NX 9 - Put Section Hinge Line on a hole that is on a curved surface

NX 9 - Put Section Hinge Line on a hole that is on a curved surface

NX 9 - Put Section Hinge Line on a hole that is on a curved surface

(OP)

I have a bearing, like a donut, that has a hole drilled from the OD, radially inward - at 45 degrees off the horizontal joint. When you look at the Top View, of course, it is an ellipse (a circle that entered a curved surface).

I want to cut a section, using that hole as the hinge line location. No Snap Point seems to be able to figure out the middle of the hole. There is no way to grab the cylindrical face, as far as we can tell to infer it either.

A 3-D Centerline symbol WILL go in (it figures that out with the cylindrical face) but the hinge line cannot be connected to that either.

Thoughts?

RE: NX 9 - Put Section Hinge Line on a hole that is on a curved surface

You will have to include a point in the model so that it can be referenced in Drafting. And while if the curve was truly an 'ellipse' its 'center' would have been selectable, however, if this was a hole piercing a non-planar face, then the resulting edge would be a closed-loop spline and not an ellipse.

Try defining your section from a view which shows the length of the hole (hidden lines). You can then used one of the holes silhouette curves to orient your hinge line.
