By default, when trimming or extending in an Autodesk Inventor sketch, all geometry will be used as a boundary to trim or extend to.
It’s worth knowing how to pick the geometry you want to Trim, Extend or Split to. I would also like to show you how to quickly toggle between the Trim, Extend and Split commands.
Global Trim
All geometry can be trimmed to.
Holding down the ‘Shift‘ key will toggle between ‘Trim‘ and ‘Extend‘.
Trim to selected Geometry
If you want to trim or extend to a specific boundary, hold down the CTRL key after selecting the trim or extend command and pick your boundary geometry. Right click and pick ‘Continue’ to confirm your selection and then pick the item you want to trim.
Holding down the ‘Shift‘ key will toggle between ‘Trim‘ and ‘Extend‘.
Changing commands – Trim, Extend, Split
You can toggle the command between trim and extend by holding down the ‘Shift‘ key. You can also access the ‘Trim‘, ‘Extend’ or ‘Split’ commands by right clicking at any point whilst in the trim, extend or split commands and picking from the shortcut menu.
Changing from Trim to Extend and back by toggling the SHIFT key or picking the Split command from the context menu will save you countless picks and clicks whilst preparing your Inventor sketches.
I hope that you found this tip useful!
