1805 – Complex Roofs

I often find that the standard Vectorworks roof will not make the roof that I want. If you work on renovation projects, you will find that the standard Vectorworks roof will not be able to draw the final roof that you want, and sometimes you will find that the standard roof will not draw the existing roof because people have added and extended the building over the years.

How can we make Vectorworks do what we want, or is there a way that we can help the standard roof do what we want?

The roof that I will be using can be dealt with in two ways. You can use the standard Vectorworks roof to make most of the roof, or you can use roof faces to make the complete roof. However, there are times where it takes you so long to sort out the standard Vectorworks roof that you may as well have started directly with the Roof Face command. So, it’s important to learn fast ways to make roof faces.

Using the standard Vectorworks roof can be very quick to set up. In this example, it is quicker to make a standard roof than to use roof faces. This is because it takes longer to set up guidelines for the roof faces.

## Roof Setting Out

One of the main things to look at is how the roof is placed in 3D (the roof bearing height). The Vectorworks dialog box for creating a roof includes the bearing height of the roof, also known as the pitch line.

The bearing height is measured from the Layer Elevation, which means that the Layer Elevation has an important effect on the bearing height. The Layer Elevation is added to the bearing height to give the roof elevation.
Some users set up the layers so that the roof layer sits on top of the wall layer. Since the bearing height of the roof is measured from the Layer Elevation, the roof bearing height should be 0. This is great if you don’t have multiple roof levels. Not so great if you do.

The way that I set up the layers is to have the roof layer at the same elevation as the floor supporting the roof. That way I can easily set the bearing height of multiple roofs to the correct elevation (measured from the floor slab). This makes it so much easier to remember the bearing height of each roof. Instead of trying to mentally calculate the bearing height, I can use the roof editing dialog box.

When you have a two-story house, it can be confusing. I use the same concept as above. The roof layer for each story has the same elevation as the layer supporting the roof (the wall layer).  In this example, Roof-1 has the same elevation as Floor-1. Roof-2 has the same elevation as Floor-2. This makes it easy for me to keep track of the bearing heights of the roofs.

## Standard Vectorworks Roof – Create from Walls

Select all the walls.  Make sure that you have only walls selected. The command that we will be using will not work with other objects.

• If you are using Vectorworks  Architect, go to the Menu bar.
• Choose AEC > Create Roof…
• If you are using Vectorworks  Landmark, go to the Menu bar.
• Choose Landmark > Architectural > Create Roof…
• Fill out the dialog box with the required settings.

• Click on the OK button.

This command will create a hip roof and place it on the layer specified in the Layer field of the dialog box.

## Standard Vectorworks Roof – Create from Polygon

As well as using walls to create the roof, you can also use rectangles and polygons.  In this case, I have a polygon that is the same shape as the walls used in the previous example. Creating a roof from a polygon can be useful when you want to change or create part of a roof that does not line up exactly with all of the walls.

• Select the shape. Ensure that you only have the required shape selected.
• If you are using Vectorworks  Architect, go to the Menu bar.
• Choose AEC > Create Roof…
• If you are using Vectorworks  Landmark, go to the Menu bar.
• Choose Landmark > Architectural > Create Roof…
• Fill out the dialog box with the required settings.
• Click on the OK button.
