Accurate orthogonal/elevation shadow studies

How can I create an elevation looking away from proposed works towards a neighbor, accurately showing the proposed works shadow on the neighbor?

To create an elevation that accurately shows the proposed works' shadow on a neighboring property in Revit, you can follow these steps:

  • Set Up the Project Environment:
    Ensure your project location, orientation, and true north are correctly set in Revit. This is crucial for accurate shadow studies.
    I will highly suggest using Autodesk Forma to generate geolocation and contextual buildings.
  • Create the Proposed Model:
    Model the proposed works accurately in Revit. Ensure all elements that will cast shadows are included.
  • Model the Neighboring Context:
    Model the neighboring buildings or contexts that will receive the shadows. This doesn't need to be highly detailed but should accurately represent the massing and location of the adjacent structures.
    The easiest way to generate context will be to use Autodesk Forma to provide contextual information. If you don't have access to Form,a then you can get context information up to 1mi x 1mi in CADPmapper.com
    Or you can model basic massing blocks if the scope is small.
  • Create an Elevation View
  • Adjust the View Range
  • Enable Shadows
    In the elevation view, go to the "View Control Bar" at the bottom of the screen and click "Shadows On" to enable shadows.
    You can adjust the shadow settings by clicking "Graphic Display Options" and "Lighting" to set the sun position for accurate shadow casting.
  • Set the Sun Path:
    Go to the "Manage" tab and select "Sun Settings."
    Choose the appropriate date and time for your shadow study. You can use the "Still" option for a specific time or "Single Day" for various times.
    Fine-Tune the Shadows:
    Adjust the sun settings to ensure the shadows are accurately cast on the neighboring property.
    You may need to adjust the time of day or date to see the shadows as required.
  • Annotate and Document:
    Use annotation tools to label and document the elevation view as needed.
    You can add dimensions, notes, and other annotations to clarify the shadow impact.
  • Export or Print:
    Once satisfied with the elevation and shadow representation, you can export the view as an image or include it in your construction documents.

I've followed similar steps within Revit. I am seeking a solution innate within Revit, without add-on.

It seems a reasonable expectation for Revit to cast accurate shadows both in perspective and orthogonal.

In this instance, it seems like Revit's limitation is that doesn't not cast shadows from objects behind the camera.
