Measure and Scale is a very simple addon that allow you to Measure between any two vertices and uniformly scale the entire object to match that measurement. This addon provides the following intuitive workflow:

• Select a vertex on your mesh to begin measuring then simply hover over (snap to) a second vertex to see the live distance displayed between the two points.
• Right-Click anytime to cancel the operation or Left-Click the second vertex to confirm the measurement and proceed to scaling.
• A dialog box appears showing the measured distance. Enter the dimension you want that segment to be. The entire object will be uniformly scaled to match your target dimension, with the scale automatically applied.
• Supports Metric (m, cm, mm) and Imperial (ft, in) units.
• Find it: 3D Viewport > Sidebar (N-Panel) > Item Tab > Measure and Scale

• When I previously created clay renders, I found it a bit inconvenient. Merging all objects into a single material often interfered with certain transparent objects, like virtual camera apertures. However, this add-on selectively turns only the intended parts into clay-like white, while keeping the important details intact — almost like AI magic. It's truly amazing. Thank you so much for creating and sharing such a great add-on. It looks like value nodes are remaining as residues. 4.5
