better_erc can now measure the exact faces and edges in a component's 3D model while an engineer reviews its printed circuit board footprint. The Standard for the Exchange of Product model data (STEP), a common file format for mechanical part models, becomes more than a picture beside the pads. The reviewer can measure pin pitch, hole diameter, package height, angles, and distances between surfaces.
The tool places the model the same way KiCad does, over a 1.6 millimeter board with the pad copper shown. Two selected cylinders produce their axis-to-axis pitch; selecting a plane and an axis produces height; selecting the same circle twice records its diameter. Each result, such as a 1.270 millimeter pin pitch, is written into the review note with the drawing measurements.
That record matters when a library changes months later. A reviewer can compare a disputed footprint against the manufacturer's model and see which dimensions were actually checked. For a practical trial, use it on one connector where a wrong pin pitch or body height would scrap an assembled board, then decide whether the saved measurements are clear enough for another engineer to repeat the review.
