Fixed a crash that could occur in some cases when trimming a pocket toolpath.This could include cases where the curves are end to end or where there are an odd number. Added warning messages in blend toolpaths when the drive curves are badly formed.Ignoring the open curves without a warning could produce confusing results for the user. Engrave requires the input curves to be closed. Added a warning for engrave when there are open curves in the input.Fixed an issue where toolpaths would not generate with an error refering to 'Turn' and 'Tilt' parameters, which were not applicable in the context.Fixed an issue for 2D contour in which the toolpath was not calculated using the check surfaces option.Fixed an issue where avoid surface clearance was causing an empty toolpath with unreachable passes.Added information to the log in cases where an adaptive toolpath fails to produce any path because the ramps are too large.

Fixed an issue with rest shadow air cut reduction in pocket clearing that was not working correctly.

Fixed an issue where a toopath did not reach all accessible areas when using holder protection (pull-away) in rest machining.

Fixed an issue in which adaptive toolpaths that were trimmed by holder collision protection were not respecting the minimum cutting radius.

Fixed several additional cases where adaptive clearing failed to calculate a toolpath.

Fixed an issue for adaptive toolpaths where a ramp into pockets without a suitable predrill position was used in some circumstances.

Fixed an issue for adaptive where a ramp diameter close to the maximum possible diameter for a given pocket could cause the application to hang.Fixed an issue in which the adaptive clearing toolpath would not generate in specific circumstances.Fixed an issue in which adaptive clearing unexpectedly reversed the cut direction mid-move, which could lead to a tool breakage.Installation WHAT’S NEW The following changes have been made in the current update (2022.1): This document covers these Inventor CAM products: Autodesk® Inventor CAM™ 2022.1 Release Notes
