Class Summary
Ever wish that AutoCAD® Civil 3D® could create a dynamically linked
subgrade surface, while you build and modify your finish ground surface?
What is a dynamic differential triangulated irregular network (TIN) surface?
It is that magical TIN surface we have all wished there was an easier way
to build. It can represent many different types of surfaces. It can be used
to build a surface that represents the top of an aquifer or substrate from
borehole data. It can be used to build a topsoil stripping surface for a
business site design project. Best of all, it can be used to quickly build a
multilevel subgrade and/or sub-base surface that is dynamically linked to
your parking lot finish ground surface. It is so simple that you will leave this
class by asking yourself, “Why have I not used this feature before now?”

Definition of a Dynamic Differential TIN Surface
(DDTS)

It is a surface created from the actual depth (not elevation) of a surface
layer and is compared to the finish or existing ground surface in which
the depth is measured from.
 DDTS = Finish (or Existing) Ground Surface – Depth Surface
