Change color/highlight specific elements from MEP and ELE programmatically

sivaranjani.jayaprakash — Mon, 01 Nov 2021 16:14:55 GMT

Hi,

I am new to Revit APIs. I am figuring out ways to highlight only selected elements from pipes and lighting devices by changing their colors to bright red or so, similar to Paint functionality for Walls. I also want the highlight to remain in the render as well. How can I do that in Revit and also is there a way to achieve it programmatically using element ids (I see that this can be achieved for solid elements using Paint API, but Paint doesn't seem to work for Pipes if I am not wrong). Any leads in this regard will be helpful. Thanks.

Welcome to the Revit API!

First of all, I recommend looking carefully at the getting started material:

Also, you should always explore how to solve a task in the user interface before trying to address it programmatically. Otherwise, you might end up wasting a lot of effort going in the wrong direction.

If you want to dive straight in to programming, though you can take a look at the Revit SDK samples VisibilityControl and ViewFilters.

I would look into the SelectionFilterElement class. You could create a filter based on your current selection and apply it to the view, setting everything in the selection to a specific color using OverrideGraphicSettings like in the example from the SelectionFilterElement link.
