that the Pro library extends (for example the free ANSI/IEEE 315 library) is not part of the purchase: it stays free under the library terms, and you may keep using it with or without a licence. Sections added later to the same Pro library are included for current licence holders; a new major edition may be sold separately.
2. Who holds the licence
Individual: the licence belongs to one person, the buyer. It does not cover a team or a company, even if the buyer works for one.
Organisation: the licence belongs to one company. How many of its people may use the library is set by the seat band that was bought (up to 25, 100, 250 or 1,000 people, or no limit on people); the people counted are the employees who actually use the files. A larger number of users needs a larger band; the licence can be upgraded at any time by paying the difference. Contractors, freelancers, subcontractors and clients are not covered. Subsidiaries and other companies are covered only if they are named in the licence record.
3. What you may do
Use and modify the symbols in your own projects, including commercial ones and drawings you deliver to clients. Pass on finished drawings that contain them. Keep the files on your own computers and backups; under an Organisation licence also on the company's servers and network drives, shared among its employees up to the seat band, and in its templates, tool palettes and company standards.
4. What you may not do
Give copies of the library, a section or a part of it to anyone outside the licence holder, share your download, or publish it. Clients and contractors receive finished drawings only.
Redistribute the library or a substantial part of it, in original or modified form; sell it; add it to another block library or download site; offer it as a template or sample drawing set; or build it into a software product, plug-in or online service that you distribute. Do not remove the terms line and the licence record from the files. If you publish our symbols or screenshots of them (tutorials, articles, videos), credit "CADXChange" and link to cadxchange.net.
5. Symbols are drawings, not standards or engineering advice
The symbols are drawn by CADXChange following the conventions of the published standard. They are not copies of the standard, they are not certified, and they are provided as is, without warranty of any kind. IEEE, ANSI, ISO, IEC and other names belong to their owners; the libraries are not affiliated with them. Check every drawing against the standard or the legend you work to; the symbols do not replace the design and approval of a qualified engineer.
6. Delivery, duration and refund
You download the files from your account while you are signed in; the number of downloads per day is limited. The licence is perpetual for the library you bought and stays under the terms version it was bought with. A refund is possible within 14 days of the purchase as long as nothing has been downloaded; see the refund policy at /legal/refund. All rights not expressly granted are reserved.
