You may receive an ESRI Shapefile collection from a GIS user for a data source in generating a surface. This is typically a ShapeFile Type 1 (Point) or Type 2 (Polyline) which contains the XY values in the .SHP file, along with the elevations in a field of the associated .DBF file.
You may have noticed that when you try to copy named objects in Civil3D (or use the same name) that it will append a (1) to the name. What you might not have noticed is that if the string case of the named object varies, Civil3D will let you create what we consider to be a duplicated name !
There are times within every project where something (or many things) can gum up the works and slow your group’s productivity. The question is how prepared you are tor them in advance and how you react when they do happen. When you hit a snag and one or more team members end up spending hours doing repetitive tasks, do you dare bill for all that time?
When gravity and moisture begins to work on steep slopes (disturbed or natural) the results are often less than optimal and slides occur. This can present the need to install anchor bolts and plates going from the loose surface to a more stable rock strata underneath. Boreholes can help determine the location of the stable strata, but from the surface it’s not readily apparent how far (on a given slope) you will need to drill to reach the stable member.

November 4th, 2016 was a day to remember, as Autodesk had just released a 16.2 revision to Civil3D that provided what initially appeared to be some useful improvements to the Civil3D API (Application Programming Interface). A couple years before (11-29-2014) we had requested several improvements to the API to allow the creation and editing of FeatureLines on a level similar to polylines.
If you receive a drawing from a Civil3D user, there is a possibility it contains CogoPoints that appear locked. You can’t move them, you can’t rotate them, etc. Since you don’t have the Survey Database you can’t unlock them like the original creator did. If this happens to you, read on.
Like a lot of things in Civil3D, it is possible but not easy to do. This post is an attempt to provide a step-by-step procedure on how to add additional properties to AeccCogoPoints.
The process of importing contours from shapefiles is actually a two step process, since the results from Autodesk’s MAPIMPORT command does not elevate the resulting polylines. This is a step-by-step procedure on how to take a shapefile of contours to elevated polylines in AutoCAD (Map/Civil3D).
We’ve often said “we don’t mind hard work, it’s unnecessary work that bothers us“. Such is the case in obtaining lidar data for surface generation. From our previous experience the process involved:
- Use a browser to go to a certain government website.
- Zoom and pan around till we found the area of interest.
- Click to select our area and place our order.
- Wait for an email to arrive telling us our data is ready.
- Download to find it’s a massive file.
Deleting parcels (by name) in Civil3D can sometimes be difficult. Right clicking the parcel name doesn’t work, erase on the parcel label does nothing. Here is a step-by-step procedure to quickly delete multiple parcels by name, without picking a single segment.
