Hip and gable roofs created manually


ANSWER

Chief Architect allows you to create a wide variety of roofs - including hip and gable roofs - automatically. However, in some situations it's easier to create roofs by hand. In this tutorial, we will show you how to set your defaults for building a roof, how to draw roof planes manually to create a hip roof, and how to create roof planes for a gable roof. 


To create a hip roof 

  1. Select Build> Wall> Straight Exterior Wall  from the menu and draw four connecting walls to form an enclosed area. In this example, a simple rectangle is drawn.

  2. Select Build> Roof> Build Roof  from the menu to open the Build Roof dialog.

    This dialog also serves as the default dialog for roofs - settings here apply to manually drawn roof planes as well as automatic roofs.


  3. On the Roof panel of the Build Roof dialog:

    Setting roof properties such as the Pitch on the Roof panel of the Build Roof dialog

    • Set the Pitch (in 12) to the value you desire.

      In this example, a pitch of 6 in 12 is used.

    • You can also set the default Roof Overhangs here.

      In this example, the template default of 18" is used.

    • Click OK to close the dialog.


  4. Select Build> Roof> Roof Plane  from the menu.

    • Starting on the left hand side of the plan, click and drag a baseline down along the outside surface of the wall's framing layer.

    • When Object Snaps  are enabled, the program will snap the roof planes baseline to that point automatically.

    • Release the mouse button and then click inside the room to identify the location of the ridge and to create a roof plane.

      When drawing a manual roof plane, release the left mouse button to establish the stopping point or ridge


    • Repeat this process on the three remaining sides of the building.

  5. Click on the upper roof plane along its right hand side to select it. Notice that the edit handle that displays on the edge that you clicked on is bigger than the edit handles on the other 3 edges, indicating that it's the selected edge.

    • Click the Join Roof Planes  edit button.

    • Next, click the the upper side of the right roof plane to join the two edges together.

    • Repeat this process to join the adjacent edges of the remaining roof planes.

  6. Click on the ridge edge of the upper roof plane to select it.

    Selecting the ridge edge of a roof plane

    • Click the Join Roof Planes  edit button.

    • Click the ridge of the lower roof plane to join them together.

  7. Click on the ridge of the roof plane on the right side of the plan.

    Selecting another roof ridge on a different roof plane

    • Click the Join Roof Planes  edit button.

    • Click on the right edge of the upper roof plane.
       
      Select Join Roof Planes again and select an edge on an adjacent roof plane to join


  8. Repeat this process for the roof plane on the left side of the building.

To create a gable roof

  1. Select Build> Wall> Straight Exterior Wall  and draw four connecting walls to form an enclosed area. Again, a simple rectangle is used in this example.


  2. Follow the steps described in step 3, above, to create two roof planes on opposite sides of the building.

    Draw two roof planes opposite one another


  3. Click on the ridge edge of the lower roof plane to select it.

    Click on the ridge of one of the roof planes

    • Click the Join Roof Planes  edit button.

    • Click the ridge edge of the upper roof plane to join the two together.

      Click on the Join Roof Planes tool and then click on the roof ridge of the opposite roof plane


  4. Select View> Temporary Dimensions and make sure there is a check beside Temporary Dimensions. If there is not, click on this menu item to turn on the display of Temporary Dimensions.


  5. Click on the right side of the upper roof plane to select it.

    • Left-click on the temporary dimension between the roof plane edge and the wall.

    • In the text box, type a distance value of -18". The 18 represents the desired gable overhang.

    • In this example, it's important that a negative number be used. This directs the program to move the roof plane edge to the opposite side of the wall, rather than keeping it on the same side.

    • Repeat for the left edge of the upper roof plane.

  6. With Object Snaps  enabled, drag the left and right sides of the bottom roof plane so that they snap to the respective sides of the upper roof plane. As you drag each edge outward, move your cursor towards the side edge of the upper roof plane.

    Snapping the edges of a roof plane to another

    The program will locate the edge and snap the currently selected edge to it.


  7. Repeat for the opposite side.
