Sorry for the late response. Lost track of this item.
When I am building a Hex-dominant Parametric mesh and I add a surface refinement the first time, all is good and I can select the face for a refinement. However, if I want to add another surface refinement after I already ran a mesh (like iteratively adding refinements to keep core hours down for early mesh iterations, then I can no longer select a surface or volume for the new refinement. This also occurs when I try to change the surface of volume selection of a surface refinement tat worked on the first mesh iteration.
Before and after screenshots attached. Notice how the x and the slider button are gone. In the After pic, i can no longer select faces or volumes. Am I doing something wrong?? I never ran into this before the change to the selection tool.
