Create a Civil 3D Surface using Plex Earth's terrain data
This tutorial presents how to create a Civil 3D Surface using Plex Earth's terrain data. Converting terrains to Civil 3D surfaces is crucial for its users, for accessing the advanced surface functionality Civil 3D offers.
Step 1: Import a Plex-Earth Surface
To see how to do so, just follow the steps of this tutorial.
Step 2: Create a Polyface Mesh from your Plex-Earth's Surface
In order to proceed, we need to extract from the Plex-Earth surface a form of the elevation data that can be used from Civil 3D. There are plenty of workarounds, here, but the easiest thing to do is to extract a Polyface Mesh.
To do so, we select our imported terrain on the "Terrain Manager", click on "Generate Drawing Objects" and select the option, "Polyface Mesh".
Note: You can select the option to directly import Polyface Meshes every time you import a terrain through Plex Earth, by using the "PXV_OPTIONS_TERRAIN" command
Step 3: Create a Civil 3D Surface
To create a Civil 3D Surface, go to the "Home" Tab of Civil 3D and select the option "Create Surface". Click "OK" to the dialog box appearing to proceed with your surface.
Step 4: Add the Polyface Mesh as a drawing object to your Civil 3D Surface
Now, open the Civil 3D Prospector (you can do this by typing "PROSPECTOR" on the command line), find the surface you created, expand its subfiles, and locate the Drawing Objects Option. Right-click it, and select Add.
On the window that pops up, select as an object type Polyface, click "OK", and select the Polyface Mesh you have created with Plex Earth.
All set! You have now successfully created a Civil 3D Surface.
Note: You can delete the Polyface Mesh, if you no longer need it and work only with the Civil 3D Surface.
With Plex-Earth 5D you get quick access to georeferenced high-quality elevation data to create terrain models. Using these terrain models in the Civil 3D environment, you can be benefitted from all its tools for advanced surface analysis.
Actually, there are many more features waiting to be explored. Just try the fully-functional trial of Plex-Earth 5D and get to know its amazing capabilities.
