Is there a better way?
Hi:
I'm trying to do what seems to be a simple thing - create a ruler with
Openscad.
Originally intended to help me size things in the display window, but now
converted to creating a physical ruler. Although I've used it for display
purposes before (really slow), this is the first time I've tried a render.
It is not rendering - or, it sat at 595/1000 for hours, and I left it
overnight. This morning, OpenSCAD was not running. Of course, I'm not
sure if the machine rebooted overnight.
Any suggestions?
Thanks for your help!
//make a ruler of sorts
module ruler(end)
{
for(i=[0:10:end-1])
{
color("Black")translate([i,0,0])cube([.2,4,.04]);
color("Black")linear_extrude(.02)translate([i,4,0])text(str(i),size =
2);
}
for (j=[1:end])
{
color("DeepSkyBlue")translate([j,0,0,])cube([.1,3,.03]);
color ("SpringGreen")translate([j-.5,0,0])cube([.1,2,.03]);
}
}
color("pink")
cube ([150,12,1]);
translate([0,0,1])ruler(150);
translate([150,12,1])
rotate([0,0,180])
ruler(150);

I don't think you meant to nest the two loops.
This is faster:
module ruler(end){
for(j=[1:end]) {
color("DeepSkyBlue")translate([j,0,0,])cube([.1,3,.03]);
color ("SpringGreen")translate([j-.5,0,0])cube([.1,2,.03]);
}
for(i=[0:10:end]){
color("Black")translate([i,0,0])cube([.2,4,.04]);
color("Black")linear_extrude(.02)translate([i,4,0])text(str(i),size
= 2);
}
}
Also rather than unioning 3D objects, union them as 2D squares and then
linear_extrude the result is much faster.
I also moved the lines to centre them to avoid non-manifold problems where
they overlap. It renders in 1 minute 40 on my machine.
module ruler(end){
color("DeepSkyBlue")
linear_extrude(0.03)
for(j=[1:end])
translate([j-0.05,0,])square([.1,3]);
color ("SpringGreen")
linear_extrude(0.03)
for(j=[1:end])
translate([j-.55,0,0])square([.1,2]);
color("Black") {
linear_extrude(0.04)
for(i=[0:10:end])
translate([i - 0.1,0])square([.2,4]);
linear_extrude(.02)
for(i=[0:10:end])
translate([i,4,0])text(str(i),size = 2);
}
}

Thank you both.
This is definitely a learning experience - and the most direct way isn't
necessarily the best!
