Divide tool (on polygon) not producing associated COGO boundary lines

AlisonKelsey — Wed, 16 Nov 2022 21:23:40 GMT

Hi,

I'm using ArcGIS Pro 3.0.2 to edit parcels in an Enterprise 10.9.1 geodatabase (PostgreSQL 13.5).

When using the divide tool, I select a parcel polygon to divide using the divide tool. It divides the parcel but no associated boundary lines (COGO) are produced. Why would this be the case?

Would it be this tool?

Hello @AlisonKelsey

I have a couple questions:

1. Are you using the parcel fabric?

2. If so do you have an active record when running the divide tool?

3. If all yes to all those questions, could you post some screenshots of the divide workflow?

Thanks,

Jason Camerano

Hi Dan,

I am familiar with this tool but I'm dividing a polygon. Thank you anyway.

Yes, there is no equivalent for polygons and all the split polygon tools are for fc's.

I was hoping a polygon to polyline conversion might do it, but I don't work with cogo generally

@AlisonKelsey

The Divide tool will not divide the lines.

In this example you can see that the lines are not divided:

If you want the lines to be divided you can use the Line Intersection tool after you perform the divide.

Make sure to check the box to recalculate COGO values, then click on the 2 intersecting lines and lastly on the intersecting point. You can see the northern line has been already divided.

Thank you Amir.

So what you are saying is that the division of a parcel is a two-step process that involves individually dividing the parcel and then dividing the boundary lines.

Thank you for your time Jason. Amir has answered my question.

Hi Amir,

Another question: why, when I use the divide (polygon) tool on a file geodatabase does it create a boundary line in the associated line feature class, but does not do the same on the feature service? Figure 1 below showing steps is performed in a fgdb, whereas the same steps in the feature service show a different result (Figure 2)?

The parcel fabric supports the 'System of Record' concept. We want the parcels in our system to represent the legal recorded information.

So if your legal description specifies the dimensions on the side lines to be split in certain dimensions or proportions, you should start the workflow by splitting the lines (Create record, Copy lines To active record, split lines, add a splitting line, create seeds, build)

But if your legal description is an 'area description' that states how the area needs to be divided - then there is no reason to split the lines as it was never mentioned in the legal description.

Some parcel representations (e.g. Tax parcels for fiscal cadastre) require a dimension on every parcel edge. To meet this requirement you can easily use the Reconstruct Boundaries tool - it will add and remove boundary lines and make sure every parcel edge has a line with a dimension.
As for differences in behavior between file GDB and using feature services - there should be no difference. Please contact technical support and submit a case. They could determine if this is an actual bug or a user error.

Hi Amir,

I do not believe this is a bug, and tracking down the source of the problem was because two factors were involved. I've tested it again and got intermittent results that I now believe to be attributable to memory issues because of the intermittent nature. Additionally, after using the divide tool, the user needs to build extent and then update COGO lines. All good and thanks for your help.
