Components penetrating through objects on insertion

[bigstick]

Apologies if this is a stupid or obvious question, but is there a plugin that will do this?

I can create cutting components, but the fairly obvious limitation is that it seems to me that cutting plane has be be flush with a surface. This means that (if I have understood everything correctly and am doing it properly) you can't create components which have a cutting plane in the middle of the geometry so that the component 'penetrates' the face.

I want to make a recessed spotlight with a bezel. I can create the component which has the recessed body of the fitting, and that will cut. I can create the bezel and glass diffuser, and that will also cut a face. However it doesn't appear to be the case that I can combine both elements and have the face cut so that the body sits behind the face, and the bezel sits in front.

The reason I'm asking in the this particular part of the forum, is because I have seen plugins which cut multiple faces for things like door and window insertion, so I'm presuming it's possible.

If I have got something wrong or have misunderstood the principles, please let me know!

No but it needs to be flush with a closed loop of coplanar edges. So simply draw a loop of those edges in your light fixture and it can work as support for the gluing plane (and cutting the hole).

Gaius, you're a Godsend! I have struggled with this for years actually, but haven't persisted because until now, I haven't really needed the facility.

Thanks a million!
