| Extrusion then smooth problem |
 Tibsy |
Hey!
I am having a problem that I cannot figure out.
I'm a newbie to Max, so if its a daft or simple Q - Apologies.
Basically, I am trying to extrude a curved shape from a floor, I mean imagine your basi flat floor, and then from that, extruding a new hight level (about 150mm raised) where the floor has one side that is in this shape: ~
Whenever I extrude, I get the shape, but when it comes to smoothing it looks a mess.
I've tried with box/extrude. Chamberbox/extrude.
An ideal solution would be if I made chamberboxes to sit on top of each other - but how can I make the chamberbox edges curved so its all smooth?
Thanks for your help
If the above is babble, I'll post some pics to show ou what I mean
Cheers

the above is babble im afraid, ill help you out if i can get my head around what you want.
the main thing to know how to do after extruding is using hte chamfer tool to keep the edges sharp, but throw up a couple of images and ill help you out.

Here you go

Its so I can create two levels on a floor.
I've applied MeshSmooth to this, but you can see its not smooth around the edge.
For this image, which I jsut did V Qucikly, I know there aren't many verticies, but even I was to segment it 500x500, the same thing happens.

yeah your just goping about it the wrong way thats all
from the look of hte picture you doing this...
then extruding faces that roughly make a curve....
yeah?
this is a much better way
1.draw a plane object, 2segs high and however many segs wide you want, (i used 24 but thinking about it you only need about 6 if you are smoothing it.
2. over the top view it drew a refernce spline the same curve as i want the step to be.
3. then convert the plane object created earlier into an editable poly (select and right click the plane, then choose 'convert to' theneditable poly). and in the top view again choose vertex sub object mode (press '1' if the plane is stioll selected) and drag all the vertices down to meet the spline curve thus mimicking the curve). should now look like this
4.now sleec the faces in polygon mode and extrude by group to get this...
5.select the bottom row of polys and extrude them agan by group
6.as you can see the front and rear edges arent straign so while you have the last set of polys selected look down the modifiy panel for the small square button with X, Y and Z in them. these align the selection to one particular axis. the one i used here was the Z button but it may need a different one depending on how you drew this up.
go into border mode and select the rear open edge (it doesnt have a polygon in it at the moment its just an open hole) and click on the same 'Z' button as before then click the 'cap' button to seal the hole.
you should now have this
7. as smoothing modifier rely on 4 sided polygons you will need to connect these back vertices together like so.. (using 'connect' and 'cut' in vertex mode)
8.you done apart from refining the edges using chamfer so it doesnt come out so blobby. heres a pic of the direction you should be going with chamfer
hope it helps

Hey!
That is Fantastic!
I got most of it, until you got to the bit abuot chambfering..heres a pic of where I'm at.
How did you get the back of your object straight? And not following the shape of the curve?
Last thing, do I do the same thing when I want to add a new curved layer on top? (Curves are different for each layer?)
Thanks alot mate! you've beena GREAT help!

Select the line of vertices you want to be in a straight line. Then non uniform scale them down perpendicular to the average direction of the curve.

Hopefully that makes enough sense for you to figure it out. :)

step 6 above is a much quicker way to go about this problem. the x, y, and ,z button in themodify panel rollout are design for this exact job and are precise too. select the end faces/vertices adn click one of the buttons, if it doesnt go right undo it and try the next one.

Correct me if I'm wrong, but wouldn't it have been easier to extrude along spline to get the shape?
