Example I am going to use an earring in my example and what I am trying to achieve. I wish to have a circle say 3mm wide and inside this circle I wish to place a two digit number. I place my number lets say 24 so that it slightly lapses my circle. I want the circle and the number to remain cut away the rest leaving a ring shape with a number inside. I assume that I need to weld the two layers into one , however when I do this one of the numbers disappears. That’s my 1st issue. The 2nd how do tell the software what to keep and what to cut away. Have searched and cant seem to find an instruction of what I want , any help here most welcome. Must add that I am new to LB so there’s a good chance I am missing the obvious.
You probably want cut shapes, but a visual example of what you are trying to do would be helpful.
Select the number, then shift select the circle. Open Boolean Assistant (CTRL+B)and you can preview what each option does before committing.

I want to cut away everything but the circle and number a kind of skeleton. I am thinking that the circle band may need to be wider to incorporate the mounting hole.
Separate the 2 and the 4 into different objects. Weld one at a time to the inner ring.
I guess that you want the 2 and 4 and the ring to be solid?
I like to work in the FILL mode, so I can better see my expected results.
Thanks for the advice I am getting the same effect as soon as I hit weld the object I am trying to weld disappears even using your suggestion one number at a time Hmm. ??
Use Boolean tools. Ctrl+B
You can preview what tool has which effect. I am afk right now, but can drop back by when I am online with my desktop. Try it and see if you can get it worked out using CTRL+B tool.
The top left corner of the 4 is touching the outside of the ring. That can cause problems.
Weld the 2 and the 4 together first before the boollean command. Here is my example just a different font.
If the rings are not grouped it shouldn’t be a problem. Just select the inside ring.

Ok have progressed by creating the number separately I can weld them together but it still wont weld to the outer ring, also cant get it into a state the allows me to open boolean assistant
As @JimNM said just select the inner ring:
This is one of the problems If I select the inner ring it also selects the numbers , and in this state boolean is ghosted. should I select the whole thing then boolean becomes available, selecting union a-b removes the numbers one again but leaves the shape in the circle where the text once was . ??
First and foremost Make sure everything is ungrouped. Select the numbers only and click weld.
Select the welded numbers and the inner ring only.
Open Boolean Assistant and chose the correct subtract(it depends on the selection order as to which one is correct)A-B or B-A.

You have to select text and inner circle with CTRL.
Select both and make sure they are Ungrouped…
Is it correct that a Boolean operation can only be applied to two objects or two groups of objects?
As a learner myself, I am far from giving advice to others, but this is how it worked for me:
- mark the outer circle
- shift-mark the inner circle
- ctrl B → A minus B
- mark the “2”; shift mark the “4”
(i drawed them separatetly to overlap them) - ctrl B → “Union”
- Shift Mark the ring
- ctrl B → “Union”
- Shift mark the little circle
- ctrl B Operation “Union”

Abreviations wellcome!
That is correct. The only exception that I’m aware of is the weld command. You can select multiple items and use weld. Union, which is very similar to weld can only be used with 2 objects or groups.

Ok followed your instruction and they are now welded , thanks for spending the time to work through this with me.
