Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

I'm having the same issue. If I find anything I will get back to you. (UPDATE) Try deleting the wall you are trying to subtract from and use the box brush geometry. The issue I had was that I was using the original box that you get when you open and start a new level. It will not let you subtract from it maybe because it has other surface materials built into it already, but don't quote me on that. I used that original box to build my walls by duplicating (alt+drag). Once I deleted the wall I was trying to subtract from and added in the new box geometry in its place, it would then let me subtract from this surface. This worked for me. Hope this helped.
