Surface IDs keep changing

Hi all,

I am trying to automate fillet nodes detection and splitting the surface as shown in the figure. The code will detect nearest node as you can see in the command window (in fig) and split the surface. The PROBLEM is that surface IDs keep changing after every split and the code is throwing error. Can anyone help me with this? Your help is much appreciated.

Thank you in advance!!

Right, there is no guarantee of new surfaces having a certain ID. You will probably need to use something like *createmarklast

Hi Ben,

Thank you so much for your help. This will surely help me dealing with new ID generation while doing surface splits.
