The first will be 2D lines (contours) that will need some work later, but I want to see what we have to start with. Let’s review some ways to produce data components. With the unnecessary layers turned off, we are now ready to produce a file to send to the field. This process is critical not only for data, but the field controllers will either not display or even crash with other than polyline exports. Sometimes when you are elevating along curb, the line will break because it is next to a different type. The conversion of different linetypes into polylines will make things easier.Looks like it came from a couple xref plan lines that were stacked on each other when they exported everything to one file. The duplicate lines were extreme in this file.I will add line points back later, but at this stage I want a straight line to have no interruptions until I add them. I got a lot of help here with lines and verticies.Listed below are notes on Drawing Cleanup results: When completed I can get the layers stripped and create a layer state for building data. The following settings will work fine for this drawing. There are a lot of options for cleaning including bringing in CAD elements that may otherwise get lost in other platforms.

Starting with Drawing Cleanup is where we’ll begin. You will need to get some things out of the way to create data. As I go through the steps, you will see some different approaches to the process that may help users with various situations. Before sending things out to the field, we need to make 2D and 3D lines as well as points. Let’s get to the meat of the program and see how data is produced.
