How to difference shape with text?
How do you perform a boolean difference between a shape and a block of text?
I'm trying to model an "N" cutout of a cube.
Since OpenSCAD doesn't natively support text, I'm using Write.scad
(http://www.spolearninglab.com/curriculum/lessonPlans/hacking/resources/software/3d/openscad/openscad_write.html)
to create the "N" shape. This is simply:
use <Write.scad>
write("N");
and of course adding a cube makes it:
use <Write.scad>
cube(1);
write("N");
From how I understand the difference operation, differencing these two
should be simply:
use <Write.scad>
difference{
cube(1);
write("N");
}
However, when I run this, the view pane turns black and nothing renders.
What am I doing wrong?

Try "difference()", but have a look at just the write so you know the size
and orientation of the N v's the cube.

BTW if you are using the dev snapshot see text()
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Text . It is 2D, if
you want to use it for 3D you need to linear_extrude() it.

I'm using 2014.03, not the dev version. Is this not possible with the
stable version? I am using difference(), so I'm not sure what you mean by
"try difference()". I did have a typo in my original email, I meant to
include the parens. To keep it simple, I excluded the transformations. The
full code is:
use <Write.scad>
difference() {
translate([-1, -1, -1]) {
cube(6);
}
translate([0, 0, -3]) {
scale([1.5, 1, 10]){
write("N");
}}
}
Commenting out the difference shows an N stretching out of the top of a
cube.

That works for me on 2014.03 (W7/64).

(I have the '!' as I had ther code in the editor too)
What is it doing for you?
