Hi. I'm trying to change appearance of a face of a specific part in an assembly, in this case the dome face on part HLMP-1790<2>. Note that there'are multiple HLMP-1790 and I'm only interested in changing the second instance (<2>). As shown in screen capture, under 'Selected Geometry', it has Face<1>@HLMP-1790-2 selected. yet, all other HLMP-1790's dome face also turned green. Is this normal behaviour? or is there another way to achieve this?
