scadbuild

This allows scad files to be built in batch which will produce a preview .PNG and optionally a .OBJ and .STL output for each.

Tip Make sure the development version of Open Scad is installed as it has needed options for exporting.

Tip If first time set the source and destination directories.

Building

The build is a single project that should build a 64 bit version and executable.

Example Scad File "lib_rotor.scad"

// measure in mm and scale final results

use <utility.scad>  

module lib_rotor
(
    blades = 3,
    rad = 20, 
    base_h = 6,  
    bl_l = 60, 
    bl_w = 10, 
    bl_angle = 15, 
    blade_segs = 9, 
    detail = 1, 
    cap = 1
)
{
    csegs = blades < 3 ? 8 : blades;
    crot =  360.0 / (blade_segs * detail) * .5;

    // Draw a single rotor blade
    module draw_blade()
    {
      rotate([bl_angle, 0,0]) 
      translate([bl_l  ,0,0])  
      scale([bl_l, bl_w, 1])   
      linear_extrude(height = 2, center = true)  
      rotate([0,0,crot]) 
      circle(1, $fn = blade_segs * detail);
    }
        
    // draw cap on top if wanted   
    if (cap == 1)
    {
        sphere(r = rad * .5, $fn = 8 * detail);
    }

    // Draw the base
    chamfer(r = rad * 0.25, $fn = 6 * detail)
    {
        cylinder(h = base_h, r = rad, $fn = csegs);
    }

    // Draw each blade around the base
    st = 360.0 / blades;

    for (i = [0:st:360])
    {
        rotate([0,0, i]) draw_blade();
    }
}

// Outputs sample usage ... this is the preview and default .STL .OBJ

mm2m()
{
    translate([0, 0, 0]) lib_rotor();
    translate([300, 0, 0]) lib_rotor(blades = 5, base_h = 4);
    translate([600, 0, 0]) lib_rotor(blades = 2, base_h = 4, rad = 15, blade_segs = 6);
};
