To change the units to millimeters (mm) in Autodesk Inventor 2024, you need to adjust both the Document Settings and the Styles and Standards. Here's how:
1. Change Document Settings:
- Go to the Tools tab.
- In the Options panel, click Document Settings.
- In the Document Settings dialog box, select the Units tab.
- In the Length section, change the units to Millimeter (mm).
- Click Apply and then Close.
2. Change Styles and Standards:
- Go to the Manage tab.
- In the Styles and Standards panel, click Styles Editor.
- In the Style and Standard Editor dialog box, expand the Standard section in the browser on the left.
- Select the active standard (e.g., "Default (ANSI)").
- On the right pane under "Units", change the Linear Unit to Millimeter (mm).
- Click Save to save the changes to the style.
- Click Done to close the Styles Editor.
Explanation and Important Considerations:
- Document Settings: Changing the units in the Document Settings affects the current document. All new dimensions and measurements will be displayed in millimeters.
- Styles and Standards: Changing the Styles and Standards affects the drawing templates and default settings. This ensures that new documents you create will use millimeters as the default unit. If you don't modify the Styles and Standards, new documents might still default to inches or another unit based on the template used.
- Active Standard: Make sure you are modifying the active standard used by the document. You can confirm the active standard under the "Standard" tab within "Document Settings".
- Existing Dimensions: Changing the units won't automatically update existing dimensions. You might need to manually edit or redefine dimensions to reflect the new units correctly.
- Templates: Modifying the default template will ensure new files use mm.
