How do I set the scale of a dimension in a drawing using CAD Reader?

1. Launch the drawing in CAD Reader.
2. Use the Linear Measurement Tool to verify existing dimensions.
3. If the drawing isn’t to scale, locate and left-click on the Scale Tool in the toolbar.
4. Select two reference points that have a known actual length, then right-click to confirm the selection.
5. In the pop-up dialog, enter the true length between the selected points to define the accurate scale.
6. Click OK to apply the scale setting.
7. Recheck other known dimensions to ensure the entire drawing is correctly scaled.

Note: The measurement unit will align with the drawing scale. For example, dimensions in millimeters (mm) will yield results in square millimeters (mm²).
