Generating a Profile for a 147km Project

[Butterstone]

Dear All,

Excited to join this Forum.

 

I would appreciate guidance on how to achieve the below for a 147km Topographical Survey Project.

 

I want to generate a Profile in civil 3d 2018. I have a center line with elevations along the line at 24-25m intervals. I also have the CSV file with the Eastings and Northings coordinates of each of the points

 

The process should be automatic..

 

I have attached an image of what the profile should look like.

 

Your help is appreciated.

Thank You.

I have moved your thread to the Civil 3D & LDD Forum, please post your Civil 3D questions in this forum.

A couple of ways to achieve this as it sounds like you only have the single Profile points, you can make a pline of the points ie XYZ, copy that pline left and right, you can use the points to make a TIN, using the central pline as an Alignment you can walk along the pline and make your Long section using the normal CIV3D road plot commands.

I've done this before, when I had centerline elevations but not much else. Import the points. Connect them with a polyline (the CNCPT command may help). This polyline will be helpful in the next step, so don't erase it when you create your alignment.

 

Offset the centerline (that polyline we talked about) about two feet. Connect one end, Join it to the sides, and Close the polyline so you have a border. Create a surface using your points and that border. Define a profile with the new surface and the alignment.

 

When you have styles for the profile view and the labels the way you want them, add them to a template so you don't have to go through that process again.

 

Edit: Sorry, the CNCPT command is a third-party product, i.e. it costs money. That was the first result from Goggle. You can use the 'PN command instead (don't forget the quote) if your points are numbered to match the progress of the path.
