Terms and Conditions

Last updated: 15 August 2026

1. Who these terms are with

These terms govern the supply of AutoLISP programming services by WWW.CAD-RESOURCE.COM LIMITED (company number 06121953, registered office 320 Firecrest Court, Centre Park, Warrington, WA1 1RG; VAT number 903445739), trading as cad-lisp.com — referred to below as “we”, “us” and “our”. “You” means the person or organisation commissioning the work.

By asking us to quote for or carry out work, you accept these terms.

2. What we do

We write, extend and repair AutoLISP programs for use with AutoCAD®, to your brief. Specifically:

• writing new routines from scratch;
• adding functionality to routines you already have;
• diagnosing and repairing routines that have stopped working.

3. Quotations

To quote, we normally need a written description of what you want and a drawing file, an existing routine, or both.

A quotation is an invitation for you to place an order, not a binding offer. No contract exists until we confirm in writing that we accept the work. We may decline work, and we will say so promptly rather than leave you waiting.

Quotations are based on the information and files you give us. If what you need turns out to be materially different from what was described, we will tell you before doing further work, and give you a revised price to accept or decline. We will not carry out chargeable work you have not agreed to.

A quotation is valid for 30 days unless we say otherwise.

4. How the work proceeds

1. You send us your brief, with any drawing or program files we need.
2. We tell you whether we can do it, and quote a fixed price.
3. We write the program.
4. We demonstrate it working before you pay anything, by making a screen recording available to you.
5. If you are happy, you pay the quoted price.
6. On receipt of cleared payment, we make the program files available to you to download.

5. Files you send us

You confirm that you are entitled to send us the files you send, and that doing so does not breach anyone else's rights or any obligation of confidence you are under.

We treat your files as confidential. We use them only to quote for and carry out your work, we do not share them with anyone else, and we do not use them as examples or samples without asking you first.

6. Intellectual property

When you have paid in full, the program we have written for you is yours. All intellectual property rights in the program files we deliver pass to you on receipt of cleared payment, and you may use, change, copy and distribute them however you wish, without further reference to us.

Until payment is received in full, everything we have produced remains ours. The demonstration recording is provided so you can see the program working before deciding whether to buy. It does not give you any right to the program itself, and you may not use, reproduce or attempt to reconstruct the program from it.

Nothing in this clause transfers any right in your own files, which remain yours throughout.

7. Price and payment

Prices are quoted per job, as a fixed sum, in the currency stated. Prices exclude VAT, which will be added where it applies.

Payment is due before delivery. We will send you a link to pay. The program files are released to you once payment has cleared.

8. Delivery

We deliver electronically, by making the files available to you to download. We do not supply anything on physical media.

When we deliver, we will confirm in writing the AutoCAD® version and configuration in which the program was written and demonstrated. That is the environment our warranty in clause 9 applies to.

We will give you an indication of timing when we quote. We will keep you informed if anything changes, but times given are estimates and are not guaranteed unless we have agreed otherwise in writing.

9. What we promise, and what we don't

We warrant that the program will perform substantially as shown in the demonstration recording, in the AutoCAD® environment recorded at delivery under clause 8.

That warranty does not cover:

• changes you or anyone else makes to the program after delivery;
• a different version of AutoCAD®, or a different configuration, from the one recorded at delivery;
• drawings materially unlike those you gave us to work with;
• anything caused by other software, add-ins or customisation on your system.

AutoCAD® and AutoLISP® are the products of Autodesk, Inc. and we have no control over them. We are not responsible for changes Autodesk makes to AutoCAD® or to the AutoLISP® language that affect a program after delivery. We are happy to quote separately for updating it.

10. Your responsibility to test and to back up

AutoLISP programs act on your drawings. You must test what we deliver on copies, not on live production drawings, before you rely on it, and keep your own backups. We are not liable for loss or damage to drawings or data where you have not done so.

11. Our liability

Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be limited.

Subject to that, and to clause 9:

• our total liability in connection with any job is limited to the amount you have paid us for that job;
• we are not liable for loss of profit, loss of business, loss of contracts, loss of anticipated savings, or for loss or corruption of data, in each case whether direct or indirect;
• we are not liable for any loss that was not reasonably foreseeable when the work was agreed.

12. Confidentiality

Each of us will keep the other's confidential information confidential, and use it only for the purpose it was given. This does not apply to information that is already public, that we independently hold, or that we are required to disclose by law.

13. If you are buying as a consumer

If you are buying as an individual rather than for a business, you normally have 14 days to cancel a distance contract. Because we write each program specifically to your brief, that right does not apply once we have begun work, and by asking us to start you agree to that and acknowledge you will lose the right to cancel.

This does not affect your legal rights if what we deliver is faulty or not as described.

14. Cancellation

You may cancel before you pay, at no charge — that is the point of demonstrating the program first. If you cancel after we have accepted the work but before delivery, nothing is payable, and nothing is delivered.

15. General

These terms, together with the quotation we have accepted, are the whole agreement between us on the work in question.

If any part of these terms is found to be unenforceable, the rest continues to apply.

We may update these terms. The version that applies to your job is the one published when we accepted the work.

16. Governing law

These terms and any dispute arising from them are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.

17. Trademarks

AutoCAD® and AutoLISP® are registered trademarks of Autodesk, Inc. cad-lisp.com is not affiliated with, endorsed by, or sponsored by Autodesk, Inc. We refer to those products only to identify the software our services are written to work with.
