Inner extruding weird shapes [3ds max]

1

I was wondering how you would inner extrude weird shapes?! I know how to inner extrude squares and rectangles, but i want a unique shape to be extruded. I guess i can’t be using the object as an editable polygon for this. So what would i use instead???
thanks!

2

are you trying to extrude like a circle? i think thats boolean modeling…but i dont know it. sorry. try looking that up somewhere.

more like a sort of:


________
|              |
|__      __|
     |__|

that shape. I’ve tried the help files, couldn’t find much on it :-\

edit: hmm didn’t quite turn out how i wanted it to be. I’ll try again. Basically the image above (which isn’t showing up properly) with smooth curves.

lol what kind of shape is that :stuck_out_tongue:

yea i think u should just use boolean :slight_smile:

5

heh, its more in a shape of a wolf head if you put all the lines together, but as you can see, it didn’t quite turn out well :slight_smile:

anyways, how do i use a boolean? the only boolean i know of is true or false :-\

6

select the object u wanna boolean
and then go to compund objects in the create pannel…
then click on boolean and press the button that says operland or something and select the object u wanan cut :slight_smile:

7

hmm, i tried selecting and nothing selects?! There are two operands. One is under ‘display’ and the other says ‘pick operand B’. Do i select both? I tried both, or 1 of each but its still not selecting :-\

8

hmmm its kidna hard to explain :confused:

u should look up boolean in the help file!

i think boolean is kinda like the pathfinder in illustrator, right? it’s where you get a shape and cut it out of another shape?

you just have to overlap the parts u want to be subtracted…maybe.

i think the help file is your best option after all :stuck_out_tongue:

10

well i’ve read the help files, and it seems like it is what i want. But, how do i use it now is the question!? i don’t see where it tells you how to use it :-\

edit:

actually i think the question is, how do i make operand B?! i have operand A (which is just a box) and so how would i make b!?

11

yeah, position the the object you want to cut-away from another and select boolean object from the compounds tab. Click on pick operand B and the target the object your subtracting from. There are 4 options in the boolean rollout and you’d want subtract a-b.

12

Thanks i understand that bit now, but how do i make the operand B? would i just use a line tool to draw the object?! And would i have to have that object the correct depth and everything? If so, how would i do it?! thanks

13

operand B would just be another object. You could make it a box, plane, sphere… basically any mesh object. Not sure if it works with Nurbs though.

14

Hmm, ok. so how would i make operand B an object like the one i want?? What techniques could i use to draw it out?! thanks

15

anyone?! pleease! I was thinking of using the line tool and then ‘lathe’. But it makes it round, and thats the only way i know of so far for making a unique shape :-\

Thanks for the link kei, but i think more of the problem at the moment is how to make that weird shape.

Ok, so i’m trying to make a computer box (yes i’m trying to make a whole desktop :)), and you know the floppy drive, the shape of that. Cause usually those aren’t just a rectangle. So i was wondering what to use to make it (lines? or any other options?). thanks

18

ohh okay…
i think the easiest way would be to draw that in 2d using the spline tool and extruding the shape
then use boolean to cut that shape out of the box :-\ ?

19

Ahh the spline tool, hmm that may work, after i figure out whats slowing my 3ds though :-\

blah, if oyu want a fast way, just make a texture for it in PS and do it that way,simple and fast.
