Is there an equivalent to BooleanIntersection that does not union the output?
what result would you be expecting?
the intersect command would return a curve from the resulting intersection-
boolean split would return the parts split into their respective sections.
for all boolens you can choose to delete or keep the inputs.
The frame example I showed before is oversized. I want to trim all of them to size but not merge them together. It’s about 200 of them.
I am not seeing any example in this thread?
It was the previous thread on extrusions.
Hi @miano
As always, post a file and post a clear explanation of what you are trying to do. Did you try out BooleanSplit as suggested by @theoutside? From your vague description, I think that might be what you are looking for.

there is no way for anyone to know that 
please post your examples here so each thread stay on topic
I’ve trimmed multiple objects with a single object before. While Trim is the obvious command to use I generally prefer to use Split. The entire process should take several minutes at most. There may be a quicker method once you find it but you will spend far more time locating the method and learning how to use it then if you just go ahead and use Split.
Start Split
Select the oversize frames as the objects to be split. If they are on a separate layer(s) use Select Objects or Select Sublayer Objects. Another method to select the frames is with the cursor using a crossing box. If you do so in a perspective view you can rotate the view so more frames can be selected with a single crossing box. Or just select each frame with a mouse click in succession.
Complete selecting the objects to be split.
Select the hull as the cutting object.
Complete Split
Select and discard the unwanted portions of the frames. A crossing box is usually the quickest way to do this.
