This 42 minute ArchiCAD training lesson explores basic creation and manipulation of simple hip and gable roof systems, those with a single plate height.
The demonstrations are done in ArchiCAD 14 (representing the methods used in ArchiCAD 10 through 14) and then repeated with variations in ArchiCAD 16 (showing the new options available starting in ArchiCAD 15 for working with multi-plane roofs). Users of ArchiCAD 15 and later will find it useful to watch the entire presentation, since there are times when you may need to split up multi-plane roofs into single plane roofs, or create them from scratch, in order to achieve certain results.
Manipulations include changing overall parameters for a roof system such as slope angle, overhang, material, and line-type style; as well as modifying the slope of individual roof planes, removing a hip roof plane to create a gable, and adding in an extra plane to a gable to create a hip. Various methods of trimming walls to the roofs are demonstrated, including the classic “Trim to Roof” (which leaves a static cut), Solid Element Operations (which retains a relationship between the elements and will update automatically), and the (new in ArchiCAD 15) Connect command to Trim Elements to Roof/Shell, which is similar to Solid Element Operations in that it updates as needed to retain the relationship between the elements.
Some subtle points are shown, including the importance of understanding and perhaps adjusting the Trimming Body setting for a Multi-plane Roof – changing it from Pivot Lines down to Contours down.
