Rafter Tools

Rafter Tools is an android app with functions to calculate complex roof framing angles that other roof framing calculators can't and don't offer. Calculating common rafters with a construction calculator is fairly easy, but to be a master carpenter you need more roof framing angle information then the construction calculators offers. With the Rafter Tools android app you'll be able to calculate all of the complex angles for roof framing. The app's main screen uses a left swipe motion to display all of the different calculators.See my Roof Framing Geometry Blog for A Complete list of the 39+ calculators in Rafter Tools for Android.http://sbebuilders.blogspot.com/2013/07/rafter-tools-for-android-version-256.htmlCurrent version 2.62 functions supported:Irregular Hip Rafter function With UnEqual OverhangIrregular Hip Rafter function With Equal OverhangHexagon Rafter Angles & LengthsOctagon Rafter Angles & LengthsDodecagon Rafter Angles & LengthsPolygon Rafter Angles & LengthsOctagon Roof Framing 4 Butt Hip Rafter MethodOctagon Roof Framing 4 Butt Hip Rafter Method with Purlin Structural RingOctagon Roof Framing With Hip Rafters MiteredOctagon Roof Framing with Gazebo CupolaBay Window Roof RaftersCalifornia Bay Window Hip RaftersFrieze Block Miter AnglesPurlin Rafter AnglesSquare Tail Fascia AnglesTimber Framing AnglesHawkindale AnglesStandard Rake WallsHip Rake Walls Plan A Rotated into Roof Surface PlaneHip Rake Walls Plan B Rotated into Roof Surface PlaneHip Rake Walls Plan C Rotated into Roof Surface PlaneCarpentry Certification in roof framing Trigonometry and Geometry.Tetrahedron Angles Calculator and Tetrahedron Framing Square UsageFrench Compagnon Roof Framing Kernel Angles and Framing Square Usage to geometrically draw out a bastard hip using a framing square.Dihedral Angle CalculatorCrown Molding Miter and Bevel Angles Calculator for Compound Miter Saw Settings and Rake Crown Molding Miter and Bevel Angles,Polygon Crown Molding Miter and Bevel Angles, Radius Bullnose Crown Molding Miter and Bevel Angles and width, Horizontal to Rake Crown Molding Miter and Bevel Angles .Hopper AnglesUnequal Pitched Gable Rafters with Unequal Plate Heights  Jack Rafter Plumb Layout Marks on Hip RafterAlhambra Granada Ad Quadratum Ground Plan Roof RaftersHip/ Valley Rafter Roof Angles for equal and unequal roof pitches for any plan angleHip Rafter Backing AnglesHip Rafter Plumb Backing AngleHip Rafter Side Cut Angles Peak of Hip RafterHip Rafter Side Cut Angles Foot of Hip RafterJack Rafter Side Cut AnglesRoof Sheathing AnglesHip Rafter Purlin Housing AnglesHip Rafter Diamond Post Miter & Saw Blade Bevel AnglesPlywood Roof Sheathing Offset Cut LineValley Sleeper Miter & Saw Blade Bevel AnglesDormer Square Tail Miter & Saw Blade Bevel AnglesPurlin Layover cut perpendicular to roof surface planeSegmental ArchesGothic ArchesLofting -- Plotting Ellipses for Arches or Groin VaultsGroin Vault Plotting -- Lofting Equal Height OrdinatesClipped Hip Rafter Octagon Roof FramingProw Rafter Roof Framing AnglesLaw of Sines Formulas Reference SheetPyramid Hip Roof Framing for Bastard Hip RoofsCutIn Dormer Shed Roof Rafter CalculatorPitch Break Shed Roof Rafter CalculatorDormer Shed Roof Rafter Calculatordévers de pas angles for WorldSkills Carpentry CompetitionCircular StairsSpiral - Helical StairsTangent Hand RailingGambrel Roof with Crow's BeakTrapezoid With Unequal OverhangTrapezoid With Equal OverhangPlatonic SolidsArchimedean SolidsBarrel Roof DormerEyebrow Roof DormerUser input modesImperial/English/Metric/Base 10Display output modesImperial/English/Metric/Base 10Display and input modes can be completely different.The app's main screen uses a left swipe motion to display all of the different calculators.
