roof truss design free software download

You can choose the rise of the roof (which is its height), or the roof pitch (which is the slope created by the rafter). Start by deciding what you want your calculations to be based on. In the field above the illustration, pick either 'rafter length' or 'truss count'. To start your calculations, you need to choose from the two options mentioned above. You can use it either as a rafter length calculator, and get the dimensions of your trusses estimated or as a roof truss count calculator, which will also allow you to estimate the roof truss costs and even include the price of installation. The CAD versions of the sheets are compatible with AutoCAD 2000 and newer and have been developed to be easily plotted from the Layout tab(s) at a 1:1 scale.Our tool has two applications. The sheets are intended to augment a Javelin or Estima software layout, or one that is produced by some other means (e.g. Where a design professional is not involved, use of these cover sheets is limited to residential applications and, except for the title block, content should not be manipulated as it has been approved by Weyerhaeuser engineering for the loads and framing typical in residential applications. These cover sheets address typical framing details for residential construction and may require modification by design professional for multi-family or commercial projects. Individual Details – North America (Spanish)įire Sprinkler Details – For installation instructions, consult the Fire-Rated Assemblies and Sprinkler Systems Guide. Individual Details – North America (English) Set your drawing LTSCALE to 1/4 of your intended plot scale (e.g., LTSCALE=12 when plotting to a 1/4″=1″ or 48 scale factor).

When inserting the details directly into a PAPERSPACE drawing, use a 1:1 scale factor and then plot using a 1:1 scale.

When inserting the details into a MODELSPACE drawing, use a scale factor equal to your intended plot scale (e.g., use a 48 scale factor when plotting to a 1/4″=1″ scale).For best output results, we recommend the following: They were created at a 1:1 scale with a 3/32″ text height and use colors 30 and 134. These details are compatible with AutoCAD 2000 and newer. The details found within the following links can be downloaded to your computer and viewed using AutoCAD®.
