I’m wondering if there’s something similar to the sub-object ‘Edge’ Constraint option that exists in 3DS Max. The closest thing in Blender 2.8 is ‘Edge Slide’ and ‘Vertex Slide’ which does work like an edge constraint, however only allows movement along a single axis. For example, I’d love to be able to use the Scale tool to uniformly ‘pinch’ them towards or away from each other.
This is what it looks like in 3DStudio Max:
I found I can somewhat mimic the results of an edge constraint by changing the Transform Orientation to ‘Normal’
This seems to work okay on a single set of edges within an edge loop…
… but does not allow me to do the same with the entire edge loop as per the above 3DS Max example
Also, If I scale in the edge sub-object level instead of vertex, the edge angles go out of whack for some reason. Strange behaviour
