Generate dimension annotations as real 3D geometry with OCCT in Bitbybit - linear, angular and ordinate dimensions, plus labelled pins. Because the dimensions are geometry rather than an overlay, they live in the scene, scale with the model, export with it, and stay correct when a parameter changes. That makes them useful for technical previews in a configurator, for drawings generated straight from the model, and for teaching material where the measurement has to be visible. These pages cover each dimension type, its inputs, and how to control text size, arrows and placement.
