The Stair Layout tool completely specifies the layout of stair stringers. Stair stringers
can be difficult to calculate---it's not just a matter of dividing risers into the total rise.
Any given rise on a set of stairs has to be very close to all other risers in order to meet
code. The complications relate to how the stairs meet different landings, notches,
tread, upper and lower floor finishes, framing details, etc. There are a lot of variables
to keep track of in order to build a set of stairs correctly. A framing sub-contractor that
purchased MasterCarpenter years ago informed us that of the 30 people working for him he
was the only one who could correctly calculate a set of stairs when the more difficult
variables were involved. The Stair Layout tool makes laying out the most difficult
stairs simple. As part of a MasterCarpenter 2.0 project, stairs designed with Stair Layouts
can be published to your web site or printed. Included with the online documentation
is an introduction to stair framing (including open stairways) as well as examples of usage.
