STL cut only on plane

I am trying to place cut some relatively complex stl files. However, after I perform the plane cut and then go to seperate shells, It also separates small details on the model as well. Is there a way to keep the model as one piece, and only separate along the plane? Thanks

Against doing EDIT/SeparateShells you may use SELECT/Edit/Separate. This converts all selected surfaces to a single separated object.

 

So go to SELECT, click somewhere on the background near to the cut you did before to start the ScreenSpaceLasso mode and draw a line near to the cut. Expand that selection to connected surfaces (either by shortcut E or via Modify/ExpantToConnected)

Now hit Y to separate that selection or run Edit/Separate on this selection.

This is almost exactly what I need. The problem with this however is that after I split it via your advice, my halves are now both hollow. Any idea on how to make it solid?

If you do EDIT/PlaneCut with CutType "Slice(KeepBoth)" and FillType "RemeshedFill" before the workflow above, it should give the expected result. Don't forget to expand the selection to connected surfaces (via hotkey "E" or via Modify/ExpandToConnected) before separating.

I need help with this as now only one half has fill and the other half is completely hollow.

There are different settings in the plane cut tool. Try several different combinations until you get the result you want.
