Use the roof directives to automatically generate hip, gable, shed, gambrel, gull wing, half hip, or dutch gable conditions. Create a story and a half structure and place automatic dormers. Manually draw in custom roof planes and join them together, allowing the program to do the math for you.
Roofs can be one of the more complex components of a house – designing them should not be. We’ll review how Chief Architect’s roof tools can create any style of roof. In this live session, we will take questions about the process from the audience. Presented by Scott Harris, CKBD.
Learn how to create roofs in Chief Architect using the automatic build roof tool and how to use the manual roof tools to create and edit roof planes, change the wall properties for gable and hip roofs, learn about gambrel, shed and other roof styles.
Create a gable roof by choosing the Gable Wall setting within the Wall Specification and then building the roof.
Use the High Shed Gable Wall setting in addition to Full Gable Walls to create a stand alone shed roof or just the Full Gable Wall setting to create a lean-to style shed roof.
Use the Upper pitch setting in the Wall Specification to set upper and lower pitch options to create a gambrel style roof.
Use the Upper pitch setting in the Wall Specification with the pitches opposite that of a gambrel roof to create a gull wing roof.
Using the Upper Pitch setting on a gable wall allows you to create a half hip or clipped gable style.
Use the Dutch Gable Roof setting in the wall specification to create this kind of roof automatically.
Generate a roof on the top of the second floor as well as over the single level garage.
Use the Ignore Top Floor setting in the Build Roof dialog to have the roof sit down on the first story walls.
The Auto Dormer tool has different requirements than the Auto Floating Dormer tool.
Using both automatic roof generation and the manual roof drawing and editing techniques, you can quickly design highly customized roof systems.
Complex roof styles, including curved roof planes, can be created manually.
Two roof or ceiling planes can be joined at adjacent edges in both 2D and 3D using the Join Roof Planes edit button.
Check the Architectural Preference to Automatically Place Roof Intersection Points in order to have the program generate temporary CAD points that correspond to roof plane intersection points.
There are several methods for creating dormers in Chief Architect. The dormer tools make it easy to create dormers.
If you want to build a roof that diverges from the footprint of your building as well as the roof directives in the exterior walls, you can use Roof Baseline Polylines.
Frieze moldings, also known as frieze boards, are mounted below the eaves of roof planes and can be generated automatically using the Build Roof dialog.
Use the automatic roof tools to create an intersecting gable roof over an L-shaped structure.
Check Extend Slope Downward to extend the roof plane downward over a bumpout, instead of creating additional roof planes.
Any alcove with both a depth and width less than the Minimum Alcove value is treated as though the exterior wall continues straight across.
Use the manual roof tools to create an intersecting gable roof over an L-shaped structure.
The pitch direction and initial height of any roof plane, manual or automatic, is determined by its Baseline.
You can do significant modifications to dormers you create with the one click dormer tools by exploding them and editing all of the individual components of the dormer.
One way to produce a barrel roof is using a single roof plane that starts out flat (zero pitch) and covers the entire building.
Curve roof planes to create a domed roof over a round structure.
Compound curves can be created using two or more curved roof planes or a combination of straight and curved roof planes.
Before drawing roof planes, you should set your roof defaults so that the 3D attributes of your roof planes are correct.
When the roof plan is correct, roof planes can be locked to prevent accidental changes using the option in Display Settings for the Roof Planes layer.
Adjust settings for the soffits and gutter on the Options tab of the Build Roof dialog.
The Gable/Roof Line tool can be used to automatically generate a gable above the bearing wall of a hip roof plane. It is best used only in situations where roof directives in walls are not possible.
Specify the structure of the automatic Roof over the selected window unit in the Specification dialog.
Specify the value for Segment Angle at Curved Wall in the Build Roof dialog. A smaller angle produces more roof planes.
Use the automatic roof generation tools to create a story and a half structure with dormers where the roof bears on the second floor walls.
Use the automatic roof generation tools to create a story and a half structure where the roof bears on the first floor walls.
The program treats different Roof Groups as separate buildings for the purpose of automatic roof generation, preventing their roofs from influencing one another.
Modify roof planes using the settings in their Specification dialog in combination with the edit tools to match roof ridge elevations.
Group select roof planes and use the Transform/Replicate edit tool to adjust their height along the Z axis.
A Dutch hip roof, sometimes called a Dutch gable roof, is a combination of hip and gable roof styles in which a gable is located at the end of the ridge, at the top of a hip roof plane.
Methods for opening the roof in a variety of situations to prep for drawing a manual dormer.
In many circumstances you may want to create your own dormers manually. Here are tips on how to complete them.
You can create a decorative dormer manually as well as by using the Auto Floating Dormer tools.
Any roof plane can be turned into a curved roof plane in the Roof Plane Specification dialog.
Manually adjust roof planes to have a negative pitch to create a parapet wall structure with a center drain.
Edit the size and shape of skylights, and skylight shafts.
When the automatic dormer tools wont create the dormer you need, you can create one manually
A third gable roof is joined to a main roof in an overbuild remodeling situation. Use of rafters, trusses, and a truss base polyline are demonstrated
A technique for flaring the bottom of a roof with a curve is demonstrated.
Several new framing features have been added including rafter tails, sub fascia and sheathing.
