Help generating multiplane grooves that can be patterned

Help generating multiplane grooves that can be patterned

Help generating multiplane grooves that can be patterned

(OP)
I'm using Pro/E 2001.

I have a cylinder with a round face at one end that is stepped, the inside diameter being higher than the outside diameter.

The transition between the two heights is along a 3 degree draft face.

I want to add a groove that flows radially from the inside diameter to the edge of the step and then follows the 3 degree face, stopping at the lower face without removing any material from it.

This groove needs to be suitable for patterning.

I can create the groove by itself using two extruded half circles or two swept half circles.

I can pattern the flat radial grooves but I can't pattern the grooves that follow the 3 degree draft, I always get the message that references cannot be replicated or something similar.

Any ideas how I can create these grooves so they can be patterned?

Hi Fawkes,

Are you cutting or extruding?  Why not use a revolved cut or extruding and then pattern based on the diameter and linear distance used at the same time.

The pattern is rotated about the edge (4 -off eq. spaced) so I've used a datum plane created using the angle option so far for extruding and for sweeping but it's the references on the groove on the draft face that fail.

RE: Help generating multiplane grooves that can be patterned

Try to make surfaces (quilts), merge them to a single quilt, then do a cut using the quilt.

You should be able to do a rotate copy of the quilt and then pattern that rotated copy, regardless of how it was created. Then do the cut from quilt on the pattern leader, and reference pattern that.

Hope that works!

RE: Help generating multiplane grooves that can be patterned

I did something similar by using a variable section sweep (surface) defined my path with a graph & equations. Did a surface offset to the width of groove.  Merged them into a single quilt then did a cut using quilt.  And the groove was patterned 120 degrees.

Never argue with an idiot. They'll bring you down to their level and beat you with experience every time.

I maybe able to send you the trail file or menu picks.  I will have to search through my data.

Thanks for the feedback.

I managed to complete the task using different relationships and using 'relations' to mantain association between different dimensions.

I'm not used to using surfaces or quilts but it's something I'll look into in the future.

Thanks for your help.
