This question already has an answer here:

I am working on a project which runs on ArcGIS platform using VB.NET. It is to model a sub-surface fault plane (currently a plane rectangular model with some dip) and then to find required distances from various points on surface of the earth. These distances are not necessarily nearest distances.

One idea I got and decided to use is TIN network.

I want to know if this is productive given that the number of points I know on surface would be only 5.

Is there any better option to model this?

And one more point I want to remind is that we can not model perfectly vertical faults using that.

You could programatically construct a 3D polygon by first creating vertices then 3D segments from vertices, then a polygon. (Never tried to create a 3D polygon but I was able to create an add-in for importing borehole logs and creting 3D polylines split up by assays so it may be possible to take it to the next step)

Another way of creating a 3D polygon is by deriving existing heights from a surface such as TIN or raster. You may run into the same 2.5 rendering limitations for perfectly vertical faults. Look into geological software such as Geosoft Target which may be better suited for this type of work.
