extrude problem

[isaac_cm]

hello,

I was modeling a chair and I tried to model the back legs and begin extrude faces by selecting the first editable poly in the stack - I have the stack like this : edit poly , tubosmooth, edit poly , tubosmooth (see pic)

 

 

but the problem when I select the last turbosmooth in the stack the model get missed up (see pic)

 

 

any advice ?

 

thanks

your problem is you have an odd looking stack. i wouldnt have 2 turbo smooths, and not in that order if i needed to.

 

what is the 2nd edit poly modifier doing? when you modify the lowest edit poly, it will mess up and edit polys further up your stack.

the second one for adding a crease to the chair, the order I use is the same used by the digital tutor instructor I dont think he is doing wrong - but you did not tell me how you use turbo smooth.

[dean@pikcells]

ok, i only add turbo smooths after all the edit polys.

 

you need to make your extrudes first, then add your crease, then turbo smooth.

I will have to delete all modifiers in the stack and redo the work, is there any other way ?

 

Thanks

[dean@pikcells]

just delete your turbo smooths, so you just have a basemesh. then convert to edit poly so your creases are there. then start extruding.

ok thanks

but why the model behave like this , why not retain the same shape is it a defect with Max ??

[dean@pikcells]

no its not a defect. its because your 2nd modifier is dependent on the edit modifier below it. for example, if you extrude a face in the 2nd edit poly, then go back to the 1st edit poly, and delete that face, how would the 2nd edit poly extrude that face?

ok, this is a very simple way of explaining it, and its more complicated than that, but it's a logical way of working.
