How to use trim with depth?

Hi,

A very new user coming from Freecad.

I've got a complex surface (a lens) which I'd like to "chomp" or trim both fore and aft. You can see that I've created a planar surface where I'd like this to occur. Using the trim tool I can successfully remove all the parts of the lens forward of the planar, plus the planar itself.

The problem is the planar has a curve in the top left corner and I'd like to remove that part of the lens from behind the planar. In Freecad I'd have extruded the planar into a solid, extruded the lens a little and then boolean op'd the solid's to get the difference. The second picture pretty much shows what I'd like to remove.

I've tried doing a similar action in Solidworks using Thicken but at that point trim doesn't work.

Many thanks
