Putting theory to work.

    The worksheet Log Angle Generator returns solutions for angles required for a complex roof system. This is an abridged version of the worksheet Timber Framing Angles; the link labelled Lag is a short Javascript version. More information on uses of this worksheet are listed under Alternate LAG Program Applications.

    LAG (Javascript) integrates Lag with a different value return format, a basic Trig Function Calculator, and a link to an Alphabetical Formula List window.

    Working Point Co-ordinates is a worksheet that solves the endpoints of lines (vectors) in a Standard kernel. Open the Vector Products Calculator as a window to work in conjunction with the spreadsheet to solve angles.

    Cognate Kernels generates formulas for both Standard and Rectangular (or Interlocking) kernels. Not all known formula variations have been listed in this worksheet.

    To convert online calculator returns to values for a framing square, open Lag and Over 12 as windows, copy and paste the angle in the Degrees field, and select the desired Fraction.

    The Quattro Pro 8 version of the Hip and Valley framing and joinery angle worksheet LAG.wb3 is not supported by this website. Available on request.
