Fixed several issues in which toolpaths were not being invalidated when specific parameters were changed: Safe Z, Origin or Chuck Front in a turning setup, Entry and Pre-drill positions, Bottom Height 'from selected point'.Fixed an issue in which the stock contours preview was incorrect when another tool orientation was selected in the operation.This can be used to correct expanded gun-drilling cycles. Post Processor: A new variable 'machineParameter.spindleSpeedDwell' has been added which specifies a dwell time in seconds when the spindle speed changes during a drilling cycle.There are also corresponding 'axis.getReset' and 'tReset' functions. A 'reset' parameter has been added to the createAxis function, which can reset the current rotary axis position to zero prior to scanning the section for the optimal rotary starting position.New functions 'section.getModelOrigin' and 'section.getModelPlane' were added to provide access to the work coordinate system of the CAD model.A warning is now issued if you edit a machine configuration that is being used in multiple setups, since the changes you make will affect all setups that reference the machine.CAM functions for 2D Profile are now enabled when the Flat Pattern environment is active in Inventor.Many icons in the user interface have been refreshed to improve constistency with Inventor.The HSMEditor has been updated to the latest version for the 2020 release.

This release contains a number of important fixes and improvements, as identified below. This document covers all three Inventor CAM products: Autodesk® Inventor CAM™ 2020 Release Notes
