I was after some help, i am trying to print wheels and tyres, the issue i have is Cura will only import STL files which changes a radius into a segmented arch. How do i get around this so i get a nice clean circle

    It's not cura doing this.  The curves are in the STL file.  Your CAD software is doing that when it converts to STL.  What software are you using?  Most of them have options where you can set resolution for the STL.  Don't go overboard.  Probably 1mm is good enough.  If you get too many triangles in the STL you can have millions of triangles for a simple shape (like a cylinder).  Also it can be a problem printing - the printer can only buffer 16 moves so it might slow down to a crawl if you have too many triangles in the STL.

    Hi GR5 thanks for your help, we have sorted it out with your directions and will try the print tonight, FYI we are using Top solids for wood to do our cads
