Scale in Title Block Not Updating
Normally, when changing the scale from the layout settings, the scale attribute in the title block is updated. However, there are cases where the drawing scale does not update as expected.

Cause:
No matching rule has been set for the scale.
Solution:
[1] Open [Options] in the [Menu] or [Tools] tab.

[2] Go to [System], then click [Set Matching Rule].
[3] In the list, check if [Attribute Name] → [Scale] exists.
If the item in the red box below is present in the list, follow these steps in order:
Regenerate the 3D data and update the drawing.
If the display still does not change, try adding a dummy projection view and check if it updates.
[4] If Scale is not listed, create a new entry.
