I would like to put ridge caps on the roof in my plan. How do I do this?


You can easily create ridge caps by manually creating and editing roof planes.

X5 and newer products have a different process for Ridge Caps in which you can automatically generate Ridge Caps on roofs, turn ridge caps on/off on a per roof basis and assign custom ridge cap profiles. 

To create ridge caps

  1. First Open  the plan file in which you would like to create ridge caps.

    • In this example, an L-shaped structure with a reverse gable roof is used.

  2. Select Build> Roof> Build Roof from the menu. On the Build tab, uncheck Auto Rebuild Roofs and click OK.

    Note: If you check this option, the program automatically rebuilds the roof if you make a change that affects the generation of roofs, such as changes to exterior walls or ceiling heights. Since we are using Roof Planes for our Ridge Caps, we want to make sure that this option is not selected. 

  3. Click the Select Objects toolbar button, then click on one of the roof planes over which you want to create a ridge cap. 

  4. With the roof plane selected, click the Copy and Paste in Place edit button to create an exact copy of the selected roof plane at the same location as the original.

    This copy remains selected so you can perform additional operations.

  5. With the copy of the roof plane still selected, click the Transform/Replicate Object edit button. In the Transform/Replicate Object dialog: 

    • Check the box next to Move;

    • Leave the radio button set to Relative To Itself;

    • In the Z Delta field, specify how far you want this roof plane (which will become a ridge cap) raised - in this example, 1" is used;

    • Click OK to apply this change. When the Transform/Replicate Object dialog is closed, the roof plane will still be selected.

  6. With the copied roof plane still selected, click and drag the edit handle located along the fascia edge of the roof plane and resize it until it is the desired width of one half of a ridge cap.

    • You can also resize the roof plane using dimensions.

    • In this example, the roof plane is resized to 12" in width.

  7. With the ridge cap roof plane in position and still selected, click the Open Object edit button. On the Options tab of the Roof Plane Specification dialog, uncheck Sheathing, Soffits, Use Room Ceiling Finish, and Gutter.

  8. On the Framing tab of the Roof Plane Specification dialog:

    • Reduce the Depth value for Rafters. In this example, 1" is used.

    • Clear the checkboxes beside Lookout, Eave Sub Fascia, Gable Fascia, and Eave Fascia to prevent these components from generating.

    • Reduce all of the other Depth values to 0.  When you click in the next field or press the Tab key, the values will update to the minimum allowed value of 1/16" (1 mm).

  9. On the Materials tab, select the "Roof Surface" component and make a note of the material assigned to it. 

    • In this example, the roofing material is "Slate Corrugated Metal.

    • Assign this same material to the "Fascia", "Sheathing", and "Soffit/Eave" components.  This will improve the appearance of the ridge caps in 3D views.

    • When you are finished, click OK to close the dialog and apply your changes.

  10. Repeat this same procedure on the remaining roof planes to create the rest of the ridge caps. 

  11. Take a 3D Camera view to see the results.

Depending on the type of roofing material in use, it may or may not be appropriate for use on  your ridge caps.  In this example, a blue corrugated metal roofing material is used, and the texture does not work well on the ridge caps.  A custom ridge cap material can easily be created.


To create a custom ridge cap material

  1. Click the Select Objects button, then click on one of the ridge caps to select it.

  2. Click the Open Object edit button and on the Materials tab of the Roof Plane Specification dialog:

    • Click on "Roof Surface" and make a note of the name of the material assigned to this component. In this example, the name is "Slate Corrugated Metal".

    • Click the Plan Material button.

  3. In the Plan Materials dialog:

    • Locate the "Roof Surface" material noted in step #2, above, and click on the name to select it.

    • Click the Copy button.

  4. On the Texture tab of the Define Material dialog:

    • Delete the entire pathname in the Texture File field;

    • When no texture is specified, the material will use the Material Color specified on the General tab of the Define Material dialog;

    • Type a more descriptive Material Name for the new material. In this example, "Slate Corrugated Metal Ridge Caps" is used;

    • Click OK to close the Define Material, Plan Materials, and Roof Plane Specification dialogs.

  5. Use the Material Painter   and Material Eyedropper   tools to apply your new ridge cap material to the other ridge caps in the model.
