Sketchup Roof Rafters

Continuing the shed project in sketchup i show how to calculate the length of rafters in the field and also draw them.

Sketchup roof rafters.

Drawing them first will help understan. As for instance there is a 6 12 pitch on a roof that goes up 6 inches per 12 inches of horizontal run. The roof rafters provide integral structural support to the roof. Seat cut in birdsmouth is 4 3 1 2 top plate 1 2 sheathing.

Eaves will overhang 12 with addition of 2x fascia. A dutch gable rafter roof with hip and ridge. Rafter components of 2x4 through 2x12 with pitches from 4 12 through 12 12. This script has everything going for it.

To use 1001 bit tools we re going to start by generating the footprint of our roof as a face. Leave a comment below and let me know what you thought. A roof s pitch refers to its vertical elevation across its horizontal span. Explore the world s largest free 3d model library but first we need some credentials to optimize your content experience.

Then we ll use the automatically create hip roof function to generate the roof faces then finally we ll use the generate rafter function to finalize our roof. If you re framing a gable roof on a new house or building a shed or even a doghouse with a gable roof you ll need to cut a number of roof rafters. Before you cut your boards you ll need to measure the width of your building and calculate the exact length of each rafter.

The angle or pitch of a roof is measured by the number of inches for each 12 inches horizontal expansion.
