Fixed an issue where a turning profile finishing toolpath with no-dragging turned on and direction set to front to back was machining back to front.

Added the ability in turning profile roughing operations to angle the cutting pass while entering material.

Added the ability to select a grooving tool in a turn threading operation for the machining of Higbee (blunt start) threads.

Added the ability to use grooving tools in a turning profile finishing operation.

Added the ability to use grooving tools in a turning profile roughing operation.

Improved the handling of multiple rest surfaces to be consistent whether they are computed from previous operations, setup stock, or model bodies.

Improved the functinoality to avoid air cutting when machining from a setup stock with undercuts or rest machining from previous operations.

Avoid a case where 2D adaptive would crash the application if the radial clearance value was too large.

In some parts, this caused some passes to fail to generate. The default has been reverted to 'Roll around corner' as it was previously.

Fixed a problem with the 2D Profile strategy where the default setting for 'Outer Corner Mode' was set to 'Keep sharp corner' when the compensation type was 'In computer'.

Removed a (non-functional) entry for 'Additive' from the drop-down list of setup types (#26364) and a 'Position' group from the Stock tab for setups.

Fixed an issue in which the Geometry tab was not displayed in 2D Face and turning dialogs.

Fixed an issue where 'Reorder to minimize tool changes' was not working.

This mainly affected people using a USB memory device.

Fixed an issue in which posting NC code to the root folder of a drive failed.

Fixed an issue in which the toolpath preview was not displayed when creating a pattern.

The following changes were made in an earlier update (2021.3):

Fixed an issue in which toolpaths would fail to generate if the tool name, tool description, or operation name contained non-English characters.Installation WHAT’S NEW The following changes have been made in the current update (2021.3.1):
