Snap while extruding

[Absinthe23]

Hi,

I'm very new to Max (I've just moved from Blender). I'm not able to find any info about this but excuse me if it is an old subject...

When extruding a face on an editable poly the snapping doesn't work. I've made sure all snaps are on but the face still moves freely. Am I missing something? Should I be using the extrude modifier on top of the edit poly?

Also, is there a way to snap by percentages instead of units? Blender has a feature where you can extrude a distance which is equal to a percentage of the size of the connected faces which makes for some nice organic looking shapes.

Thanks.

No, you're not missing anything - Extrude, and some other similar functions, do not use snaps. You can tell because the Gizmo changes from the normal one with 3 coloured axes to thin grey/red ones - same as you get if you turn the Gizmos off. Easiest is probably to drag them out, right-click to cancel the Extrude, then grab the correct gizmo axis and snap them into place.
There are a few things which use percentages - Scaling does, as does animation with a Path Constraint - but the vast majority of things use Units. Remember that there are things in Max which rely on the objects being the correct, real-world, size, so percentages wouldn't always make sense, even if they were available.

Thanks Steve, nice and clear.

I wonder if there is a script that can auto snap while extruding without having to exit extrude mode as you described...? It's one of the things I miss most about Blender, extruding clean geoshapes is very quick. Off to do some research...
