Hip/Valley Rafter Function [Hip/V]   Enhanced Hip/Valley Rafter Function

Starting with version 2.0, BuildCalc's Hip/Valley function has been enhanced to display the most information with the least number of keystrokes.  One press of the [Hip/V] key and all Hip/Valley function results are displayed in a list.

The [Hip/V] key calculates the layout geometry for a Hip or Valley Rafter based on the Regular and Irregular roof geometry, as described by two of the following: [Pitch], [Rise], [Run] and [Diag]


If the Hip or Valley is the junction of two roofs of the same pitch (a regular hip roof) the pitch is entered using the [Pitch] key.  If the Hip or Valley is the junction of two roofs of different pitches (an irregular hip roof) then the first (regular or major) roof pitch is entered using the [Pitch] key and the second (irregular or minor) roof pitch is entered prior to pressing the [Hip/V] key.
