Self-intersecting coils
Coils also benefit from the enhancements made in 2014. In previous releases, self-intersecting coils failed. Coils that used a pitch value equal to the profile size also failed. If the pitch is equal to the profile, the coils touch but do not intersect. Inventor now supports both cases.
Note: Self-intersecting sweeps and coils are allowed, but a single face cannot intersect itself. If the profile is a single entity like a circle, split the sketch into two segments. All of the following coil examples use a pitch value of 10 mm which is equal to the profile size.
In the following image, the sketch profiles are composed of multiple lines which creates multiple faces when the sketch is consumed. Inventor can create these shapes without any special treatment.
In the following image, the sketch profiles are circles. A circle creates single face and causes the coil to fail. To resolve the issue, the sketch geometry is split into two segments. The spiral and coil operations are successful.

Self-intersecting sweeps
With the enhanced sweep command, you can create sweeps that were previously considered too complex to solve. You can sweep large profiles along small fillets and bends.
The following image displays examples of previous sweep failures on the left, and successful 2014 sweeps on the right.
Perpendicular surface sweeps
Previously, creating a swept surface using a profile that was perpendicular to a closed G0 (not smooth or tangent) path failed. New sweep functionality lets you create a surface using a perpendicular profile along a closed G0 path.
