Pattern along a curve

[rodgerandrew]

I have a problem trying to pattern along a curve. Using WF4 M130 Win7 32bit


The curve is a 2Darchimedian spiral generated using an equation (found the solution here - thanks folks!).


I have created a feature at the start of the curve but when I pattern, it won't let me select the curve. I can sketch the curve using copy edge in sketcher and selecting the parent curve - this works OK but I eventually want to project the curve onto a 3D surface and therefore cannot use this technique. I have also tried copying the curve using the approximate solution to ensure it is a spline but without success.


I have loaded WF5 M080 but select doesn't work here either.


Does anybody have any suggestions?

Can't work out what it is you're trying to project, the screw or the patterned features.

Trying to pattern the feature along the curve, which is projected onto a 3D surface

like that, kenppy, but my curve was created in a different manner to yours

ok, it works for this as well.

Thanks Kenpp - I have gone about this pattern in a different way as I need to completely fill the curve with features at a specific pitch. In Pattern, rather than DIMENSION I select CHAIN. At this point it gives the ability to select or sketch a chain - sketch works but is only good for 2D but select just doesn't work either for a 2D or 3D curve.


I am now having a close look at yours to see if I can adapt it to do what I want. My feature is a cut into the surface rather like a golf ball.

I don't know if this is what you are looking for or not, but I thought that it was pretty cool. There is a parameter that drives the number of divots, and also relations so that they are evenly spaced along the curve. Hopefully this helps you somewhat.





To conserve file size, I suppressed the group of patterned features.

Thanks, Greg


It is pretty cool and seems to do what I want. I will have a play..............
