2.4.3 - Create the Roof

You will design the roof using as a guide the roof outline (kmghk), of the roof-attic walls plan Fig. The final form of the roof, will be as shown in Fig. Take care the x,y coordinates of point (h) to be similar with those you used for the previous plans.

You will use the plan with the walls of roof - attic, you created in the previous lesson 2.4.2, as shown in Fig. 

You can, if you wish, to download the drawing h21190_roofAttic_walls by clicking here: dwg for Fig. On the website you will be directed, locate the file on category Custom Drawings/ Roof - Attic, click on this file name to download it, then unzip and save it in the folder: C:\\ACA\My_projects\house21_190\downloads\roofAttic, under the name roofAttic_walls.dwg.

 The roof design will be hipped, will follow the outline of the roof, will have a slope of 23 degrees and will project out of perimeter walls at 0.40 (m). Once you have designed the roofAttic outline or you have downloaded it and opened on your screen, you will start designing the roof of the house, according to the layout and the dimensions shown in Fig. The final form of the foor - attic in this phase of designing (without the dormer) will be as shown in Fig. At the next phase you will add a Dormer on the roof.

  • Set the Plate height, which is the height at which placed the base of the roof (Fig., to 0.60 which is also the height of the exterior walls.
  • Set the slope of the roof to 25 (in degrees).

To have a 3D isometric view of your project, on the View Cube tool, at the upper right corner of your screen (Fig., click on the corner WS of the Cube.

You can apply a Conceptual view in your drawing to have a more artistic view. To do this:

  • To set the Visual Style of the drawing, on Ribbon > click on View tab > click the arrow on Visual panel, the drop-down which will open provides a choice of visual styles defined in drawing to make current (for the moment the current visual style is the 2D Wireframe) > select Conceptual, to make this visual style current (Fig.

It's full path will be: C:/ACA/customDwg/house21-190/roofAttic/h21190_roofAttic_roof.

At the next lesson, you will start designing, the dormer  of the roof - attic.
During the drawing of the Basement Outline, you gave to point (a) coordinates (20,20) ( X=20, Y=20), and keep in mind that you will use these coordinate values for the same point in all floor plans and site plan you are going to design.
