FYI I tried the Tire Fixed file from above in thí topic and I get the same warning

Hello I am having a similar problem it seems. I keep getting a warning saying "Not Enough Input"

I have grouped everything according to requirements and left everything on Layer0

I am using Sketchup pro 16 = flowify 1.1 on a windows 10 Computer

I hope I can get some help here Flowify seems like a great prugin.

Thanks

Kevin
