Moi is very permissive but it's better to have points at the same coordinates! ;)

Maybe it's not that you want so don't hesitate to explicite more !:)

Extrude + Trim must make the trick...



I don't seen that you want flat thing...but if it's just for trim Extrude is sufficient
You can of course take a direction of the Extrude if you want...

You can also make Projection by your curve but the extrude is more illustrative and generally
it's better to make trim or Boolean Diff with surfaces than only curves in complex forms... :)

Ps when you send a file of objects better to put them on the middle of the grid than faraway on the 3D Space! :)

Maybe set a cPlane?

There are a few different methods - probably the quickest is to use Transform > Scale > Scale1D. That allows you to choose the direction of scaling so if you pick a direction perpendicular to your desired line in the side view then enter a scale factor of 0 that will do it.

If you want to use the edit frame and "flat" snap you could do that by setting the CPlane to your desired angle.

Also you could rotate your objects so the direction you want is aligned with the world axis directions then use flat snap.

Or that ? ...
After the trim
Extrude again
Draw a plane by 3 Points
Move it
Boolean Isect
et voilà :)
But don't know if it's that you want! :)

Thanks for all the help.

Is there any way to change the top-right view during split view to be Front and have the bottom-right be 3D?

Sorry no there isn't.

Hello, is there a way to limit what snapping affects or disable an object from being snapped to? Locked objects can still be snapped to...

Hi friend, there's an option to control snapping to locked objects under Options > Snaps > Object snap options > "Snap to locked objects".

Also you can disable different kinds of snaps by using the menu that pops out above the Object Snap button.
