create surface help

[Huzway C]

Our designer had an idea. I said no problem.

Now I cant figure it out.

On the ftp /mc9 /ch surface test, is my file.

I got 3 of the 5 surfaces I need.

Can someone please tell me how?

thanks

is this what you want?

[Huzway C]

yes sort of.

I was hoping for one piece.

the top will be cut from 1/8" acrylic and bent.

I dont think the center will be that flat.

[Ocean Lacky™]

I think you'll need more wireframe to define the curvature of the top.

HTH

 

HRM too slow !!!

 

What arc you want on the top? You can just fillet the wire and revolve again...

[Huzway C]

when i cut one out of paper it behaves like Oceans drawing. flater top.

did you just "pick" a radius for the arc?

Interesting how did you place them?

[Ocean Lacky™]

I just created a Swept surface using the 15"rad and two adjoining splines broken at the midpoint. and a Net Surface to fill in the triangle at the top

[Müřlıń®]

I revolved the edge and then projected a spline on the Y...then you have a profile of a curve that you can revolve 120 degrees...you can take that curve and put any kind of a top on it you want.

 

 

Like Ocean says, you will need to define the top how you want it...I just left it pointed because there was no data for that area...

take a look

this is where the idea came from.

Maybe I'll let him buy it.

do I not have "net" surface?

 

Thanks a bunch guys

this will keep me busy for a while.

No. Revolved is the only way to get a tangical result with 9....in this instance..you might be able to do a coons if you do a lot of definitions with wireframes and then trim it, but revolved is way easier...

 

Start off with defining the revolved curve first. Then cut the scallops in the sides...

OOOPS! nope, not in V9. Sounds like a good reason to upgrade

[Ocean Lacky™]

A COONS surface using edge curves on the created Swept surfaces and a point created at one corner of the triangle will yield similar results.

Craig,

Hereis a video link of what I created from the geometry you put up. The dome is created off known points present on he part.Here is the link

I also have X intro to surface modeling up at

http://www.cad2cam.net/mastercamx_basic_surface%20.html V9 will be out next week.

I hope this helps

Steve buddy take a day off. Sunday at 10:30

nice stuff on your site.

I'll be sure to pass it on to the other boys here.

Guess I will cut one to see how the material bends.

that will tell me what i need to do with the top.

This is just a play project. Will post a pic when we get back to it.

thanks for everyones help.

Craig,

Every day is a work day when you teach this CAM stuff. If you don't use it ya know. I like the surface Parts because you do have to use it when all else fails. As a matter of fact I help design a famous Guy's guitar using Mastercam X Surfaces. Surfaces are not as easy as solids to use.
