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.
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.
