Connect 3d curves? Removal of material?

[CJB_JHB]

I'm sorry to be asking for basic help but I seem to be having a hard time.

Edit: 3d curve is referred to as wireframe in other cad programs?

I am attempting to make a body with space hollowed out inside.

I've created a circle and pulled it a distance through the body which hollowed out an area.

I then moved the work plane down and created the internal shapes I need... Except now the material is not being removed from the outer body (no internal space created).

How do I remove material from a body using 3d curves?

Also how to I attach 3d curves to each other.
Arrows in my image are pointing to where there is a disconnect between features.
I've also attached my wip so feel free to get me going in the right direction.

Thanks for the help.

Truly appreciated.

Thank you!

Simpler than I expected.

Now I'm having to make a feature that I can't figure out how to create.
Can I make this feature with circles?

Hello Charles

you could again remove with angular pull.

Create a new workplane on axis of the inner form.

Then get the existing elements like in te following picture.

With the Probe Selection it is possible to catch elements inside of a part.

Push the button, klick on the part where is the element what you want to get.

A table comes up and wen you go slowly with the cuser over them, the elements will by highligted.

Then switch of the part, draw geometry a and remove material with angular pull arround axis b.
