Change parameters of multiple cogo points at once in Civil 3D

In this video I am going to tell you how to increase or decrease the elevation of multiple points at once actually not multiple points all points in the drawing at once so you can see I have so many points inside this drawing so let us say we need to increase the elevation of all of these points by 1 meter so if you see here I have this elevation 28.58 this is 27.7 so let us say we need to increase the elevation of of all of these Point by 1 M so to do that you go to a point and click there then go to data click data then click on change in reference elevation so we need we need to increase the elevation by 1 meter so I type one and press enter so once I press enter you will see the elevation of these points uh increased by 1 M so you will see this the elevation of the points increased by 1 M so in the same manner you can decrease the elevation of all of these points at once so you have to memorize that the data will increase or decrease the elevation of the points not only one point but all points

How to Re Select the Last Selected Objects in AutoCAD & Civil 3D

Step-by-Step Guide:

Reselect Previously Selected Objects in AutoCAD / Civil 3D

If you accidentally deselect a group of objects after spending time selecting them, you can quickly restore the previous selection set.

Step 1: Select Your Objects

Select one or more objects in your drawing.
This can be any number of objects.

Step 2: Accidentally Deselect the Objects

Press Esc (Escape) or otherwise clear the selection.
The selected objects will no longer be highlighted.

Step 3: Start the SELECT Command

Click in the command line.
Type:

SELECT

Press Enter.

Step 4: Use the Previous Selection Option

When prompted to select objects, type:

Press Enter.

Step 5: Previous Selection is Restored

AutoCAD/Civil 3D will automatically reselect the most recent selection set.
The objects you had selected before pressing Esc will be highlighted again.

Quick Command Sequence

SELECT ↵
P ↵

When is This Useful?

You accidentally press Esc while selecting many objects.
You need to perform another command on the same group of objects.
You want to avoid spending time reselecting complex or large selections.

Pro Tip

The Previous (P) option recalls only the most recent selection set, so use it before creating a new selection if you want to recover your original selection.
