Hi @CColozza
Brookport? Metropolis?
You don't necessarily need ArcGIS or ArcPro. All you need is to convert the LiDAR into shapefile (which you've already completed using Global Mapper). Using your shapefile, the entire operation can be done using Map3D/Civil3D in two parts.
Part 1 (Refer to image-1):
Open a brand new clean drawing template so you can convert the shapefile from ESRI vectors to AutoCAD polylines. Do this using MAPIMPORT command. Be sure to assign coordinate system IL83-EF beforehand. During the import process, you'll accomplish two things:
- Convert from shapefile linework to plain vanilla AutoCAD polylines.
- Capture (or harvest) the elevation values from the shapefile's database file (dbf). The captured data is known as Object Data (OD).
Name this drawing DEMO_101.dwg and save it your project folder. Once it's saved, close it and proceed to Part 2.

Part 2:
This part requires opening a brand new second drawing (or you may use your current drawing). In this second drawing, you'll perform a QUERY by connecting to Demo_101.dwg, the drawing you saved a minute ago. The connection entails Drag-and-Drop. Be sure to assign IL83-EF to this second drawing just like the previous drawing.
Drag Demo_101 from your project folder and drop it directly on a blank area of the Map Explorer Tab of the Map Task Pane. (MAPWSPACE=>enter ON on command line.) The drawing named Demo_101 is now attached to your second drawing Follow all steps to Execute Query. (Refer to images 2 thru 4).

As a final step, detach DEMO_101.dwg. by selecting it from the Explorer Tab of the Map Task Pane that you attached earlier=>right click=>Detach.
To verify proper contour elevation, use the view cube and view the contours from Top, Front and Left views. When you zoom-in close, you'll see the contours have been raised to their respective elevation. While viewing from either front or left view, select an individual contour and view its Elevation under the Geometry Section of the Properties Palette. The elevation shown under the Geometry section will be consistent with the Elevation shown at the bottom of the Properties Palette (under the section name OD:Test_Contours).
***If you run Civil3D and want to make a surface, you can use these elevated contours as your surface definition.
