unable to route , showing DRC cursor

Hi,

I am trying to connect a part to chassis ground and Allegro is not allowing me to make the connection for some reason. Here are some pictures to help:

The first picture indicates that there should be a connection between E4 and Chassis Ground. After I hover over it though it gives me the DRC cursor.

The second picture is after I try to route these 2 together.

I click on it anyway and the netlist trace is still there even though I tried to route the 2 together. Any ideas why this is happening?

I also got another unrelated question and hopefully It's ok to ask it along with this if not then please disregard.

This board is a 4 layer template and I am using it to create a single layer board. If I go to setup -> cross sections It looks like I can add layers on there but I cannot remove for some reason. I can get around this by only generating gerber files for the layer that I am using and disregarding the rest. Is there a way of turning this into a 1 layer board?

Note : this is PCB EDITOR version 17.2

Thanks all.

Neil Mustafa.

Hello Neil. You've posted in a forum for pre-silicon functional verification. Please can you move your post to one of the PCB design forums: https://community.cadence.com/cadence_technology_forums/pcb-design/f
I tried to do it for you but haven't got permissions to do it myself.
