Description
The Subtraction operation allows you to subtract a domain from one or more domains. The domain which is selected last will be subtracted from the other domains.
When only two domains are selected, then the resulting object is created from the left over area of the first selected domain. When more than two domains are involved, then the marked domain will be subtracted from all other selected domains. The resulting objects all take on the same material properties of the first selected object.
