Carpenter Tools vs Carpenter Pro Calc

Every answer comes with a drawing. Change the wall length and the studs move on the plate. Change the rise and the stair redraws with its risers, treads and stringer, checked against common code limits. What you measured is in black; what you cut and buy is in red. Type it like you read the tape: feet, inches and fractions on a keypad built for lengths. • Wall framing, rough openings, rake walls, stud layout and square checks • Stairs, common rafters, hips and valleys • Decks, fences, concrete slabs, footings and post holes • Sheathing, drywall and flooring • Baseboard, casing, miters and crown, cabinet boxes, face frames and shelf pins • Tape calculator with memory, cut lists, board feet, triangles, arcs and plan scales Feet and inches, decimal feet or metric, on iPhone and iPad. Share any drawing as a picture with its numbers. Always check your local code before you cut.
