Ok I see what you are getting at now.
No dense supports can be generated at the bottom. Thanks for clearing that up.
I am using one support layer and it is sticking just fine.
I like simplify3d a lot but it's still not consumer grade as far as it's interface is concerned. Not in my opinion anyway.
And I go back to my other point about automatic and manual support generation being confusing and not logically arranged so far as workflow goes.
Please don't get me wrong. It's got a lot of great features. Just not happy about how you have to dig to find out how to use them.
What would be really great is if they had a little picture pop up explaining just what it is you are doing when you hover over them.
Like say inventor when you hover over revolve for example.
