Selecting Window Family Types

The next step is to go through the list of windows and curtain wall panels and select the ones that should be exported as windows. There are two ways to identify the families in the Revit model:

1. Right-click on the family name and click on Select All. That will select all the families with the same type in the Revit active view. It's usually easier to see the windows if you are in a 3D view.\

   
2. Select the family, and use the `Preview` button to preview them in the Pollination 3D viewer inside the menu.\

   

In this sample model, there are only 3 different family types, and it is quite straightforward which ones should be exported as windows. This is how the menu should look after selecting the correct families. Pay attention to the Export Status column and the Export Summary to ensure you have selected the correct families.

Understanding "Panel Calculation" options

Pollination provides 3 different options for calculating window panels:

• Single Panel

• Multi Panel

• Bounding Box

The Revit sample model includes simple windows family types, and the default Single Panel mode works without any issues, but in the real world, you will see more complex examples. Here is an example of a window that also includes 2 different shading elements and the frames as part of the window.

The Single Panel option tries to create a single panel from all the geometries. Since the shade elements are not aligned with the window, this is how the window would look when the Single Panel option is selected. Note the diagonal edge on the left side of the window.

In cases like this, the easiest way to address the issue is to use the Bounding Box option that creates a rectangle around all the geometry to generate a rectangular panel. This will, however, make the window area slightly larger than it needs to be.

Another option is to unselect the non-glass materials. That will only create a bounding box or a single panel around the glass pieces.

If you want to be very specific and create a separate panel for each piece of glass, you should use the Multi Panel option. This option is only useful when there are several pieces of glass in the window family.

Confirming your selection

Once you have reviewed the windows and doors, press OK to confirm your selection. It is time to move to the next step for creating rooms.

Frequently Asked Questions

Is it possible to only export the exterior doors and windows?

We currently don't support this option directly in Revit, but you can use the "Simplify Windows" command in the Model Editor to remove the interior windows after exporting the model.

Does Pollination include the frame thickness in the exported window?

The answer to this question is different for windows vs curtain wall panels. See this page for a detailed answer to this question.

How can I load the windows and doors from linked Revit models?

Both windows and doors menus have a dropdown for loading families from linked models. Simply select the linked model, and you will see the families loaded in the table. See this page for more information about setting up linked models.
