Civil 3D 2012–Alignment Swapping Constraints

One of my favorite new features in Civil 3D 2012 is the ability to change Tangency Constraints on alignments. If you’ve worked with alignments for some time you’ve no doubt wanted to change a segment later on in the design. If you weren’t careful by adding in a fixed segment every so often you would soon find yourself with a lot of extra work to add in something later. For if the segment you wanted to remove was dependent on another segment then you would wouldn’t be able to remove it. Well now you can delete any of the segments within an alignment and the tangency constraints of the objects will be revised. There is even a spot to change the constraints in the segment parameter’s dialog box.
