The file is a QR code svg.  Everything shows in preview but only the box part
is rendered.

// Basic square coaster -

translate ([-52,-53,0]) resize([90,90,0])
linear_extrude(height = 2){
import(file = "/home/ray/stupidPeople.svg");
}

difference(){
cube([100,100,4],center=true);
translate([0,0,2])
cube([94,94,4],center=true);;
}

I expect resize() to z=0 renders as nothing.

Made sense - so I changed it .  No effect on render,  made it bigger on
preview...

Oops, RTFM.

Can you share the .svg?

Workaround...

Each section will render by itself so I am creating 2 .stl's and merging
them in the slicer.  A pain but working for now but I really would like to
know what I may be doing wrong.  Thanks for trying to help.

I'm no expert in SVG, when I just do

linear_extrude(height = 2){
import(file = "stupidPeople.svg");
}
cube(20); // forces CGAL render

I get

Compiling design (CSG Tree generation)...
Rendering Polygon Mesh using CGAL...
ERROR: The given mesh is not closed! Unable to convert to
CGAL_Nef_Polyhedron.

That could be a few things, but I think the problem is the QR code has
2d corners which meet at a single point.

They are non-manifold.

A work around is to use offset() which will change the just-touch into
just-embedded.
It takes longer to render.

// Basic square coaster -
translate ([-52,-53,0])
resize([90,90,0])
linear_extrude(height = 2){
offset(delta=0.001)
import(file = "stupidPeople.svg");
}
difference(){
cube([100,100,4],center=true);
translate([0,0,2])
cube([94,94,4],center=true);;
}
