Editing Profiles Numerically

posted by on March 31, 2018
At times, you may want to adjust your design by telling Civil 3D the exact dimension of a portion of the profile. You can do this in one of two different ways. The first is Profile Grid View, which opens a tab in Panorama. This tab shows the geometry of the profile in table form and enables you to edit some of the values to adjust the design.

To edit a profile numerically using Profile Grid View, follow these steps:
  1. Open the drawing named Numerical Editing.dwg located in the Chapter 07 class data folder.
  2. Click the Jordan Court FGCL profile, and then click Geometry Editor on the ribbon.
  3. Click Profile Grid View to open the Profile Entities tab and display the numerical version of the profile geometry.
  4. Change the Station value for Item 3 to 2+70.00 (0+080.00) and the PVI Elevation value to 188.00 (57.00).
  5. Change the remaining items as follows:
      ItemStationPVI Elevation
      48+55.00 (0+260)196.50 (60.0)
      510+50.00 (0+320)188.50 (57.5)
      616+90.00 (0+515)164.00 (50.0)
    Tips:You do not have to type the plus signs in these entries. For example, instead of typing 8+55.00 (0+260), you can just type 855 (260), and Civil 3D will automatically fill in the required plus signs.
  6. Close Panorama. The drawing may not look very different than before because the changes you made were very subtle. Keep the drawing and the Profile Layout Tools toolbar open for the next exercise.
The second method for editing the profile design numerically is referred to as Component-Level Editing. With this approach, you open the numerical data for a piece of the profile (such as a line or vertical curve) in a separate window. You do this by clicking the Sub-entity Editor button on the Profile Layout Tools toolbar and then using the Pick Sub-entity tool to choose the part of the profile you want to edit.

Keep It Simple

As you might have guessed, the main objective of this exercise is simplification of the profile design. In most cases, the stations or elevations do not need to be located with a precision of 0.01, so why not round them off to nice, even numbers? The contractor and surveyor who are staking out the design in the field will appreciate this rounding because there will be fewer digits to keep track of and a bit less potential for error.

The PVIs of items 1, 2, and 9 were not rounded because these are specific locations and elevations that need to be met. Items 7 and 8 were already entered as round numbers when you used the Insert PVIs – Tabular command in the previous exercise.
To make numerical edits to a design profile using Component-Level Editing, complete the following steps.
(You should have Numerical Editing.dwg open from the previous exercise.)
  1. Click Profile Layout Parameters on the Profile Layout Tools toolbar to display the Profile Layout Parameters dialog box. (This dialog box is blank when it first appears.)
  2. Click Select PVI, and then click near the curve at the lowest point on the Jordan Court FGCL profile. This will populate the Profile Layout Parameters dialog box with data.
  3. Change the Profile Curve Length to 275 (80).
  4. Close the Profile Layout Parameters dialog box and the Profile Layout Tools toolbar. Again, the drawing doesn’t appear to change much because the edit you made was so subtle.
