Creating an Inclined Plane

[GlacialLab]

I'm working on re-creating past lake levels during the last Ice Age, but during this time, the earth's crust was deformed from the weight of the ice. This means that, although water levels were flat during the time of a lake's existence, shorelines now form an inclined plane, where the elevation of features changes with their x,y position.

Is there a way to create an inclined plane in Arc10 that i could fit with the DEM i'm using in order to try to correlate shoreline features?

Just make a toe and crest line with elevations and offsets that give you your desired slope and create a TIN using them as hardline inputs. I am not sure what "Fitting" them to the shoreline refers to, but I envision bringing this incline and the lakeshore into ArcScene and adjusting the base height on the incline to get it intersecting the shoreline at 2 points and then redigitizing the new shoreline at the intersection of the lake surface and the incline slope. I have tried digitizing in ArcScene before though.... put it in the birds eye view.

Hi,

Can you describe in steps how to make inclined plane in ArcGIS 3D analyst
