DrH/Pricing
DrH is not a one-off download that ages badly. Autodesk ships a new host year every spring, and the library moves with it. Pro is $100 per user per year for one engineer. Max is $375 a year for a firm, as a fixed pack of 5 users. Both cover everything published in that year — including tools you ask for.
Everything you need to run tools you already own.
.addin packages from a folder.addin sidecar detectionWindows installer. Nothing to sign up for.
The manager, plus a library that keeps growing under it.
Invoiced yearly, cancel by not renewing.
For firms standardising on one set of tools. A fixed pack of 5 users, which works out at $75 per user per year.
Exactly 5 users. Tell us the hosts you run.
Most add-in packs give you a fixed set and leave you to work around the gaps. DrH is built the other way round. The library is the product, and it grows because Pro users point at the tedious part of their week and ask for it to go away.
Write what you do by hand today and how often. You do not need to specify an API, a command name or a dialog layout.
Every request gets a straight answer: it is being built, it needs narrowing, or it is out of scope and here is why.
Accepted tools are published to the library. Press Update in the DrH panel and the new command is there — no installer, no IT ticket.
Unless you ask for it to stay private, an accepted tool joins the shared library. The library you buy into is the one other engineers keep improving.
A new tool is published against the host years you are actually on, matched to the right runtime channel, not just the newest release.
On Max a requested tool can be published to a private feed that only your office can see.
A longer term is billed once, up front, and the rate is locked for the whole of it — including through any list price change. There is no monthly option on any tier.
| Term | Pro, per user | Max, 5-user pack |
|---|---|---|
| 1 year | $100 | $375 |
| 2 years | $175 save $25 | $650 save $100 |
| 3 years | $250 save $50 | $1,000 save $125 |
One named person, on as many workstations as that person works at. If an engineer has a desk machine and a laptop, that is one licence, not two.
Pro if you are buying for yourself: $100 a year, one named user. Max if you are buying for an office: $375 a year for a fixed pack of 5 users. Worth knowing that four Pro licences cost $400 while the five-user Max pack costs $375 — if you are close to five people, Max is both cheaper and better suited.
The private feed, the central distribution and the seat console only make sense for a group, and they carry setup work regardless of size. For fewer than five people, Pro is the honest fit.
No. Every tier is invoiced yearly in US dollars. If you want to spread the cost, a two- or three-year term is billed once up front for less than paying year by year, with the rate locked for the term.
Pro includes 1 support email a week; Max includes 3 a week across the whole licence. Unused requests do not roll over. The quota is there to keep replies fast, not to run a meter on you — if something is genuinely broken it gets dealt with regardless of the count.
Max is a fixed pack of exactly five users. If you need more seats than that, get in touch before buying and we will work out the right arrangement for your team.
You can request anything. What gets built is what fits the library: a repeatable task inside Civil 3D, Revit or Navisworks that more than one person would use. Anything too specific to one project is better as a private Max tool.
It depends entirely on the ask. You will get a realistic estimate in the reply rather than a queue position, and small routines usually land far sooner than anything that needs a new dialog.
Tools already installed keep working — nothing is switched off on your machine. What stops is the flow of new tools and updates, until the licence is renewed.
By invoice, in USD, yearly. Ask for a licence and an invoice comes back with the payment details on it.
No. Importing and running your own packages is free and stays free. Pro is about the maintained library and the requests.
Support for a new host year is part of the licence, not a paid upgrade. Library tools are republished against the new year as it becomes available.
Every paid licence comes with a 14-day money-back guarantee. If DrH is not what you expected, say so inside the first two weeks and the invoice is refunded in full — no reason required and no forms to fill in.
The window opens the day your payment clears and runs for 14 calendar days. Ask inside it, in writing, and the refund is processed — you do not need to justify the decision.
The refund goes back to the account the payment came from, for the full invoiced amount. Expect it to land within 5 to 10 working days depending on your bank; any transfer fees charged by your own bank are outside our control.
Two- and three-year terms are covered by the same 14 days from the up-front invoice.
A licence year is not refunded pro rata once the window closes; it simply runs to its end date. Nothing is switched off on your machine — installed tools keep working, and you are free to not renew.
Email support@dr-h.uk with the invoice or payment receipt number. A refund is confirmed by reply, and the licence is closed on the same day.
The DrH manager itself is free, so there is nothing to refund there. Try it against your own hosts and your own packages before buying a year — that is what it is for.
DrH is a small operation, and the data position matches that. We hold what is needed to answer you and to run your licence, and nothing beyond it. This site carries no analytics, no advertising and no third-party trackers.
The request form takes the request type, your email or phone, the host and year, and your message. A request sent from the DrH panel may also include the user name, PC name, MAC address, licence key and build number, because those identify the seat being licensed or debugged.
It is used to reply, to issue and maintain your licence, and to reproduce faults. It is not sold, rented or passed to anyone for marketing, and you will not be added to a mailing list by filling in the form.
No tracking or advertising cookies are set. The only thing kept in your browser is your theme choice, stored locally on your own machine, which never reaches us.
The site runs on Cloudflare Pages, and form messages are delivered to our support mailbox through the mail provider wired to it. Those providers keep standard request and delivery logs on our behalf. Cloudflare also tells the site which country you are visiting from; that is used only to show prices in your currency and is not stored.
Correspondence is kept while your licence is live and for as long as it is useful to support you. Invoices are kept longer because accounting rules require it.
Ask at support@dr-h.uk for a copy of what is held against your name, a correction, or deletion, and it is dealt with. Billing records that must be retained for tax are the one exception.
Ask for a licence, request an invoice, or send a tool idea and see what comes back. All three go to the same place.
