Default COGO labeling expressions - getting COGO ERROR label

RobertChaney — Fri, 07 Feb 2025 21:56:10 GMT

I have a parcel fabric where the COGO field values are in meters. I'm able to modify the Default COGO label expression: var cogo_distance = $feature.Distance * 3.28084;

Which gives me the proper label in feet. However, for lines with values in the ArcLength field, the COGO ERROR label shows. When I attempt to change the variable in the default COGO expression to the following:

var cogo_arclength = $feature.ArcLength * 3.28084;

I get COGO ERROR labels on all lines.

If I take off the conversion for the Distance field, the ArcLength shows properly, but of course the Distance field shows the COGO ERROR.

Can anyone help point out where I need to further modify the expression to get both fields to show properly in feet?

Thanks,

Robert.

Hello @RobertChaney

A "COGO Error" is returned when there are too many parameters. For example, if Direction, Distance, and Radius are all populated.
It looks like the conversion is placing a zero ('0') if the original value is NULL, instead of keeping it empty.

This can be solved by checking and only converting the units if the attribute is not empty:

if (!IsEmpty($feature.Distance)) cogo_distance = cogo_distance*3.28084;

Add this check for any value that you convert (distance, radius, arclength, radius2)

Please let us know if this solves the issue
