Don’t do this… unless you want to break your span

Would she just SHUT UP about the span labels?  Jeez. 

So James gave me a template to write, and being the big nerd that I am, instead of taking coffee breaks, I take spanning breaks.

I had been having a problem where for seemingly random reason, I would suddenly have natural vertices appear on my parcel segments where I had been so careful not to create any.

Well during my last spanning break, I figured out how I was breaking my span.

I begin with a series of parcel segments that I had created from one continuous polyline using Parcels>Create from Objects

Then I realize that a little segment there to the left is just a bit wrong.  So I want to delete that segment using the Parcels>Edit Parcel Segment>Delete SubEntity tool.

Blammo.  Vertex city.  Nothing is going to span this.

This also happened to me on a cul de sac.  The entire lead road and cul de sac had been one continuous polyline that I turned into a parcel segment.  The two line segments leading into the arcs were going the wrong direction, so I erased them (as above) and redrew them in the right direction, and in the process, I blew my spanning curves around the cul de sac.


1. Check the living heck out of your geometry before you turn them into parcels.  Check that natural vertices are only in places you need them. It is one of those “sharpen the saw” things…. the more time you spend getting your data ready, the easier it will be to label and the less time you spend in revision purgatory.

 Try to draw things in the right direction, use the “no plot direction arrow” trick from last night’s post to note a segment’s direction and fix it then and there. 

Another thing I have done a few times is actually to use the general line labels to label everything with a “check” label before I turn them into parcels.

2. I used to say – define your ROW and continuous long lines from closed polylines, but after this, I am not so sure.  I like the feeling of “closure” that a long polyline gives me (I know there are no “leaky buckets”), but the above is more likely to happen with the long continous segements.  Maybe make a pline, then explode then define? 

3. Avoid using the “Delete Subentity” tool once you have labeled your lines.

4. Your suggestions?
