poly extrude - unwanted split !

[lowkey]

the strange thing though is that if i apply the extrusion on a different face everything is fine ...

[lowkey]

my question now is :

how do those faces differ and how do i get the right face extruded without that annoying split ?! :shrug:

So what are we looking at here? Is it the interior faces that are created when you extrude that are giving you a problem? If that's it, it's not a bug or anything, it happens because you are extruding a face with an open edge. You need to just go in a delete the interior face.

[lowkey]

well, to be more precise ... usually after i perform the extrusion, i delete the unwanted faces, which have been created on the inside and - like in the latter example - the surface merges like i want it to.

on the first picture polygons stay seperated, though i already deleted the interior faces.

i want those to merge ! :hmm:

mmmh
I'm not sure I understend your problem.
Maybe you can turn on Keep face togheter tab in the channel box.
If you have these unwanted faces only working on the simmetry axis, I really don't know what you can do :P

E-byez !

If I understand you correctly you get a polyface on your lowres-cage, facing towards the mirror mesh, and this is a face you don't want, so you have to delete it after each extrusion, to make the both higres meshes to fit. Am I correct? I run into the same problem, you wanna keep the side of the lowres mesh open towards the cloned side.

I don't know how to do this, it buggs me.

[lowkey]

nope, always having to delete those faces on the inside is not the thing, which buggs me ! ( though i find this very uncomfortable either )

the problem is that the extruded faces won't merge like they should, though i deleted the inside and though it works on other faces on the cage.

:shrug:

upps, now i see why people don't understand ... i'm such a dumbass ... :wip:

i accidentally put in the same screenshot twice instead of one showing the problem and one showing the wanted results !

i'll post it later on ...

sorry for the confusion

:hmm:

[lowkey]

here we go ... :thumbsup:

That face has it's normal directed, not paralell to the other surface, that's why you get that gap. If you simply press extrude once and the use themove key instead of using the manipulator for the extrude, you can move the ne face paralell to the other surface, to maintain continuity.

[lowkey]

thanks, man ... finally i got it ... but ain't there a way to prevent both halfs from overlapping or leaving gaps between each other while moving ?!

something like a "snap-to-surface" or "collision-detection" ?

or isn't that of much importance, when stiching those together for the final model ?

[MCronin]

When you use the extrude tool, you need to click on the little blur dot on the manipulator to switch coordinate space, then drag foward in Z and the faces will stay toghether.

[lowkey]

alright ... thanks a lot, i never noticed that "little-blue-dot" on the extrude-tool ! :thumbsup:

now it works ! :beer:
