View Full Version : EPS / Extrude Question

09-14-2003, 02:25 PM
I have been trying to follow this tutorial:


I am trying to import this logo:

(available here)

I follow the instructions, and have experimented with different Extrude options. With the different options, including Axis drill on and off, etc.


I seem to be losing the eyeball in the middle when I get the extrude right, or if I am able to keep it, I don't get the surface. It just ends up being hollow.



Any advice on this? I eventually want to slightly bevel the objects and use this in a scene. Any help would be greatly appreciated.

*Oh, and YES I did check the manual extensively.

I tried it and it worked if I chose 'Closed Ploygons' rather than 'closed lines and polygons'. Also you'll need to have the 'Autoaxis drill' box selected.

Hope that helps.

Just a suggestion, but it's worked for me in the past - don't use the AutoAxis Drill option (no offense to cagey5 :D ). Cut the inner poly, past it into the background layer. Extrude the outer polygon. Split the poly face into a couple different polygons, then use the background layer as a template to stencil the cutaway poly. Smooth shift that poly with 0 offset, then use the move tool to move the section back. As far as beveling the resulting face poly, either pick up Bevel++ for $30 or be prepared to do much point overlap clean up....

The reason I skip the Auto axis drill option is that I got used to it - LW gets confused if there are several drills to be made, in my experience....

I mocked it up in about 2 minutes without issue doing the above, so let me know if my explanation doesn't make sense....


p.s. - I didn't have a problem with "Closed Lines and Polygons" option on this one, but maybe that's what's causing the probs with more complicated logos...

Thanks, is there any way to smooth out the segments?

Check "Smoothing" on the Surface Editor. I'm assuming you mean the faceting in the extruded portions (in the modeler screen shot) - this should work with little to no tweaking. If you've got the front poly called the same surface as the sides, the smoothing angle may need some love before you get decent results...

Best of luck and post the render when it's done!

Thanks for the help, I am kind of a newbie, so please forgive the questions.
I have looked in the manual to try and understand what you're referring to. (cutting the polygons). Are you saying I need to cut out the hole myself? Is there a page you know if in the book that refers to this?

I did try the smoothing, in the surface materials - but I am thinking the points are what's killing it. When I smooth it too much, I get a lot of noise in the render too.

Thanks again for your help! :D

Okay - it's been a long day here so please pardon me if I treat you like more a newb than you are... no offense intended!

Check the manual page 24.25 - stencil or slice. Don't bother with the Solid Drill, as that is going to cause you to have to extrude the BG layer, which is one too many steps in my opinion for this piece. Anyway, if you're still getting smoothing errors along the extruded faces, then yes - you've got 2 point polys, or concurrent points. Go ahead and hit "m" to merge all concurrent points, which will make them 2 point polys. Bring up the statistics window ("w" by default) and select all the 2 pt polys and delete them.

If you're running into errors between the sides of the logo and the front, you need to either name them different surfaces or cut and paste to cause overlapping points.

Post a pic of what you've got and we all should know a bit better the situation you're in. Otherwise, feel free to e-mail or PM me here and we can figure out what's going wrong...
