Autodesk® Inventor HSM™


Release Notes – 2018.3 (R4) Update

Build / 8 January 2018

Autodesk, Inc.


This document covers all three Inventor HSM products:

  • Inventor HSM Express
  • Inventor HSM Premium (formerly Inventor HSM)
  • Inventor HSM Ultimate (formerly Inventor HSM Pro)

What’s New
System Requirements



The following changes have been made in the current update (2018.3):

  • Added 2D Profile strategy (similar to Fusion 360). #8863
  • Added support for pecking for Turning Profile. You can use this feature to break the chips. #8835
  • Added support for both ways Adaptive Clearing. When both ways is enabled you can set a separate load and feedrate for the opposite cutting direction. You can use this feature to reduce machining time further when roughing depending on the material you are machining. The main cutting direction (normally Climb) will be the preferred cutting direction but the opposite direction will be used when the alternative non-engaging stay down linking would be estimated to be longer. #8734
  • Added support for back cutting (used for Sandvik PrimeTurning) for Turning Profile. #8946
  • Added Flow strategy. #8296
  • Improved stock simulation of simultaneous multi-axis toolpath. #9187
  • Show number of holes being machined for Drill. #8221
  • Fixed issue when selecting a tool from different operation in the tool library did not use the desired feedrates and speeds. #9235
  • Block post-processing if an operation is calculating. #9218
  • Fixed a crash when running simulation of a weldment assembly. #8900
  • Fixed issue where undoing multiple CAM operations wouldn’t refresh browser nodes. #8868
  • Fixed issue where toolpath generation didn’t obey the max number of concurrent tasks set in the CAM Task Manager. #8781
  • Fixed issue where the maximum spindle speed would be overwritten when selecting tool which uses constant surface speed. #8394
  • Improved turning radii selections when using the “Selection” option. #8282
  • Fixed issue where multiple tool entries would be created when copying operations across documents. #7809
  • Using a Spot drill for drilling exposes linear feedrates. #5413
  • Fixed issue edits to an operation parameter will be lost if hitting Return quickly. #8836
  • Shows a progress bar when executing commands (generate, duplicate etc.). #6749

Known Issues

  • If you cancel a rename action in the CAM browser, or accept a rename that doesn’t make a change, you may get into a state where further browser actions (e.g., right-click) menu do not work. To get out of this situation, just press ESC again. #9282
