Description
Flash Cut 45 automatically miters 45° joints between perpendicular sticks in a single click. Works with any cross-section — boxes, C-channels, I-beams, and other complex profiles — via SketchUp Solid Tools subtract.

Select all 4 rails of a rectangular frame (picture frame, window frame, purlin frame) and click once — all 4 corners get mitered simultaneously. Sticks that don't reach the meeting point are automatically extended to fit.

Perfect for steel structure work, door/window frames, furniture frames, and any task requiring many 45° miter joints.
