How to disable 3D Solid highlighting when drawing over them?

[M76]

I'm about to go crazy, but I cannot figure out how to prevent autocad from highligting 3D Solids while drawing.

SELECTIONPREVIEW = 0 works as long as no command is active, but as soon as a drawing command is active it starts highlighting 3D Solids under the cursor preventing me from seeing the point cloud I'm trying to extract.

Is there no way to disable this "feature"?

 

Of course I can hide the solids while trying to draw, but that's a hassle I'd rather avoid, and besides it prevents me from snapping to the solid when needed.

 

Thanks

In the Options dialog, turn off both preview options to disable highlighting.

That's the same as SELECTIONPREVIEW 0, it only disables it when no drawing command is active, so the exact opposite off what I need.

When I have them both disabled, there's no highlighting during commands. I'm using Autocad 2018 though. Maybe it's different in Map 3D 2015.

If you lock the layer (LAYLCK) you have the solids on, they will not be highlighted.

NVM I found it, there is a  system variable called HIGHLIGHT setting it to 0 does what I wanted.
