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.

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.

NoteSelf-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.

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.

New Boundary Patch options

Two options are added to Boundary Patch.

  • Automatic Edge Chain Provides a streamlined workflow when you select multiple edges. You can include edges that are not tangent.
  • Boundary Patch Create complex shapes using the added weight factors for tangent and smooth boundary patch types.

The following image shows the effect of using different weight factors. The image on the right uses the maximum weight factor of 1.0

Fillet success

In previous releases, if one edge in a fillet selection set failed, the entire fillet operation failed. In this release, any blend failures open a dialog box with the option to fillet the successful edges.

After you fillet the initial edge selection, you can repeat the operation using the same size radius. This action usually blends more edges.

In the model used in the following image, an additional 17 edges are filleted after the first 142 edges are successfully filleted.

Work Point on a sphere

In previous releases, a sphere was not a valid selection to locate a work point. You can now define a work point at the center of a sphere.

Derived part color override

In previous releases, you were not able to change the color override setting when you placed a derived part. An edit after placing the part was required to remove the color override.

In this release, you can keep or discard the source component color override when you place a derived part.

The override setting is persistent between sessions and is respected in the Make Part and Make Component commands.
