Dimensioneer is a Blender add-on that lets you place clear, customizable measurements directly in the 3D Viewport, so you can document models without bouncing to another app. Add live dimensions to full object bounding boxes or measure selected points and edges in Edit Mode, then adjust colors, text, line styles, and display settings for clean, readable technical views. Whether you’re laying out booths, checking product sizes, or preparing presentation screenshots, Dimensioneer keeps your measurements attached to the model and updates them as your design changes.
