Type exact values in the inspector as 6' 2", 27 1/8 or 84 (inches).
All wall types snap end-to-end in a straight line, or butt against any point on another wall’s face at 90° without a connector. While dragging, blue markers show join points and a green SNAP marker shows the join being used. Hold Alt to place freely. Balance beams snap end-to-end or at 90°.
Path & checks rejects centre-line paths into temporary panels, even beyond a target. A separate audit checks nine target-face samples from reachable 6″ floor-grid points at the configured eye height. Configured green range surfaces are not certification; sampling can miss conflicts, and ricochet, penetration and ballistics are not modeled. Qualified range-safety review is required.
