AutoCAD Civil 3D has blurred the lines between who is a draftsperson and who is an engineer. AutoCAD tips and techniques can often be very helpful when working in Civil 3D, but many engineers may have missed out on these little drafting gems.
An example is the Fillet command. To work out the intersection point of a Kerb Return profile made by the Intersection wizard, you can draw two little lines or polylines and snap them to the ends of the road profiles you want to work out the intersection point of to reproduce the grades and elevations.
Then start the Fillet command, and on the command line select the Radius option and set the radius to 0. Selecting the ends of the short line segments produces the intersection point and this can be used to create the Vertical Point of Intersection of the profile and an appropriate curve can be added.
In this case the grades were only out by .05% at one end, which is good enough for most people!
Notes from Cadalyst tip reviewer R.K. McSwain: If you're new to Civil 3D, then keep Dean's tip in mind. Civil 3D not only includes all AutoCAD functionality, but also much of the functionality of AutoCAD Map. Explore the application, because many of these tools and commands are not necessarily accessible in the ribbon or otherwise obvious locations.
