My goal is very simple, and that is to extrude along the surface of this chamfer either by creating a datum plane that goes through it or otherwise. I'm having trouble getting the datum plane to be both parallel to the front AND through the chamfer. The minute I click the first reference to be the chamfer, the option to add the front plane to the reference set disappears.
This is a picture of the situation. To clarify: the arrow is where I want to extrude my elipses so as to create a handle grip, the direction of the extruded ellipses is parallel to the arrow (not normal as you might think i.e. not going out or into the screen). Can anyone help me?
Have you tried holding down control and clicking both references that you want? Your image is not showing up, by the way. Perhaps upload here if you didn't?
I tried that but like I said. The minute I set the first reference through or tangent to the chamfer, the option for the front plane goes away. Re-upped the image in order to clarify...
Unless I'm misunderstanding what you want to do or what your model is you can't make a plane tangent to the surface you're showing and parallel to the front. You should be able to make it perpendicular though.
1. Where is the chamfer in your picture?
2. You said,

Where is the "front" that you fefer to?
The chamfer is the sloping bit, it extends from the first edge to the second. I uploaded the part as someone has suggested.
I'm sorry if I'm not explaining this too well. What I want to add is handle grips similar to the ones on this:
How can I do that while still keeping the chamfer?
One way to do create the recessed geometry is to create a copy of the tapered surface, flatten the quilt, create a sketch of the recess geometry with a sketched coordinate system in the sketch, wrap it around the tapered surface to get the outer surface curve, offset the tapered surface and project (depending onhow you want the base defined) the wrapped curve onto the offset surface, trim the offset surface with the projected curve, create a boundary blend between the two curves, merge the surfaces, copy the merged surface so it can be patterned, and solidify using the remove material option. For the raised ones you can create the surfaces in a similar way. I can post pictures but can't update the model since I'm not using Creo 1.
