// ---------- NOTES FOR A PROPER RENDERING IN OPENSCAD -----------
// First of all, make sure you are using the latest version of OpenScad (>= 2014.05.31)
// Then, it is important to change a default setting. Go to: Edit --> Preferences --> Advanced
// And increase "Turn off rendering at 2000 elements" to a larger number like 20000
//
// If problems persist, you may need to install the MCAD (<http://reprap.org/wiki/MCAD>)
// and Obiscad (<https://github.com/Obijuan/obiscad>) libraries into the /libs directory.
// With Git, this can be achieved automatically by running the following command:
// git submodule update --init
// -------------------------------------------------------------
// NOTE: For a proper rendering in OpenScad it is important to change a default setting:
// Go to: Edit --> Preferences --> Advanced
// And increase "Turn off rendering at 2000 elements" to a larger number like 20000
// ---------- GENERATING THE STL FILES ------------------------
// In OpenScad, it is possible to preview designs (F5 key) or to render them (F6 key)
// to be able to export them as STL files ready for 3D printing.
// Please note that some parts will only be present in the preview, but not in the
// final render. This is normal, as they are used only as a reference and do not need
// to be 3D printed.
//
// The main file that needs to be opened with OpenScad is Cyclone.scad (this document).
// From here, it is possible to select most of the parts, using the root modifier (!).
// Place it before a function to exclusively render that subtree. When used, for instance, as
// !Cyclone_Y_frontFrame();
// it will show only the frontal Y axis frame. Rendering it with F6 will output only
// that part, which will be ready to be exported as STL.
//
// It is also possible to generate larger STL files that contain multiple elements,
// and afterwards split them. This can be achieved with a software like Cura, that
// also allows easy rotation and positioning of the models for printing.
// To split STLs in Cura: right click over the part --> "split into parts"
// -------------------------------------------------------------
