Mate cylinder to curved sweep 1

[VRxdcr]

In an assembly, I'm trying to apply a concentric mate between a cylinder (part 1) and a curved sweep (part 2), but not having much luck (I'm attempting to model a wire that wraps around a pin). The sweep profile consists of a circle. The sweep path begins with a straight line, then transitions to a tangent arc with an included angle of 270 degrees. It seems SW doesn't provide a mate option to have the cylinder pass through the center of the resultant 270 degree torus. As a workaround, I added to the profile sketch a small flat surface which would become the inner diameter of the "wire" after sweeping, which then allowed a concentric mate between the cylinder's surface and the small flat surface of the torus. Am I missing something obvious? I'm new to the program (SW2004) and new to this forum (extremely helpful, thanks everyone).

You need to use Planes to make a mate like this. Use the planes that go through the center of the sweep feature and mate them to the planes that are center to the cylinder. If you don't have any make some.

The mate type will then be Coincident between each plane.

Scott's right. You can also place a point at the center of the circle (that the wire creates) on your plane there. Make that point concentric with your cylinder and make the plane perpendicular to your cylinder axis.

If you need it, you can add one more mate to prevent roatation of your wire form around your cylinder.

Another option is to "show" your path sketch, then add a concentric mate between the 270 deg arc in the sketch and the cylinder
