Measure Better adds a measuring workflow to Blender through a custom "tape" side panel. In object mode it reads the dimensions of selected objects, and in edit mode it reports the length of selected edges, updating in real time as the selection changes. Measurements can be shown in metric units (meters, centimeters, millimeters) or imperial units (inches, feet), with automatic conversion between the two.
Beyond reading dimensions, the add-on lets you set them. Enter a specific size for the X, Y, or Z axis and apply it to selected objects or edges, sizing them to exact values without editing verts or faces by hand. An updated panel handles multiple objects or edges at once, with individual or multiple axis control buttons. Measurements can also be exported to a CSV file for documentation, planning, and collaboration.
For visualization, Measure Better can create 3D text objects that label measurements in the scene. You can set the color of that text, choose whether to include the unit suffix, and toggle all annotations on or off to keep the viewport clear. The panel lives under View3D > Sidebar > Tape.
