Modifications to imported files (without operation tree) are completely natural and result from the widespread exchange of data.
However, the available operations do not always work and you have to use different methods. Walls cannot be removed, regardless of the method and number selected.
You can cut out the problem area with a regular solid operation.
Next moving the wall we fill the break.
Again I'm removing the wall – teraz jest to już możliwe.
Ready.
