divide/ split a plate element in the physical modeler by using reference line

Thank you again for adding some context. However regions also exist and it is possible to define different attributes to regions on a surface such as thickness, material offset and loading.

Thank you for the reply..

Yes, the plate is meshed automatically considering the reference line. But I would like to bifurcate the entire plate into 3 regions say bottom region, middle region and top region and add into different groups in the physical modeler itself. This will help to me to extract the results seperately for 3 groups and make 3 different designs for for 3 region. (i found it easy to create the groups in physical modler than in analytical modeler)

similiarly, i can provide different thickness if i can divide a single plate into multiple plates using refernce line in above example.

Thank you for posting this idea. I would like to understand a little more about the motivation because the inclusion of a reference line across a surface essentially divides the surface and will be meshed accordingly. Take for example a wall panel which does not have any dividing reference line, but only a few key nodes that will be used thus:-

This meshes as:-

but put a reference line across it, you now have essentially 2 meshes:-

Is it that you want this because you are looking to somehow fold along the reference line and hence the two surfaces are in different planes? Or some other reason?
