With the move tool, how come I cant extrude along component normal's, if I have all faces selected?

Lets say I have a simple cylinder I want to give some thickness to, with the move tools ‘axis orientation’ set to “component”

If I just select a few faces of the cylinder, I can extrude the faces along their normals, in effect giving them a thickness, but when I select all the faces of the cylinder and attempt to do the same thing, extrusion is not being performed along each faces normal, in fact the pivot is at the dead centre of the cylinder, and so I end up getting undesired results.

I demonstrate the above issue HERE

This is all in contrast to the Extrude command, which can extrude each face along its normal. This has tripped me up a few times, and I would just like to know what is the critical difference here.

Thank you.

With that functionality you are not moving each component along it’s own normal, you are moving everything selected by the average of the selected component normals.
If you want to move multiple components along their own normals, don’t use the move tool, apply the “Transform Components” modifier, which is on the Poly Edit menu. (at least, I think that’s what/where it is, I’ve got no access to Maya atm, and I’ve not used it for a long time)

Thank you, I came across this name you mention here and there, but I was not sure what it was for, I will look into it and see.

y..you stopped using Maya?? I wonder what package you moved on to, if any! just curious

I haven’t stopped using or moved onto another package from Maya as such, I simply work in a studio environment where our Maya toolset is now almost completely comprehensive and pretty static. As my day-to-day mostly revolves around inter-DCC pipelines, I now spend most of my time in other DCC APIs, like MotionBuilder, UE5 and Substance, etc… I just haven’t had to run Maya much in the last few months is all.

I see, makes sense. That sounds like so much fun… Thats pretty much half of what I want to get up to.
