Terms of service

Last updated: 12 November 2026

These terms apply when you use cadblockspro.com and shop.cadblockspro.com, browse the library, buy a block, or subscribe to the library. Please read them before you order. By using the site or placing an order you agree to them.

1. Who we are

CadBlocksPro is a trade name of DH INNOVATIONS LTD, 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom. DH INNOVATIONS LTD is the seller and the party you contract with. In these terms "CadBlocksPro", "we" and "us" mean that company.

You can reach us at support@cadblockspro.com.

2. What we sell

CadBlocksPro sells CAD blocks, which are ready-made drawings for use inside your own CAD drawings. Blocks are downloaded as DWG files (AutoCAD 2018 and 2010 formats) and as DXF files, and work in AutoCAD 2010 and newer. Blocks are drawn to ISO drafting conventions.

Everything we sell is digital. Nothing is shipped.

3. Working drawings, not engineering or legal advice

This section is important. Please read it carefully.

  • Our blocks are general-purpose drawing components. They are drawn to ISO conventions. They are not certified, approved or endorsed by ISO or by any other standards body or public authority.
  • They are not engineering, architectural or legal advice, and using them does not replace the judgement of a qualified professional.
  • Dimensions and details in a block are generic. They are not a specification for a particular manufacturer's product, unless the block says so.
  • You stay responsible for checking that a block suits your drawing, your project, your country and the standards and regulations that apply to it.

4. Browsing and previews

You can browse the library and view block previews online. Previews are for looking only and are not a licence to use the block files. We may set fair-use limits on browsing to protect the service.

5. Buying a single block

You can buy a single block for a one-time price. After payment you can download that block in the available formats. Delivery is electronic and starts as soon as payment is confirmed. A block you bought stays available to you to download again, and downloads of blocks you bought do not count towards your download limits.

6. Subscription to the library

  • A Full Access subscription gives access to the library for as long as it is active.
  • The first 7 days are free. You enter your card at checkout, nothing is charged today, and nothing is charged if you cancel before the 7-day trial ends.
  • When the trial ends, the subscription is charged at 16.90 USD a month or 89 USD a year, depending on the plan you chose at checkout.
  • The subscription renews automatically at the end of each month or year, and the payment method you gave at checkout is charged for the next period, until you cancel.
  • Cancel anytime from your account page. When you cancel, access continues to the end of the period you have already paid for, and no further payment is taken.
  • If we change the subscription price, we will tell you before the change applies to your next renewal.
  • Each subscription includes 1 seat, meaning 1 person.

7. Lifetime Access

Lifetime Access is a one-time payment of 349 USD. It gives you access to the library for as long as CadBlocksPro operates it, with no renewal and no further payment. It is subject to the same licence and fair-use download limits as a subscription, and includes 1 seat.

8. Download limits

To protect the library from copying, downloads are subject to fair-use limits. The free trial has a daily limit. Subscriptions and Lifetime Access have daily and 30-day limits. The limits that apply to you are shown in your account. Downloading the same block again, and downloading blocks you bought, never count towards the limits. We may adjust the limits to keep the service fair and secure.

9. Prices and payment

Checkout and payment run on Shopify at shop.cadblockspro.com, by card (through Shopify checkout, using Stripe) or by PayPal. Prices are shown in US dollars on the site. Your own currency may be shown at checkout, and the amount shown at checkout is the amount you pay. Taxes that apply in your country, including VAT where it applies, may be added at checkout.

Card and payment details are handled by the payment provider. We do not receive or store your full card number.

10. Your licence

When you buy a block or hold an active subscription or Lifetime Access, we give you a non-exclusive, non-transferable licence to use the blocks in your own drawings and projects, and in drawings and projects you prepare for your clients, including for commercial work.

You may:

  • insert, edit and adapt the blocks inside your own drawings and your clients' drawings;
  • deliver and publish finished drawings and projects that contain the blocks, in the normal way for that work;
  • keep using the blocks inside drawings you made while your licence was active.

You may not:

  • resell the block files, with or without changes;
  • share, redistribute or give away the block files, including to other people or businesses outside your own drawings and projects;
  • publish the block files themselves, as files or in any other library, marketplace, product or website;
  • share your account or sign-in with anyone else, or copy the library by automated means.

New downloads need an active subscription, Lifetime Access or a one-time purchase of the block.

11. Your account

You sign in to your customer account through Shopify with a code sent to your e-mail address. Keep access to your e-mail account to yourself. You are responsible for what is done through your account.

12. Fair use of the site

Do not use the site unlawfully, try to get around payment, download limits or access controls, overload or probe the service, or use it to build a competing collection of blocks. We may suspend access where these terms are seriously broken.

13. Intellectual property

The blocks, drawings, text, site and brand belong to CadBlocksPro or its licensors. Apart from the licence in section 10, no rights are transferred to you.

14. Refunds

Refunds are covered by our Refund Policy, which is part of these terms.

15. Availability and changes to blocks

We work to keep the site available and the blocks accurate, but we do not promise that the site will always be available or free of errors. We may add, update, replace or withdraw blocks. A block you downloaded earlier stays usable under your licence.

16. Our responsibility to you

We supply the blocks with reasonable care. Beyond that, and as far as the law allows, the blocks and the site are provided as they are, without any promise that they are fit for a particular project or purpose.

As far as the law allows:

  • we are not liable for construction defects, injuries, fines, penalties, stopped work, delays, lost profit or other indirect loss connected with the use of a block;
  • our total liability to you is capped at the amount you paid us in the 12 months before the event that gave rise to the claim.

Nothing in these terms excludes liability that cannot be excluded by law, and nothing removes rights that the law of your country gives you as a consumer.

17. Governing law

These terms are governed by the law of England and Wales. If you are a consumer, this does not remove the mandatory consumer rights you have under the law of the country where you live, and you may bring a claim before the courts of that country where that law allows it.

18. Changes to these terms

We may update these terms. The date at the top shows the current version. The version in force when you place an order applies to that order. For subscriptions, an updated version applies from your next renewal.
