Here is the deal. I am working on a renovation project and we are filling in several exisiting shafts. These were draw as shafts and then "demo". I then fill in with a new slab. I have done this before with great results. Now when I demolish the shaft it doesn't really disapear I just can't select it anymore. I'm still really trying to get to the root of this, but has anyone experienced anything similar to this or know of any workarounds?
Thanks.
