It appears that Divide Lines does not have a way to keep the parent line attributes. Is this correct?

DeanAnderson2

I am working with the Divide Line tool. My line feature class has several key attributes. When I divide the line (ie. 200 feet from beginning). The tool creates the two new lines correctly. The parent has the retired by record field assigned correctly making the parent line historic. So Far all is good.

Unfortunately, I have a number of attributes (such as LineType) that are not replicated in the children while others (cogo attributes and a field called source) are. Is this the expected behavior ? (Also I am using 2.8.3). The documentation is pretty clear that it should keep the attributes. I am just not sure why my linetype is not kept (it has a domain) and why I lost my cogo distance on the remainder.

Please let me know

Thanks

@DeanAnderson2, this is a bug that is present in 2.8 and earlier. It has been fixed in 2.9. If you are already on 2.9, then please let us know so that we can follow up. The second line's COGO distance is calculated, so if you are using the parcel fabric, then you should see the COGO Type field set to "Computed".

This sort of thing is governed by domain split / merge policies.

https://pro.arcgis.com/en/pro-app/2.7/help/data/geodatabases/overview/an-overview-of-attribute-domains.htm

Split policies are:

Default value—The attributes of the two resulting features take on the default value for the attribute of the given feature class or subtype.
Duplicate—The attribute of the two resulting features takes on a copy of the original object's attribute value.
Geometry ratio—The attributes of resulting features are a ratio of the original feature's value. The ratio is based on the ratio in which the original geometry is divided. If the geometry is divided equally, each new feature's attribute gets one-half of the value of the original object's attribute. Geometry ratio policies only apply to domains for numeric field types.

It sounds like you want to set yours to Duplicate for things like the LineType field.

Thanks Tim.

@DeanAnderson2- I just read from your original post that you are on 2.8.3. As mentioned in the prior response, this is fixed in 2.9.

DeanAnderson2

First - thanks so much for help on the duplicate domain issue. That fixed the problem.

On my second issue. I was concerned about the line so I created a NEW line with the traverse tool (just a simple 200 foot long straight line as illustrated above). Attribute for cogo enabled was "entered" so not sure what is going on.

Glad it works as expected for you. At least that means I understand how it is supposed to work. Now just have to figure out what is wrong.

I am not sure what a "true COGO-Enabled Line" is. I have replicated my problem using my converted taxlotline COGO data from ArcMap (non-fabric) and also from newly created lines. We have been testing and using other commands such as Traverse on this dataset for months and it has been operating correctly (as expected). I have also replicated my problem on a non-fabric COGO feature class that has had the "Enable COGO tool" run. I assume this makes a COGO line? So I think I am using COGO enabled lines. I there some setting I missed?

That does not look like normal behavior. If I try the same thing, I get <remainder line length> = <parent line length> - <division length>. In your example line, a 100.

Where is the line coming from? Is it being added as a true COGO-enabled line?

DeanAnderson2

Had not used that for domains before. That fixes the domain attribute. As to the CoGo Attributes I am not sure what is up. I just entered one line using traverse. (n44-00-00e 200 feet long) as below.

I then use the divide tool and divided the line from start of line 100 feet and the results are:

What I expect to have happen (and based on your response) would be two lines both with a length of 100. Instead my second line (while retaining the direction) has a NULL distance. Is this the correct behavior?

I am not getting something.
