Caltic Waves creation

[Zaki]

Hi guys


I am designing a part just like pic below. But I must make each section manually and its making part so heavy.By equation,I cant control the curve or surface as I need. Can any body make it with some other easy way?

Hi,


Almost similiar thing, i need to create a golf ball.


Howto pattern the depression shown below in the picresembles like agolf ball?

Hi Asho


this is not like golf ball, I am facing the problem with creation of sin weave curve. I can easily make it. But as I create all curve and surface manually, it make the part extremely heavy and I cant handle this size as I will design the mold to. I require some easy way to create this.

Zaki,


If you have not already used REFERENCE PATTERN, you may try that. It makes the model lighter.

I tried it man, but got heavier model instead of ligher. anyway, I am doing it and got some success.

I'd be getting some feedback from your toolmaker about now... on how they intend or want to create the texture

I'd sugest using a Variable Section Sweep (VSS) of one revolution around the sloped cylindrical trajectory.

From your pictures it looks like the raised feature can be created using overlaping sine functions.

For the the feature shown that wraps around as shown with the blue curve in your pic, you can have one VSS that produces the bumps with a section relation that gives the height of the bump as

A Amplitude of Sin Wave
N Number of bumps
O Offset value to give you gap between bumps

VSS#1
sd# = A*sin(360 * trajpar * N/2 )-O

VSS#2
sd# = -A*sin(360 * trajpar * N/2 )-O

Do the same thing in the vertical direction for the other bumps using a datum through the cylinder axis and a point on a spiral curve used to create the first VSS features.

Hy Michael


thanx for your help, I am going to try this out.

Zaki,


about two years ago I faced a similar problem. To lighten the file, I rember making a reference pattern (or is it grouping and patterning...? my memory fails me).


For the FIRST pattern, ensure that it is IDENTICAL and not general or variable i.e. if it suits your design requirement.


According to PROE HELP this is easy on the syatem.
