Understanding Scale Locking in AutoCAD on Mac

Locking the scale of a layout viewport in AutoCAD is vital to ensure that your drawings maintain accuracy and consistency during the drafting process. This article will guide you step-by-step on how to effectively lock the scale in AutoCAD on a Mac environment.

Steps to Lock Scale in AutoCAD on Mac

1. Access Paper Space
   Before you can lock a viewport scale, ensure that you are in the paper space of your drawing. Look for the UCS icon, or simply move your crosshairs to confirm that you are not in model space.

2. Select the Viewport
   Click on the border of the layout viewport you wish to lock. The selected viewport should become highlighted, indicating your selection.

3. Open the Viewport Lock Option
   Once you have selected the viewport, locate the “Lock/Unlock Viewport” button in the options available on the interface. This is typically located in the toolbar or under the right-click context menu.

4. Lock the Viewport Scale
   Click on the “Lock/Unlock Viewport” button. This action will lock the scale of the viewport you’ve selected, preventing any accidental alterations to the viewport’s scale settings.

5. Confirm the Locking Action
   After locking, you may want to right-click on the viewport border again to ensure that the option indicates ‘Display Locked: Yes.’ This confirms that the viewport scale has been effectively locked.

Adjusting the Viewport Scale

Should you need to change the scale before locking it, follow these steps:

1. Right-click the Selected Viewport
   With the viewport selected, right-click to access the context menu.

2. Choose Properties
   Select the ‘Properties’ option from the right-click menu. This will open a properties palette that contains various settings related to the viewport.

3. Modify Scale Settings
   If the viewport is currently locked, you may need to unlock it first by changing the “Display Locked” setting to No. Once unlocked, you can adjust the ‘Standard Scale’ from the properties palette.

4. Re-Lock the Viewport
   After making any necessary scale adjustments, proceed to lock the viewport again by following the locking steps outlined earlier.
