Hi, I did hi res sculpt in Zbrush 4R4. I would like to print it in 3d printing studio. Printing studio told me that I have to resize my mesh becouse that STL is too big. They told me that in Zbrush I have to change linear value for ‘0,01 mm’ and angular value for ‘4 degrees’. I thought that they told about polygon angles and size of one polygon (or line). I can`t find it in Zbrush. Is that export option present in Zbrush or they wrong? Is there any freeware soft for do that resize conversion with setting that demanded values.
Edit: Print studio agreed for smaller polycount and lighter file (STL) without changing those values. I think this is not possible to change that values in Zbrush. I tried Meshlab but i didnt see that values there too. Solidworks can do that. I dont have solidworks so problem is gone 
but when someone will know freeware solution for my problem please free to share
