This is a sample of the LadderMaster dialog that will drive the whole program.
There will be a default for all the info needed to draw the ladder (except height "T/O landing (B)", and "Head clearance (C)").

Six easy steps to a complete shop drawing:

1) Enter the landing height "(B)", then the head clearance "(C)".
(Total "A" will be calculated using "B" & "C", and will be grayed-out)
