/* This is a first pass at dimension lines for OpenSCAD. The text generated for
* this comes from http://www.thingiverse.com/thing:59817, and I gratefully
* acknowledge user PGreenland for creating this dotmatrix style font.
*
* Download his file first, TextGenerator.scad, before attempting to run this
* program.
*
* What this program does:
*
* This program can draw lines with arrows and has a primitive dimensioning
* element for putting text within arrows. In addition, should the area being
* dimensioned be too narrow, there is a provision for putting the text on
* either side of the arrows.
*
* The dimension lines are drawn on the xy plane and are meant to be seen in a
* top view.
*
* =======================================================
* Be sure to view this from above -- ctrl-4
* =======================================================
*
* Available:
*
* Assorted constants to ease the use of dimensioning line. Because there is
* no introspection regarding the dimensions of your creations, you will want
* to adjust the parameters to fit the context of your creation. You can adjust
* the size of the text, lines, etc to match the rest of your objects.
*
* the following functions or modules are available.
*
* line(length, width, height=DIM_HEIGHT, left_arrow=false, right_arrow=false)
* Can draw a line with the options of including an arrow at either end
*
* circle_center(radius, size, line_width)
* Draws the cross in the center of a circle. There are defaults for the
* cross size and line width
*
* dimensions(length, line_width, loc=DIM_CENTER)
* draws text within lines, such as <--- 3.5 --->
* with the use of the variable loc you can alter the placement of the text
* loc=DIM_CENTER <--- 3.5 ---> this is the default
* loc=DIM_LEFT 3.5 <---->
* loc=DIM_RIGHT <----> 3.5
* loc=DIM_OUTSIDE ---> 3.5 <---
*
* leader_line(angle, radius, angle_length, horz_line_length,
* direction=DIM_RIGHT, line_width, text)
*
* for use in pointing to the edge of a circle and showing text
*
* usage of the leader line:
* translate to the center of the circle
* Typically leader lines have a bend in them. The angle variable is used
* to specify the angle from which the line will point to the center of the
* circle. The radius specifies the location of the arrow. The
* angle_length is distance that the leader line takes until meeting the
* horizontal line. Once the angled line meets the horizontal line, that
* line will either extend to the right or left. direction and therefore
* be either DIM_RIGHT or DIM_LEFT. line_width typically would be whatever
* constant you have selected for all your dimensioned lines. Finally, the
* text will be the value that you wish to show, such as R 0.500.
