Four Hidden Surface Commands You Must Know in Civil 3D 2016

While you may have been using Civil 3D for quite some time it’s possible that you may have missed some of these time saving commands. In particular there is a new one in Civil 3D 2016.

Well, they are not so hidden, it is easy to miss them without paying close attention! They are all situated within the Tin surface contextual tab of Civil 3D 2016 as shown above.

Create cropped surface lets you create a small cropped surface from a large surface that may have initially started out small but grew as the project size grew.

Extract Solids is a command new in Civil 3D 2016 and lets you create an AutoCAD 3D solid object from a surface object.

The picture below shows the Civil 3D surface in plan view to the left and the 3D solid extracted in 3D view to the right.
Extract Objects lets you extract surface components such as border, contours etc. from a surface as AutoCAD entities such as creating polylines from surface contours. The figure below shows the extract objects dialog box for a surface that displays all its components.
Export to DEM creates a DEM file from the Civil 3D surface object that can be used in other applications, typically GIS, that use DEMs.
