/* Todo:
- implement "dxf" mode
- implement hole cutout pattern - interference based on hole size, compatible with two sizes above and below the currently set size.
*/
// To Do:
// integrate option to choose between imperial and metric gridbeam
// integrate option to set beam width (to 1, 1.5, or 2 inch if imperial, or 25, 40 or 50 mm if metric)
// integrate option to set length (in feet or meter, depending on whether imperial or metric gridbeam ); do this
// by having the script calculate out the required segments by this method: entered length / entered beam_width = number_of_segments
// A command to draw a horizontal gridbeam with 1 inch width and 4,5 feet length gridbeam should become: xBeam imperial 1 4,5
// ------

// A segment starts from 'the middle between 2 holes + the whole itself + the next middle between 2 holes'
// Consequently, a segment equals the width of the beam (so one, one-and-a-half, or two inch with imperial gridbeam, or 25, 40 or 50 mm with metric grdbeam)

// zBeam(segments) - create a vertical gridbeam strut 'segments' long
// xBeam(segments) - create a horizontal gridbeam strut along the X axis
// yBeam(segments) - create a horizontal gridbeam strut along the Y axis
// zBolt(segments) - create a bolt 'segments' in length
// xBolt(segments)
// yBolt(segments)
// topShelf(width, depth, corners) - create a shelf suitable for use in gridbeam structures width and depth in 'segments', corners == 1 notches corners
// bottomShelf(width, depth, corners) - like topShelf, but aligns shelf to underside of beams
// backBoard(width, height, corners) - create a backing board suitable for use in gridbeam structures width and height in 'segments', corners == 1 notches corners
// frontBoard(width, height, corners) - like backBoard, but aligns board to front side of beams
// translateBeam([x, y, z]) - translate gridbeam struts or shelves in X, Y, or Z axes in units 'segments'

// To render the DXF file from the command line:
// openscad -x connector.dxf -D'mode="dxf"' connector.scad
mode = "model";
//mode = "dxf";
// To draw a bolt in the gridbeam, use the nuts_and_bolts.scad script or metric_fastners.scad script
// Use following sizes for bolts on imperial gridbeams:
// 11/32 inch bolt for 1 inch width gridbeam
// 5/16 inch bolt for 1,5 inch width gridbeam
// 3/8 inch bolt for 2 inch width gridbeam
// Use following sizes for bolts on metric gridbeams:
// 6 mm bolt for 25 mm width gridbeam
// 9 mm bolt for 40 mm width gridbeam
// 12 mm bolt for 50 mm width gridbeam
