Help & setup

> for SkuEstimator on SketchUp® Pro 2026 · Windows

Install, activate and produce your first estimate in a few minutes. Short steps, exact menu names.

1. Requirements

  • SketchUp Pro 2026 on Windows 10 or 11. On an older SketchUp, or on a Mac, the extension shows a message and does not load.
  • Components with attributes. SkuEstimator reads the dynamic-component attributes on your components, not the geometry. The core ones are Itemcode, Name, Supplier, Qty and Price. It also uses Category, Usage, Unit, Measure, Cost and Weight when they are there. See Getting your components ready.
  • An internet connection to activate. After that the licence is checked in the background, and SkuEstimator keeps working for 30 days without a connection.
  • Microsoft Edge (it ships with Windows) is used to save PDFs. If it isn't available, SketchUp's print window opens instead.

2. Install

  1. Download SkuEstimator (.rbz) from the welcome page you see after checkout, or any time from your account page (enter your licence key, then Download SkuEstimator). The download is for subscribers only, so you need a trial or paid subscription first.
  2. In SketchUp, open Extensions › Extension Manager, click Install Extension and choose the .rbz file.
  3. The extension appears in the Extension Manager as SkuEstimator (by Modular Buildings Australia Pty Ltd), and its commands are under Extensions › SkuEstimator.
  4. Choose Extensions › SkuEstimator › Open SkuEstimator…. Until this computer is activated, only the licence window opens (see the next section). After that it opens the workspace, and the first time the setup wizard walks you through your company details, your attribute names and your default document.

3. Activate your licence

  1. Open Extensions › SkuEstimator › Licence…
  2. Paste your licence key (it looks like SKU-XXXXX-XXXXX-XXXXX-XXXXX). It is on the welcome page you saw after checkout and in your purchase email.
  3. Click Activate. The workspace opens. On a free trial, exported documents carry a TRIAL COPY watermark until your first payment; on a paid subscription there is no watermark.

No key yet? The licence window has Start free trial and Buy now buttons that open the pricing page.

Two computers per licence. If the key is already active on two computers, SkuEstimator lists each one with the date it was last seen and a Release button. Release one to activate here instead.

Checking your licence

Choose Licence… again at any time. It shows your status and offers Manage billing (card, invoices, cancel), Release this computer, and, during a trial, End trial & pay now. The status also shows as a badge in the workspace header, for example Licensed or Trial.

Ending the trial early

To remove the trial watermark before the 3 days are up, choose End trial & pay now in the licence window or on your account page. Your card is charged A$29 + GST (A$31.90 in Australia) straight away. In the licence window the watermark is removed at once; from the account page it goes the next time SkuEstimator checks your licence (open Licence… or restart SketchUp; otherwise within 6 hours). If the payment is declined, your trial carries on unchanged.

Working offline

SkuEstimator checks your licence in the background: about a minute after SketchUp starts, then every 6 hours. It never makes you wait. If it can't reach the server, your licence stays valid for 30 days from the last successful check. After that the badge reads Licence needs to reconnect. Reconnect to the internet and it refreshes at the next check.

Without a licence

Without an active trial or subscription, SkuEstimator shows only its licence window; the workspace, Live Cost and the other tools stay closed. Licence…, Save Diagnostics Report…, Back Up Data… and Restore Data… always work. Your models and settings are never deleted, and everything is back as soon as you activate again.

Your key is stored on your computer, encrypted to your Windows account.

4. Your first estimate

Setup wizard

The first time the workspace opens, a short wizard sets you up. Each step is saved only when you click Next, and Skip for now closes it at any point. Run it again any time from Extensions › SkuEstimator › Setup Wizard… or the Run setup wizard button in Build › Your Details.

  1. About you: your name (or business name), phone, email and delivery address, so suppliers know who to reply to. Businesses can open For businesses to add an ABN, website, logo and bank details for client quotes.
  2. Your components: choose Use my open model to match your own attribute names (for example PartNo or UnitCost) to SkuEstimator's fields, with a live preview of the first three rows, or Try the sample model first.
  3. What do you want to do?: tick Cost my project, Get prices from suppliers, Order materials and/or Quote a client. Build then offers just those documents (Cost Summary, Price Request, Materials Order, Customer Quote). Picking Quote a client also asks for your markup. Tax (GST, VAT or sales tax) starts off; switch it on for any document in Templates.
  4. AI assistant (optional): paste your own OpenAI or Anthropic key, or skip it. Everything else works without it.
  5. Ready: Open Build selects your first document and runs Preview.

The sample model

The sample model is a fictional 6 × 4 m carport frame with made-up suppliers and prices. It's the quickest way to see the whole workflow.

  1. Choose Extensions › SkuEstimator › Open Sample Model… If your current model has unsaved changes, it asks first, and then builds the sample in a new model. Your current model stays open and unchanged.
  2. The workspace opens on the Build tab (Build › Build Documents).
  3. Under Template, choose Sample Cost Summary, then click Preview. The cost summary should total 1,417.68 ex GST (the sample is Australian, so it shows GST).
  4. Click Save PDF…, choose where to save, and the PDF opens when it's done. Print… opens the Windows print dialog instead.

Opening the sample also adds any sample records you don't have yet: sample suppliers and a sample client, catalogue items, the Sample Cost Summary template, pack rules, a linked screw rule and a delivery charge, all marked “(sample)”. It never overwrites a record you already have, so a sample record you've edited keeps your changes.

5. Getting your own components ready

Each component you want counted needs dynamic-component attributes. At minimum, give it an Itemcode, Name, Supplier, Qty and Price. Add Unit and Measure for items bought by length or area, and Category to group items and assign colours. The sample model's components are a complete working example to copy from.

  • Already using your own names? If your components say PartNo, Vendor or UnitCost, you don't have to rename them. Map them once in step 2 of the setup wizard. Editing a mapped value from SkuEstimator updates your own attribute rather than adding a second one.
  • Colour placeholders. Put ?? in an Itemcode (for example RS76??). Once you assign a colour to that component's category in the Colour Selector, the placeholder becomes the three-letter colour code.
  • Imported library components. Components imported from a library .skp file can arrive wrapped in an extra shell. Choose Extensions › SkuEstimator › Unwrap Imported Components to explode those shells. It only touches a shell that holds exactly one component with the same Itemcode, and Edit › Undo reverts it in one step.
  • Auto-unwrap. Auto-unwrap Imported Components in the same menu does this automatically for components you import from then on. It's off by default and shows a tick when on.
  • Lots of components to set up? Select them and use Attribute Suites (right-click › SkuEstimator › Add attribute suite) to add the Standard suite (Name, Type, Length, Qty and Unit) in one step. To add Itemcode, Supplier and Price as well, build your own suite under Catalog › Attribute Suites. Editing a whole library of .skp files in bulk is the Component Library (Pro), part of SkuEstimator Pro.

6. New computer, backup & restore

Back up

Choose Extensions › SkuEstimator › Back Up Data… and pick where to save. You get one .json file containing your templates, suppliers, clients, rules (pack rules, linked items, standing charges, fail safes), catalogue items, your details and custom colours.

A backup does not include:

  • AI API keys, because they're encrypted to one Windows account. Re-enter them after restoring.
  • Window and tab state, or logs.
  • Logo image files. Only their file path is kept, so copy the image across as well.

Anything specific to one job (edits in the Build table, colour assignments) is saved inside that job's .skp file, so copy your model files across as well.

Restore on the new computer

  1. Install SkuEstimator and activate it.
  2. Choose Extensions › SkuEstimator › Restore Data… and pick the backup file.
  3. Check the record counts it shows, then click Yes. Records in the backup replace records with the same name, and records that exist only on this computer are kept.
  4. Close and reopen the workspace to see the restored data.

Your data is saved automatically before a restore (to a backups folder inside the data folder), so a restore can always be undone.

Freeing a seat

Your licence covers 2 computers. To move it, do one of these:

  • On the old computer, choose Licence… and click Release this computer.
  • On the account page, enter your key, click Show my computers, then Release the one you no longer use.
  • Activate on the new computer. If both seats are in use, you're asked which one to release.

7. Troubleshooting

Item codes show ??

The component uses a colour placeholder and no colour is assigned to its category yet. Open Tools › Colour Selector in the workspace (or Extensions › SkuEstimator › Colour Selector…), select the category and pick a colour. Categories come from the Category attribute by default.

My PDFs say “TRIAL COPY”

You're on the free trial. The watermark goes when your first payment goes through: at the end of the trial, or straight away with End trial & pay now.

My PDFs say “UNLICENSED COPY”

Your licence can't be confirmed right now. The badge in the workspace header tells you why:

  • Licence needs to reconnect: you've been offline for more than 30 days. Go online.
  • Check your computer clock: the Windows date has been set backwards. Correct it.

Payment overdue is different: exports stay clean for up to 7 days while payment retries. Update your card through billing before then or SkuEstimator locks.

“PDF not saved” and the print window opened

Save PDF… uses Microsoft Edge in the background. If Edge can't be found, or doesn't finish within 60 seconds, the print window opens instead. Choose Microsoft Print to PDF as the printer to save your document.

The Preview is empty

Click Refresh, then Preview. If it's still empty, the model has no components with attributes for the selected template. Try the sample model to confirm everything works, then check your components' attributes. If they use your own names, map them in the setup wizard.

Menu items are greyed out

Most commands need an open model. Open Sample Model…, Licence…, Save Diagnostics Report…, Back Up Data… and Restore Data… are always available.

Sending us a support report

Choose Extensions › SkuEstimator › Save Diagnostics Report… and attach the .txt file it saves to your email. It contains:

  • the extension, SketchUp, Windows and Ruby versions
  • which optional features are switched on
  • how many records are in each data store
  • the last 150 lines of the error log, with your Windows user folder and any email addresses blanked out

It contains no customer records, prices, templates or keys.

Where your settings live

Templates, suppliers, clients, rules and your details are stored in %APPDATA%\SkuEstimator\. The error log is in its logs folder. Use Back Up Data… rather than copying this folder by hand.

8. Billing & cancelling

  • Price. SkuEstimator DIY is A$29 per month plus GST (A$31.90 inc. GST). SkuEstimator Pro (A$299 per month plus GST) is coming soon. With the 3-day free trial you're charged when the trial ends unless you cancel before then; with Pay now at checkout, or End trial & pay now later, you're charged straight away.
  • Manage billing. On the account page, enter your licence key and click Manage billing. This opens Stripe's secure portal, where you can update your card, download invoices or cancel. You can also get there from SketchUp: Licence…, then Manage billing.
  • Cancelling. Cancelling takes effect at the end of the period you've paid for, and you keep full use until then. See the Terms.
  • After cancelling, once the paid period ends SkuEstimator shows only its licence window. Your models and data are untouched. Resubscribe from the account page to keep the same key, and everything comes back.
  • Lost your key? Use the Lost your key? form on the account page and we'll email it to you, or email us from your billing email address.
