How to Create Layouts in Revit: A Practical Guide
When working with families in Revit, you often use the Layout command. However, sometimes the path for the layout isn’t a simple straight line—it may include complex segments that Revit struggles to process. This can cause the creation to fail. So, how can you resolve this issue? Below is a concise explanation.
In this example, we start with a Conventional Model family template. The layout path is a square, and the contour is a circle with a radius of 40, as illustrated below.
When you try to round the four corners of the path with arcs that have a corner radius of 40, the creation fails, as shown in the image.
The reason: During the formation of the model, Revit encounters self-intersections at the bends of the path, preventing successful creation.
Solution 1:
Draw the contour on the side where the path’s arcs do not intersect. This adjustment avoids self-intersection and allows the layout to be created successfully, as shown below.
Solution 2:
Reduce the contour radius to be smaller than the path’s fillet radius. For example, if the path’s rounded radius is 40, lowering the contour radius to 39 enables successful creation, as demonstrated in the image.
Summary: The Layout command in Revit is a powerful tool for creating shapes by tracing contours along paths. However, self-intersecting paths can cause failures. By adjusting the path or slightly reducing the contour size, you can overcome these issues and create your family successfully.
