Drawing a shed dormer

• Draw the main roof, e.g. a gable roof, on a document.

  

  Fig.: Main roof

• In plan view, draw the outline of the shed dormer in construction-line format.
  As the dormer automatically intersects the main roof, the outline can extend as far as the ridge.

To draw a shed dormer

1. Click Dormer (How).
   

   Activate Dormer in one of the following ways

   • Menu bar: Create Architecture General: Roofs, Planes, Sections

   • Palette: Tools Create area in the following module(s):

   General: Roofs, Planes, Sections

2. Click the roof frame in which you wish to insert a dormer.
3. Enter the outline of the dormer. Circumscribe the preliminary design you have already created.

   As soon as the polyline is closed, the program prompts you to click the edges of the roof frame to apply slopes.

4. On the Dormer Context toolbar, set the parameters as follows:

   Note: The height parameters are absolute coordinates.

   • It is important that the elevation values you enter for the Bottom Level and for the main roof are exactly the same.
   • The eaves will be higher than the eaves of the main roof:
     Enter the outline of the dormer first and use Measure (How) to get the height value of the point where the dormer and the main roof intersect in elevation view. Now you can enter the value of the desired opening height of the dormer to this value and enter the result for the Eaves.
     

     Activate Measure in one of the following ways

     • Menu bar: Tools

     • Keyboard: Ctrl+Alt+M

     • Toolbar: Standard

   • The dormer's slope will be less than the slope of the main roof.
5. Now click the outer boundary line of the dormer to apply the slope for the plane.
6. Press ESC to quit the tool.

   The result might look like this:
