# Is it possible to alter the direction Cut-Extrudes along an elliptical swept surface inwards towards the center of a swept ellipse shape?

I am designing a wristband of sorts, and I have a swept boss/base for the basic shape of a wristband.

Next, I projected some sketches onto the surface of the elliptical solid and converted them to 3d sketch entities.

Now I am trying to extrude-cut these shapes on the surface inwards towards the CENTER of the ellipse, but I can only select planes as a directional guide. And making a new plane to guesstimate the proper angle of each and every cut seems silly. Is there an easy way to specify the direction/draft of a cut to be aligned with the origin of an elliptical shape?

Thanks,

Gol,

Please see the attached part and image below.  Basically I used circular pattern to repeat the cuts.  I hope this helps.

Ah thank you, I knew there was an easier way!

Worked like a charm, thank you Robert.

Mongol,

Don't make 3D sketch entities. Just use Split Line or Wrap. In older versions of SolidWorks, offset the surface, delete the original surface, use a Boundary Surface or Surfaces to make the side wall or walls, then Knit the surfaces and make the part a solid. In newer versions (2011?) I think that can all be done with one feature after the initial split line.

Yes, have the newer version and the 3d sketch I used in this process seems to have been an unnecessary step.

Thanks for the confirmation Jerry!
