Conduct a Shadow Study

Add elements and assign colours

Option 1 – Add Elements From The View

Useful for early-stage study. It works best with fewer elements that can be easily picked from the view, such as Massing, Revit groups and linked files.

Click on ‘Add Element’ and pick a mass from the Revit view (any Revit component, mass, group or linked CAD). The first element will be the top layer (usually the city context), and the last element will be the bottom layer (usually the proposed building).

Group is recommended when you want to apply multiple elements to one layer.

Option 2 – Select Worksets

Useful when your Revit project has many elements and is organized in different worksets.

Click ‘Add Workset’ and select a workset from the drop-down menu. The first selected workset will be the top layer (usually the city context), and the last element will be the bottom layer (usually the proposed building).

Area Calculation and Colour on Regions

Shadow Colour allows you to calculate the shadow area within selected regions and apply a designated colour to those shadows.

To generate a shadow area calculation, please ensure the following:

  • The view is Top and orthographic/parallel projection.
  • The site is fully contained within the view.

1. Click ‘Region’ and select a property line from the Revit view.

2. Choose a colour for the shadow of the element within the selected region.

Please keep in mind that a colour must be selected for the shadow area calculation. If you want the shadow to be displayed without colour, you can opt for full transparency.

3. Click on ‘Preview Image’ and the area calculation will be displayed alongside the preview image.

  • Please be aware that generating the preview image may take some time.
  • You may deactivate the area calculation from the settings.
