CST-MWS Separating shapes after adding them and saving

I designed a dipole meander coil and added all my shapes together then saved and simulated several times.
Now however, I would like to change the geometry of my meander, but I cannot do that after adding the shapes!
Is there a way of undoing a Boolean addition or separating shapes? I have tried right-click then separate, but it doesn't do anything
please help!
Thank you

you can bring xyz axis and cut them apart or try undo..

Same problem
Did you find a solution?

If the problem is just to undo the Boolean operation?
Here is one possible solution which can help but all depends on the complexity of problem
so
Go to the History Tree which is available in CST
Find the command which you want to undo in this case it will be Boolean function
Delete the command from History list
Update the model
and I hope it will solve the issue for simple geometries you can try
I find History Tree a very powerful tool in CST it adds lot of flexibility for working
Let me know if it works for you
