I am trying to subtract with upward extension a composite wall type (target) using a roof as an operator. The subtract only cuts some of the elements within the composite, leaving the outside element extending above the roof? Never seen anything like that before. The other composite wall types worked fine, but they don't have as many layers/materials. Has anyone seen this before?
By high lighting the wall you can see the thickness below the roof has more layers than above. Here there are about 2 inside layers that are extending above the roof. earlier it was only the one outside layer that extended above the roof. ????!!! My solution was to create a separate wall at the roof bearing line of the thinner material used else where and only extend the thicker material to that brg line. This solution actually reflects the true conditions on the interior anyway.
