Question

Pattern

OK, here's the pattern (image attached) - a revolved spherical dimple on a revolved non cylindrical surface. I want the dimple patterned in two directions - very approximately a cylindrical grid - around the revolved surface and along the surface. Easy enough on a true cylinder but keeping the dimple following the curved surface is the tricky bit,


cheers, Sean

OK here's one solution (image attached) I've come up with - which has the added advantage of making the pattern light weight:


Created a (dimension) pattern along a curve (in this case and intersect) on the surface


Create a copy of the surfaces in the pattern and axis patterned the copy feature


Use the surfaces in a solidify. Had to do individual solidifies though for each line of revolves


(In this case the revolve is a cut and I've added the revolve diameter to vary in direction 1)

Hello Sean,

I would suggest that you use a TABLE pattern. I just have done some designs with an inverse dimple (like a golf ball) pattern. This works on non-cylindrical parts like an oval tube like design. Trying to simply use an axial pattern and then pattern that directionally, I would think your spacing between the dimples will change. There is a config.pro (part_table_editor excel) setting to allow you to edit your pattern table in Excel. That makes it much faster to create a table that you can control the angle and offset of your dimples per given position. For instance, your smaller diameter section may only require 15 dimples around the axis, but your larger diameter areas may require 30 dimples.

Also, have you considered a TOROIRAL bend? I just made a quick example using this, but the dimples look a little distorted.

Good Luck,

Project curves on surf. Pattern along curves?

I am modeling a panel with a punched in fan grille. The grille is made up of .115 square punches in a config of 30 wide x 26 high and a .030 space between punches. It takes about 3 mins. To generate. Is there a way to produce it to generate faster?
Thanx in advance

1. Use surfacing to create the shape of the cut.

2. Pattern the surfacing features.

3. Solidify the first one.

4. Pattern the solidify.

Paul,

This is what Donald is referring to.

You can also try to change the pattern to an identical pattern. I believe it's under the 'Options' tab in the pattern dashboard. Identical patterns are much faster but don't work in every instance.

If you are on Creo Elements/Pro 5.0 and above, you can also use:

If I really don't need the actual geometry but just need it on the
drawing, I sometimes create a sketch of the pattern. It looks about the
same on the drawing but regen is much faster.
