Hi Rich, so making a change to the Trim tool to automatically trim out the area where you clicked on would work great for trimming lines but would unfortunately have a bad side effect of making it more difficult to trim surfaces in many cases.

Currently the Trim tool is meant to be a multipurpose tool that can be used for either trimming curves or trimming surfaces, and especially for the surface case it is much easier to be able to see and select the actual cut up surface fragment pieces rather than just trying to guess at where they will be on an uncut surface that you clicked on as would be the case in the system that you're describing.

Also with the current workflow of having a fragment selection step it allows for the option of selecting the pieces you want to keep rather than the piece you want to discard - that can also be helpful in situations with surfaces where the pieces you want to remove are submerged within other objects.


However, I think a good solution would be to have some kind of alternate Trim command, something like "QuickTrim" that would behave like you describe, I think that will be something that I'll add in the future which would be useful for kind of 2D production drafting trimming where you want to streamline the number of steps.
