I am working on a rigid-flex design where I have a single rigid 4-layer region and a single flex 2-layer region. The 2 layers in the flex region protrude from the 2 internal layers in the rigid region. I have to place a few components on the flex region, but when I click on a component and use the PCB inspector to try and change the component layer to one of the two internal layers there is no option to do so. SW restricts me to only the top layer and bottom layer of the 4-layer stack.
I have defined the two regions using the stack manager, defined my split line separating the two regions, and assigned each region its own stackup section.
Any help is appreciated.
