Civil 3D – 2010 Assembly Link Tip

An associate contacted me recently regarding how to move 2 sets of train tracks through a single corridor, while keeping the ability to deviate the overall width.  The example I received had the sets of tracks identically elevated and on a single bed.  I decided to go a bit overboard, and add vertical and horizontal control.

Above you can see that I mocked up something real fast.  2 separate alignments, and 2 respective profiles.  I wanted to create a open area in the middle to add a freight depot.  I used the profiles to help me adjust the grades for the buildings.

The Assembly

Here is the first half of the solution.

I’ll list the steps below the example image, and then I’ll discuss some important items afterward.

Renumber Alignment Labels with Overlapping sequences

The following question was posted to the Civil 3D Discussion groups. 

I have a drawing with 20 road alignments and I am trying to create curve tables for them. I want the table for each road to start at 1. When I tag each curve, they keep going in numerical order…. Even if I change the numbering options to 1 before I label them….

Overlapping Tag Label Numbering

In Civil 3D 2008, the Parcel and Alignment Tag numbering was a site oriented thing. I worked it out by keeping different tables for each site, and went on my merry (and not so merry) way. Civil 3D 2009 seems to have lumped all the tags into a big pot. Overlaps can occur with labels on the same Site. I like this much better, and I have more flexible control. No more auto labeling in the 500’s, and then manually renumbering tags into the range I wanted. YES! Continue reading
