Changing Slope of MEP part before placing it

[Pinchus_Main]

I want to be able to toggle between slope UP and DOWN using a hotkey when placing new MEP parts. See attached screenshot

I have achieved a similar functionality of changing pipe to hot water, cold water, storm, vent etc. using hotkeys using pyRevit. So, I have a basic understanding of how to work with different elements in Python/pyRevit. But based on my research so far, I think that I need to have the element that I want to manipulate already added to the document if not selected. Now I am dealing with parts that I am yet to add to the document. Is there a way to programmatically achieve this? Any help in this direction is highly appreciated.

I asked the devteam for you.

The devteam reply: Unfortunately, the setSlope method was not exposed to the public API. Possibly, there was some concern that it could have been also used for fittings since fabrication parts can be all types of parts not just curves like design components. We will have to look into adding something for fabrication straights.

Oh.. Is there a possible workaround for it?

I am not aware of any alternative Revit API support for this.

Of course, if you hack and dig deep enough, you can achieve anything you want using the Windows .NET API and native libraries, cf.:
