projecting a shape on a curved surface

I'm desighing a cyclindrical bearing that has an oil groove on the inside of the cyclinder. The groove has a triangle shape leading from a thru hole. How can I project this shape to the desired surface?

You can't sweep the triangle profile around the
ID? The profile has to be on a plane perpendicular to the path. If I understand
what your trying to do that is. Don't think I understand where the triangle is
that you're trying to project. Normally to sweep an oil grove, I would project
the ID, make a perpendicular workplane for the profile, project the endpoint of
the path and draw the triangle profile to sweep.

I am probably out to lunch but I was getting the impression he might mean
the path is a triangle?? I was having a hard time envisioning why it would
be like that, it though so I am probably wrong.

Either way ... I have a hard time envisioning a triangular oil grove as well
... maybe the through hole is triangular ... I was just guessing;
couldn't really see what the application might be. If he needs more
information, I'm sure he will post back.

The path of the oil groove is trianglar. Where I'm having problems is I don't know how to project that path on the ID.

The path is a triangle. I don't know how to put that path on a curved surface (I.D.)

Can you zip it up and post it to CF? It would
probably clear things up ... for me anyway. I put an example of
the way I see it in CF under Oil Grove. Is this something like you
want?

The triangle is the path the groove takes. It follows the inside diameter of the cyclinder. I need help to insert the triangluar path along the cyclinder's ID.

Larry: I'm new to the discussion group. What is CF? and how do I get there? I can email a dwg.

CF is customer files. Here's a link to both the
NNTP and the WebX readers. I put an example in CF under Oil Grove that you can
have a look at too.

Do a revolve extrude.

Have a look at CF of Oil Groove-1.

Have modified Larry Caldwell file and added a triangular

oil groove to the part.

Not sure if that is what you want, let me know.

See CF under yours for a model "oil tri g c" uses
extrude to surface. Change d64 and d65 and update, not to much mind. Simple and
crude.

See "oil tri g b" for a more accurate model but will not update well and
has some minor errors. After opening files pull the EOP (red cross in browser
down to bottom of file) to open, good luck.

Another file in CF "oil tri h" is probably the
simplest giving good form, using a 3D path and sweep. Though is limited to
angle of surface covered on face of bearing.
