I am trying to use the SurfaceDraper for a project but it wont do anything. The input arrow for Breaklines is red so I that seems to be the culprit. I cant see why breaklines should be mandatory? A polyline and a DEM raster should be enough to do the draping? Is there a workaround for this?
I do not believe both Point/Lines and Breaklines are required.
A common issue occurs with Coordinate Systems.
Are the Point/Lines and the DrapeFeatures in the same coordinate system?

As @erik_jan says, you don't need to supply both points/lines and breaklines.
However, I think the SurfaceDraper can't work with a raster DEM, try turning it into 3d points first with a RasterCellCoercer.

Thanks @redgeographics!
I went back and read the documentation for SurfaceDraper and the wording is a bit unclear. The input arrow is called Points/Lines, but in the description it says : "These input features may be 2D or 3D. Other than points, lines and area geometries, they may also be raster, point cloud, and aggregate geometries." Maybe someone at Safe could shine a light at this?
