Nose, help

Nose, help

Nose, help

(OP)
can some one help me, how would be best to create a nose cone (formula 1 style) would it be to create a cross section and extrude....if so, can you sweep with three guide line to get the profile of the cone?? thanks

RE: Nose, help

The problem with that method is that a nose cone is not constant in width. They taper in from the sides and down towards the tip. My guess is that they are designed with free form surfaces and then thickened.

I suppose you could use the sweep for the lemgth and then trim the sides in with a free form surface. Then apply blends to smooth out the shape.

The original 2004 Williams nose looks to be fairly constant in width but all of the others have side taper.

"Fixed in the next release" should replace "Product First" as the PTC slogan.

Im not familiar with free form surfacing as Im quite new to UG, how would I go about doing that??

Thanks for your help guys

Ok, Ive just had a quick go at surfacing and the basics dont look too hard. How do you convert surfaces to a solid model??? Can you blend edges of surfaces

RE: Nose, help

A couple of ways to create solids from sheet bodies:

a) You can thicken sheet bodies to create a solid.

b) You can sew sheet bodies together and create a solid if they completely enclose a volume.

Yes, you can blend surface edges.

great, i have constructed the lines for my nose, but one of the ones Ive constructed I cant get right. Does anyone use msn so i can send a screen print and they can advise

RE: Nose, help

One thing to note:

If the surfaces do not belong to the same body, you cannot use edge blend on them; i.e. two separate extrusions coming together to form a corner like in a box must be sewn together prior to using edge blend.  However, you can alternatively use Face Blend with Trim & Attach All to achieve similar results.

I would suggest reading the documentation for this sort of information.
