TPC allows you to easily designate the points that should be used for creating your Surfaces (Contours/DTM/TIN) and editing tools that make it easy to fine-tune the surfaces. The Surfaces Learning Guide is divided into sections like Simple Surfaces, Computing Volumes and Editing Breaklines and Borders.

Introduction: Simple Surfaces (10:21) - Walk through the Learn Contours.trv sample file and create a single surface.
Slope Analysis (4:19) - Slope Analysis 1) computes the slopes 2) reports slope areas 3) shades slope areas in the drawing and 4) adds a slope key to the legend
Move Elevations To Surface (3:15) - Learn how to update elevations of survey points, moving them to an existing surface.
Export Surface To CAD: 1 (2:32) - When we export a surface to CAD, TPC sends a polyfacemesh (DWG) or polygonmesh (DGN) to you can work with the surface directly in CAD.
Export Surface To CAD: 2 (2:39) - We've made two changes to surfaces that are exported to CAD. 1) The polyfacemesh layer is turned off by default, but you can turn it back on. 2) TPC now writes contours as polylines even when contour labels are turned on.
Surfaces (55:00) - In TPC Desktop, surfaces are wickedly simple. We show you how to create a surface, then improve the surface model with breaklines and a border.
