Automatically generate stick framing, or manually draw a truss system, setting roof directives for cantilevered, hip, attic trusses, and custom ceiling planes for scissor trusses.
In Chief Architect, roof framing is directly related to the way you build your roof and the roof's properties. Many roofs today are truss framed and designed by a third party. You may want to quickly build the roof's framing to create a 3D view; but, what if you need to show a section of a house with a specifically engineered truss? We'll discuss these and other roof framing details in this session.
Basic roof framing can be automatically generated and then modified manually.
Several new framing features have been added including rafter tails, sub fascia and sheathing.
Create custom truss symbols using roof beams or polyline solids.
The Trusses tab of the Build Framing dialog allows you to set parameters for trusses before they are drawn.
Roof trusses can only be drawn manually, and created where roof and ceiling planes already are present.
A Truss Base is a closed polyline that defines the area in which valley fill roof trusses are to be built across and above the tops of normal, full size roof trusses.
To create a cantilevered truss system, you need to use Raise off Plate when building your Roof.
To create a truss with an energy heel, a vertical member is added over the supporting wall and the bottom chord stops there rather than extending into the overhang.
Trusses drawn between roof planes and sloping ceiling planes of a different pitch than the roof are called Scissor trusses.
Adjust the framing manually in order to create an opening for a skylight well.
Lookouts and blocking are easy to remove if your truss system does not require them.
Learn how to adjust lookout on center spacing for lookouts and view truss details in this video.
Step Down hip roofs are the quickest style of hip truss framing to produce.
Sub-girders are the partial trusses that butt into the doubled truss at the end of the main run.
Modify a truss to allow rafters to cross over the top chord.
Attic trusses, a variation of roof trusses, can be drawn if a plan contains an Attic area on both sides and above an upstairs room, such as in a Cape Cod style home.
On the Trusses tab of the Build Roof dialog, you can specify the Ceiling Step, which is the maximum distance its bottom chord can step down to locate a ceiling on the floor below the top floor.
