A popular request is to export geometry in a Civil3D drawing to Google Earth in a KML/KMZ format. This post contains details on how to do it, with a step-by-step procedure for Civil3D. For recent versions of Civil3D, you will want to use the EXPORTKML command because it will support the most object types (including AECC objects). However it has some quirks and this procedure may help iron them out.
A frequent question is how to import Lidar data like LAS/LAZ or other point cloud formats into Civil3D. Here is a step by step procedure on the process, using Civil3D 2018 as the target. The procedure assumes you have your Lidar data files downloaded and ready in a folder.
Civil3D users notice that sometimes they can delete a surface by right clicking it’s name in the Prospector tab of the Toolspace, and sometimes they can’t (here’s one reason at least).
With many things in Civil3D, it’s not readily apparent what you need to do. Here is a step by step procedure on how to import FLT fault files. These files are ASCII files you can drag/drop into a notepad and you will see “#AdCADD DTM 12.00 User defined fault file” followed by numerous lines of coordinates.
A Civil3D forum user recently stated they have “been supplied ~500 .tiff files from a DEM which contain elevation data” and the prospect of repeating the built in Create Surface from DEM tool 500 times did not appeal to them (only to have 500 separate surfaces). So we set out to create a tool to help.
Many times users want to build 3dSolid models inside CAD engines to visualize, check volumes or 3d print. Here is some procedures to help you get started.
To transfer point groups from one drawing to another, you can use Civil3D’s built-in LandXML export and import tools.
You may have wished to fill your parcels to highlight the areas but found there isn’t a way to designate the fill transparency. The resulting fill blots out everything (even some parcel lines). Here is a workaround (using layers) to achieve it.
We have reached a fork in the road on our Civil/Survey and Mapping add-ons. For years we attempted to provide one package that ran inside plain CAD engines as well as Civil3D while using the best objects available. The problem is that it meant a weaker (than possible) Civil3D connection, prevented us from adding tools only (currently) possible in Civil3D and created confusion on what parts used Civil3D objects.
Windows users often ignore their TEMP folder. It’s a junkyard where old files (and folders) live even though the application that created them has long since been shut down. Well behaved applications keep track of the files they create there and remove them on completion of the task. However sometimes applications crash, or they just aren’t programmed to clean up after themselves.
