Going back into the label style composer menu the first steps

Now expand Profile then styles, and finally curve. (see figure below)

Next, under the Text tab, click on the small box with three dots in it to bring up the Text Composer Editor. (Now you are able to click into the black box and edit its contents)

Now you will add PVI Station and Elevation, K value and Change in Grade values.  Start by clicking in the black box and hitting enter at the beginning or end of the length information already there.  In the black box, type: “PVI Station = “ and in the dropdown menu under properties on the left, select PVI Station and click the blue right arrow to insert it.  Repeat this for PVI elevation, K value and Grade Change (A).  Once all this information has been added (see figure below), select OK to return to the Label Style Composer”

Now take a look at your design profile and see if the labels appeared. If not, you may need to regenerate the model space by simply typing “rea” and hitting enter. It should look something like the following figure.
