Remove Interval Error

Hello,

I have been trying to remove intervals on a line, but I keep getting the error " Remove intervals failed". Does anyone know why this could be happening? and How I can Fic this?

  • Unfortunately, theres a lot that can go wrong with intervals.  Especially if the original element (which becomes an interval after trimming or extending operations) was Persist Snapped to another element.  Its hard to diagnose without informing specifically the order of operations and settings used to create the original elements.  The new Civil Geometry tools are fraught with peril if one doesn't know all the mechanisms and factors that go into them.  In my opinion, they are too "smart" for their own good.

  • Hi Mark

    Absolutely agree, you couldn't have said it better.

    ORD civil elements for simple or short alignments, work great, but for long alignments with successive curves and complex constructions they have a lot of issues because of their "intelligence", especially when you then have to modify them.

    Best regards.

  • How do you think one should develop geometry for longer projects? 

  • I think you still need to use Horizontal Civil Lines and Arcs.  I stick to the Line Between Points tool to layout tangents.  Then use the Arc Between Elements - Simple Arc tool to fillet between tangents.  After using the Complex Geometry tool, use Simplify Geometry tool to "dumb" down the alignment.  Also, I've found that the Table Editor tool is the safest way to modify the alignment when necessary. 

    Also, I'd always make sure Persist Snaps are off when drawing geometry.  This tool creates "behind the scenes" dynamic relationships that can corrupt and alignment when they are unintentionally violated.  In general, you are working in a software that is in beta, so use the simplest configurations as possible.  I yearn for the days of my career when I was an autocad designer only.

    Good luck!
