//OpenSCAD library modules - written from scratch -

// (c) Pierre ROUZEAU(aka PRZ)2015-2021 Licence: LGPL V3
|
|
// Rev. 7 may 2017 : corrected ldupln function, which was making wrong count, so wrong tenons/slots
|
|
// Rev 2021: Add profiles, misc. modifications, add 'dark' color.
|

/*OpenSCAD primitives gives a priority to z axis, which needs a lot of subsequent rotations. So, you quickly find yourself lost between your axis, which have been swapped by the rotations. That drive for complex objects to build them on a X/Y plane, then to rotate the ensemble. It is tedious and unpractical.
|
|
Also, OpenSCAD is using a lot of brackets, which are hard to get on some non-QWERTY keyboards.
|
|
This library is aimed to ease openSCAD programming and improve readability. Also, primitive names are short. This is not the todays trend, but I find it useful, whithout real penalty.
|
|
So in the proposed library:
|
|
a) Nearly all primitives could be used for all three axis. This is simply done by having the axis name being the last letter of the primitive (primx, primy, primz...).
|
|
b) The translation parameters are part of most primitive (not all)
|
|
c) You could use negative extrusion and where physically sound, negative dimensions.
|
|
d) Setting the main dimension parameter negative will center the extrusion, saving the 'CENTER' parameter - for dimensions which could not be physically negative (a diameter...)
|
|
e) No vector use, so no brackets
|
|
With that, you have the primitive and associated movements done in one go. Designed for my own purpose, I find that useful and a wrist saver.

//=== Tenon and mortise/slots library, for laser/router cut

// Beware of the axis name. The first axis is the direction of propagation of the slots/tenon
|
|
// The second axis name is the second plane axis, slot plate wise. This is done to have the same name for the connecting modules, hence, the slotxy will be in an horizontal plate, with propagation in x, while the connecting tenonxy will be for a vertical plate, oriented on x
|
|
// library is yet limited to xy and zx combos. Use rotations for other axis
|
|
// As the slots are holes, the slot module is not only a primive but also an operator, so it COULD be used to MODIFY your plate objects. The location coordinates are the last two parameters (x,y or x,z). Typical use will be slotxy(slotlength, interval, tlength, thktenonplate,x,y) myplate(); Alternatively, if not used as an operator, it just creates the holes.
|
|
//You shall define the 'cutplay' and 'bithole' parameters (look configuration file) to take into account the width of the laser cut or diameter of the bit. The global holeplay variable will so be set to a negative value equalling the laset beam cut diameter (approx 0.2mm diameter), while doing the exportation to dxf files. Such play make the slots invisibles in your model (the slots are smaller than the tenons), if you are not defining a protrusion.
|
|
// So, during the development of your model, a positive value for holeplay shall be defined (1~2). Note that the visible play is double in length than in width. This is normal, as the plate thickness will not be affected by the cut.
|
|
//Neither the slot nor the tenon are centered. Negative thicknesses or negative length could be used, but with caution.
|
