AutoCAD has a long history, and we go back all the way. Our primary developer started using AutoCAD with version 1.0 on the original IBM PC with a 10mb hard drive and CGA graphics (now we have mp3 files larger than that). Here is a detailed history, including corresponding drawing versions, .NET framework used, etc.
In the early days of AutoCAD, users could safely use a NODe osnap to snap to a point block while zoomed out because they knew it would only return the actual intended point of the insert. Then along came an
improvement that had AutoCAD return the insertion point of the attributes. With that improvement meant you had constantly zoom in to make sure you were getting the right point.
For those that aren’t aware, the OSNAPNODELEGACY set to 1 causes the CAD engine restore the logical NODe osnap of the point object only. Now in the highly unlikely case you want to snap to attributes, you can use the INSert osnap.
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.

When we worked up our procedure for importing Lidar into Civil3D a couple months ago, we realized there were way too many steps and way too many hoops to jump through. Hoops preparing the data, through Recap to prepare a RCP/RCS, through Civil3D creating a point cloud, and finally creating the surface. Highly trained professionals have more important things to do with their time than spend it like a well trained circus animal jumping through hoops, so we did something about it.
Like many things in Civil3D, they can be done but how it’s done isn’t so obvious. In the process of adding a DEM surface to your drawing you may notice that you can’t project it to another coordinate system (that of the drawing). Here is a step-by-step procedure including assigning a coordinate system to the current drawing.
ESRI Shapefiles are not just the SHP file. While some importers can import the geometry from just that one file, a lot remains missing. That’s why it’s important to send the package, not just a single SHP file.
We’ve seen people struggling with the confusing Set Location tool in AutoCAD (2015+) that also requires you to log into 360 using an internet connection. We’ve also seen peoples disappointment when they discovered that (and panning Bing images) was pretty much all they could do with it. Then there were the users of previous versions with even less GeoLocation tools. Since we love all things mapping we decided to do something about it.
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.
We have been receiving support issues ranging from program files being invisible (as in saying it can’t find a file you know is there) to outright alerts of our code being a virus. These have of course turned out to be false positives, a failure on the part of the antivirus software. A company that’s been in business for nearly 30 years does not produce viruses.
