Measurement rules control how the AI measures and counts on your drawings. They set the conventions behind every automatic takeoff, such as whether openings are deducted from wall lengths or how pipe runs are broken down. These settings apply org-wide to new takeoffs.

This is different from Measurement preferences, which set imperial or metric units per project. Measurement rules change what the AI produces, not how units display.

Open them from Settings under your organization name, on the Measurement rules page. Only organization admins can change these rules. Other members see the rules but cannot edit them.

The Region sets the defaults for every rule. Each region follows the measurement standards common to that area, so the AI counts the way estimators there expect.

Choose Global default to use the base defaults with no regional adjustment. Switching region changes the default for every rule below. Your individual overrides stay in place.

Rules are grouped into domains by trade, such as rough carpentry and framing, site utilities, or finishes. Each domain shows how many rules it contains and a customized badge counting any you have changed. Open a domain to see its rules.

Every rule states the question it answers, like how wall length is measured at a junction or how openings are handled. Many rules include a short explanation of why the convention exists and which standard it follows. Below each, the current Default for your region is shown.

Use the Search rules box to filter by keyword across questions, titles, and domains.

To change a rule, set its control to the value you want. A control may be a switch, a dropdown, a set of checkboxes, or a number field, depending on what the rule accepts. Your choice saves automatically and a Customized badge appears.

Setting a rule back to its default removes the override. You can also click the reset icon next to a rule to return it to the regional or base default.

When you have one or more overrides, a Reset all overrides button appears at the top of the page. Use it to return every rule to its regional or base default at once. A confirmation appears first because this cannot be undone.

Changes apply to new takeoffs going forward. Existing takeoffs keep the rules that were in effect when they ran. To learn how takeoffs use these rules, see AI takeoffs.
