Hi all,

Just a query on Create Underpass tool if anyone has come across the same issues or has any ideas what could be happening:

Using ArcPro version 2.6.1

Layer Ref Scale 50000K

So to start off this is my initial parameters for the tool

That gives me the following output:

The moment I try to improve the masking by increasing the Margin Across, Margin Across or Ref Scale in the Tool Environments undesired masking appear

The following output I just changed the ref scale to 2500 and the square white mask appears

To get the mask to make a clear underpass marked in yellow the parameters had to be increased to 25m Across 25m Along and Ref Scale 20000 but this comes with the expense of even worse masking at junction marked in red.

Having the same issues in Arc Map 10.8, please ignore bad symbology just testing roughly in Arc Pro.

Testing in Arc Map I was finding Arc Map crashing out after I run the tool and refresh my output so easier to test in Pro.

Any help would be welcomed.

Thanks,

Tauna

The Cartographic Coordinate system seems to be unspecified.  Is there a reason?  It is used 

to determine the size, extent, and spatial relationships of features when making calculations

which may or may not make a difference.

Hi Dan,

Thank you for your response, no reason for not having it in I have tried with and without co-ord system and does not improve things:thinking_face:

The tool seems to work great when layers are set for 25k ref scale and the tool environment is set to 10k but the moment I set the layer to 50k and change any of the parameters things start to deteriorate.
