In this video, we're going to describe the differences between survey and coordinate geometry points, often referred to as COGO points.
00:15
On the left of the display window, we have a survey point number 578,
00:20
and on the right hand side of the display window, we have a COGO point, point number 579.
00:25
We have four bulleted differences between those points. We're going to walk through them and we're going to show the differences inside of Civil 3D.
00:33
The first difference is that survey points are displayed on both the Prospector and the Survey tabs,
00:38
whereas COGO points are only displayed on the Prospector tab.
00:42
If I go to the Survey tab of the Toolspace and I go to my Survey, Import Event, and I select Survey Points.
00:51
Down here, you can see that point 578 is displayed only.
00:56
We do not have point 579 showing up in this location.
00:60
Whereas in the Prospector tab, under Points, we have both point 578 and point 579 showing.
01:08
The second difference is that survey points have an icon next to them that looks like a survey target,
01:13
whereas COGO points have an icon next to them that looks like a circle overlaid on crosshairs,
01:17
that is displayed below in the points list showing the survey icon or the COGO point icon.
01:25
The third difference is that survey points cannot be moved or edited without accessing the survey database,
01:32
and using specialized commands for editing survey points, whereas COGO points can be moved even using basic, non-Civil 3D drafting commands.
01:39
If I select a survey point and I try and move it using grip editing, it will not move.
01:46
And if I type in a command to move it, when I slip the movement of it, it will bounce back to its original location.
01:56
Whereas a COGO point can be selected, grip edited, and moved using a Move command.
02:05
To edit a survey point, you have to go to the Survey tab, go to the Survey Points and choose to edit those points.
02:13
In here, in the Panorama window, you can select the easting, the northing, the elevation, the description or the point number and change them.
02:22
The other difference is that survey points cannot be edited in the Properties window, whereas COGO points can be edited in a Property window.
02:31
If I go and select the points and right click and choose Edit Points, inside of the Panorama window,
02:37
you'll notice that the survey point is grid and uneditable for the point number, easting, northing, point elevation, and raw description.
02:45
Whereas the COGO point can be edited for point number, easting northing, point elevation.
