Btraces

Btraces is a pipe layout designer for planning a simple piping run before you buy parts or start fitting them. Draw the system on an interactive 2D canvas. Place straight segments, 90 degree elbows, tees, couplings, reducers, end caps, and valves. The material list updates whenever the drawing changes. Set length, nominal diameter, and material on each pipe. Geometry is stored in millimeters and can be shown in millimeters, centimeters, meters, inches, or feet. Runs stay horizontal or vertical. Grid snap and connection-point snap line a pipe end up with a fitting port. A mismatched diameter or material stays unconnected until you choose a compatible fitting or add a reducer. Pipes are grouped by material and nominal size. The list counts segments and fittings and reports centerline length. Estimated cut length appears only after you enter insertion depth on the connected fittings. A stock planner packs those cuts into standard lengths. Save a layout variant, compare centerline length and fitting counts, and export a PDF, a PNG, a CSV material list, or a JSON backup. Btraces plans geometry and parts. It does not certify installation, code compliance, or pressure.
