how to trim alot of cruve by outside closed cruve

Here is a python script that should help…

To run, copy the .py file below to your desktop (or somewhere else), then type RunPythonScript, browse to the file and hit open. Follow the command prompts. You can trim inside or outside of multiple closed boundary curves.

MultiNestedBoundaryTrimCurves.py (4.1 KB)

You can also do this “manually” without the script by starting Trim, selecting the trim curve, then use one of the various selection methods to select many curves to trim away at once. Among the useful selection methods here are SelBrush, SelFence, and normal or crossing windows.
