Negative Tire Tread Pattern

L

I am pretty sure this issue has been discussed more than a dozen different times. So, a simple referral to another post would be welcome too. (To spare all ye regulars the trouble of repeating something, lol)

I am creating a tread pattern for a streetbike tire. I did a dirtbike tire (with the raised tread pattern) but of course, that's simplistic. And just as well, is not a streetbike tire which is what I'm trying to do.

For the positive tread for the dirtbike, I was using a datum plane. And then i went back and removed excess material so that it followed the radius of the tire.
Since I'm creating negative space (remove material) for the streetbike tire - this is where issues arise. I haven't ventured too far in the world of datum curves, etc., so I don't know if that's what I should be using. (??) Or if i'm going about it completely wrong.

So... what would be the proper way to create negative space on a curved radius?

(A tire's thickness is 10/30. New tread on a tire is 6/32 deep.)

Thank you.

Edit: My apologies.. Using WF4.

Thank you, much appreciated. I'm a student at the local community college going for my drafting degree. They only offer the Pro/E Fundamentals class which I've already taken. (last fall semester). I have a 2 year student version of WF4 so I'm trying to retain what I learned as well as trying to learn all that I can. We never even ventured into the surface modeling and analysis stuff so I feel like there are a lot of areas still left untouched.
As a personal project (to gain knowledge, and to strengthen my weaknesses) I'm trying to Reverse Engineer a friend's Kawasaki Ninja ZX10R.
Started on small stuff; disk brakes, rim, rear shock. I know I need to start with the bases first (frame, subframe, and swingarm assembly) but the bike's in the shop for a week so I'm having to start with what dims I do have.

Anyhow, sorry for the long drawn out explanation and thanks again.
 
Cool projekt LindsayK , are you planning to use topdown? skeleton? dont forget to upload some pics !!

I love motorcycles.I could use that frame your going to model for a talk Im doing at the Pro/E user conference in Orlando on cabling harness design.
 
'Ello Tobias, I'm planning to use a skeleton model.
And I would love to upload pics. Once I can figure out why every time I try the "Print Screen", the mouse cursor just blinks at me and nothing happens. (Surely there's another way around that?)
With the bike being in the shop for tranny issues, if the mechanics could have let me back there; I could have had full access to a bare ZX10 frame which would have been really beneficial, but that's not the case. So I've been researching on the frame features to get a better understanding of the design (concave component is now convex), as well as looking at parts catalogs to get a look at the inside cavity.

Design-Engine, when is the user conference?
 
Thanks Sip. I'll definitely try that out.

I was fiddling around with it earlier. Realized my width of the rectangular plate needed to be narrower (came out too wide after the toroidal bend, unless I wanted a drag tire, lol.)

Wish my computer was a little faster - feel like I'm drawing in slow mo'.
 
Lindsay, if printscreen dont work, try "zapgrab" from http://www.zapgrab.net/ , its a freeware that works great. You just pick "grab" , drag a box of what you want to capture, and then paste it in "paint" or word or in a mail something like that....easy and simple. About the torodial bend, need any help whit that?

Ah, thanks Tobias; that was getting to be very frustrating.
Hmm, I think I got it figured out. Though I'll admit, when it asked for the coordinate sytem, I was a little thrown off until I looked through the old archives and found out what to do. Looked at posts back in 2006.
When I had created the dirt bike tire, I just created a tire profile and revolved it. Created my tread on a plane, extruded. Created the side wall by chamfering. Then assembled it with the rim.

But with using the toroidal bend.... I guess my next question would be in creating that side wall? Would I use the warp feature before the toroidal? (Does anybody ever use the warp....)
