Hello Misarah,... I know we have gone over this in the forum but I can not find the thread?...
Probably not what you're looking for but here's a simplified example making a quarter sine boundary surface and patterning..
Thanks a lot for your help.
It's still too early for my brain to do maths.. is this what it's supposed to look like?
Thanks for your reply. and sorry for the late response. The profile was suspended i couldn't log in but now it is ok.
so how this can be drawn?
If you look at the image I posted you can see the lines chosen to create the boundary surface.
Your equation is z = k * sin(x) * sin(y)
first work in the x direction.
Lets start at x = 0. and solve z = k * Sin(0) * sin(y) ..
But wait a minute what is sin(0)? Oh it's zero so we don't need a fancy equation.. just a line.
Sin(PI/2) = 1 so if we work on that plane, we can use equation curve to z = k * 1 * sin(y).
Does that make sense?
Rinse repeat. then use the lines and curves to make a surface. You may see some symmetry to make things easier.
Thanks a lot for your explanation.
Would you mind send the solid part file to me as a guide.
Sorry, I no longer have the file.
Look again at the solution, it is simpler than it looks. - A grid with sin waves
The hardest part is getting the scale you require correct (choosing k) in your equations.
A simple alternative I can offer to make a sin wave of the required size is to use a surface sweep with twist, then convert the edge onto the plane
Have a go and show us what you've got.
On the forum we like to help, but we don't do it for you
I tried several different methods for this from this forum and other places. The method from April 24th is the only one to give control of the size and shape and accurate results. The posts have all the information needed to make it.
The only thing I changed was that I made the surface bigger than needed and trimmed back. If I made it exactly the right size before patterning then the boundaries did not match up cleanly. This maybe because my equation was a little different.
