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"

Hey dani2442-

If you open the mesh in the editor you should find a checkbox for "Double Sided Geometry". Setting this to true will render both sides of the mesh rather than just one. I'm not familiar with Rhinoceros however I would expect a similar "2-sided" option to be available there as well.

Cheers

Doug Wilson

Does the mesh appear the same in the editor if you uncheck Double Sided Geometry? Can you check the mesh inside 3DS Max to see if it is set as 1- or 2-sided there?
