The Quick Measurement Tool is a lightweight but powerful addon for Blender that helps artists, modelers, and designers take fast and accurate measurements directly in the 3D Viewport.

It allows you to create measurement points, draw distance lines, and display live-updating text that always faces the camera (billboard effect). The lines and text use X-ray mode, so they remain visible through geometry.

Key features include:

• Add custom measurement lines with two draggable gizmos.

• Live updating distance values as you move the points.

• Billboard text that rotates automatically to face the viewport.

• Adjustable colors, thickness, and text size.

• Snap measurement points directly to the nearest mesh vertices.

• Measure the dimensions of any selected object instantly.

• One-click clearing of all measurement elements.

This makes it ideal for:

• Modeling workflows (checking proportions & distances).

• Level design (spacing and alignment).

• Technical visualization and presentations.
