How does "Subtract" really work?
-
Hi all, I'm new here
I have a kitchen and I want another sink. I want to subtract my sink so that the hole is placed.
But Sketchup keeps saying that the components are not solids. Anyone who can help?

Create a box with the shape you want the hole to have. Make a group or componente from it. Dive it into the counter. Subtract the box to the countertop. The hole is created.
A box turned into a component/group is a solid. A sink and a countertop, might or not be solids. If it is a solid you can use Solid tools.
Search for info on Sketchup Solids and then search for a plugin called Solid Inspector.

Only if you are a lucky owner of the Pro version (it's your case) else you must make the boolean operation by hand!

in your skp, the top is not a 'solid' because it has no bottom, it's just a skin...
the sink is also a skin...
if you add thickness correctly to the 'top' it becomes a solid...
then select the new 'bottom' surface, right click > intersect with model, you will get the circle of the sink showing...
use the 'scale tool' to increase it's diameter a touch, then push/pull to the top surface creating a hole... -
As has been said... you need solids to 'subtract'.
However, the fix in this case is easier still...
Select the top and edit it.
Select the top face and use Context-menu > Intersect > with Model.
The sink now cuts a 'ring' in the top.
Select the top's face inside the sink and <delete>Done.
The sink now has a matching hole in the top...
