Project Object in CIVIL 3D

Hi all,

I have started to use CIVIL3D 2007 instead of LAND-DESKTOP 3.

(I'm a little old-fashioned..)

My question is:

When I used LDD I created a surface, then drew a polyline and by right-clicking chose "Project object".

This option produced many new points along my polyline which I used for my design.

When I tried this with CIVIL 3D I couldn't find this option.

I can create a quick profile, however, this is not good for me

because I need the data as a collection of points with coordinates & elevation, and not as an image.

Could someone please help me with this?

Is there any way to produce a projection on a surface (from a polyline)?

Or getting some information from the quick profile in the way I need?

Thanks a lot,

S_G_I

Use a "Feature Line" for this. There is a command to make a feature line from an object (polyline) and when you do it there is an option to "Assign Elevation" that will add the points on the line where it crosses the surface triangles.

I agree with Peter that you should make a feature line from the object but, if you aren't familiar with the interactive nature of the Site in Civil 3D, I would recommend not using feature lines just yet.

 

The command to assign elevations from a surface to a polyline is found on the Modify tab of the ribbon on the Edit Elevations panel (at least I'm pretty sure it is as I don't have Civil 3D on this computer). I believe it's called, "Elevations from Surface".

 

Note: If you are using 2012, make sure you do NOT select the polyline prior to running the command as that will result in a fatal error. Instead, run the command and then select the polyline.

Two things on the last post:

 

1. You can add the elevations as the feature line is created (option in the create dialog)

2. The pick first issue should have been fixed with SP1 (it works on my machine).

He's using 2007.  I can't remember if that PICKFIRST thing was a problem back then.  To the OP, you'd be doing yourself a huge favour if you used 2012 instead of 2007.  I know this may not be possible but it is what it is.

Nope. Still get a fatal error every single time even with the service pack installed. Create a 2d polyline in a drawing that contains a surface (in Civil 3D 2012 with SP1 installed). Select the polyline. Run the command FEATUREELEVSFROMSURF, make sure "Insert intermediate grade break points" is toggled on, select the polyline again (yes, you have to select it because if you don't the command does nothing). Fatal error. Every single time. Every computer I've tested this on has had the same result.

How do I project a 3Dpolyline (already assigned with elevations) into an existing suface. I need to project with 2:1 slope for example.
