Vias

6 layer board,

default layers - Top, Inner2, Inner3-v, Inner4, Inner5-h, Bottom (Inner2 and Inner4 was Planes(Shields), but change them to Conductor type, i.e. routing should be possible on them.

Have 3 type of via - Via03_06, Via04_08, Via05_1, added to constraint manager. Via padstack is the same as PCB layer structure.

When I put via during routing, available planes are only Top, Inner3-v, Inner5-h and Bottom. Inner2 and Inner4 does not appear as possible layers.

Is it something in layer structure that I need to change, constraint manager or via padstacks? I try few things, but no change.

Thanks!
