Generally speaking, in AutoCAD you either select one or more entities and choose a command -or- you choose a command and then select one or more entities. When you are finished with the command, AutoCAD returns to the previous state where nothing was selected. I have noticed a different behavior in Civil 3D when working with C3D objects. When you select an object and perform certain commands (such as properties), when you are done the object remains selected.

For certain tasks in Civil 3D, I have Quick Properties (QP) enabled. I started noticing in 2013 that when QP is enabled and I select an entity, the focus is removed from the AutoCAD window. In other words, the crosshairs change to the pointer. So if I want to pick a Grip or a command on the contextual ribbon - it requires an extra pick. One pick to restore focus to the window and a second pick to activate the grip or menu item.
Many moons ago in the AutoCAD world, when you received a command prompt instead of an expected dialog box, you could check the system variables FILEDIA and CMDDIA and make sure they were set to 1. Over the years, CMDDIA has all but been phased out in AutoCAD, although FILEDIA (for FILE DIAlogs) does still apply. Here is a related post on this.
Below is a simple animation of creating a quick profile in Civil 3D. No, this is not a new feature, but there are new Civil 3D users every day - and if you have never seen or used this feature - this may help you out.
This tip came to me while working with Cogo points in Civil 3D, but it could apply to many things. A while back I had a tip about setting PICKADD to 0. Now generally, this system variable set being to 0 would annoy most people since it only allows you to select one object at a time. But if you are working with Civil 3D Cogo points, say for example dragging labels to create a dragged state, and you are doing this over and over, setting PICKADD to 0 can be a big help. Doing so means you do not have to press Escape to clear the previous selection. As soon as you pick one point, it is selected and all other selections are cleared.
Remember to turn OFF the Properties Palette when working with Cogo points. If the Properties palette is on, Civil 3D has to look up and display the properties each time a new point (or points) is selected and this slows it down tremendously. Try it both ways and see if you see a difference.
It explains how to import an ESRI SHP file directly into Civil 3D as a Surface. This will save you a lot of time compared to the old method. Even though the article mentions version 2012, it also works in version 2011.
On many civil engineering projects, horizontal control is established by the creation of an alignment, or baseline, and then identifying locations using stations and offsets from this alignment. In some cases however, we are asked to provide only the actual coordinates of the proposed feature. Civil 3D makes this easy using a Note label, configured with a style to match your needs. Below is a sample Note label configured to show the coordinates and elevation.
If you are having issues with your cursor freezing up (±45 seconds) in Civil 3D when you hover over a Cogo Point - then this should fix it. There is some indication that this is only an issue in Civil 3D 2011, but I cannot confirm that.
