new to openscad. does anyone know how you would see an object you place inside another object. say you have a 4" square cube with a 2" square cube inside it. all i can see is the outer, bigger cube.

tanks in advance

Temporarily put a # in front of the outer object

tried it on this with no change. putting it wrong?

difference() {
#cube (size = [2,6,20], center=true);
translate([0,0,0]) difference(){
cube(size=[1.5,5,17.5],center=true);
translate([0,5,0])rotate([12,0,0]){
cube(size=[2,10,30],center=true);
}
}
for(i=[0:9]) {
translate([-.9,-2,-9+1.8*i]) {
rotate([45,0,0]) cube([1.8,1,2.5]);
}
}

//translate([-25,-25,-7])cube([50,50,50]);
}

Use '%' instead of '#', then it works like you want.

yes thank you. works the charm.

why is it that being able to see inner items in what i would call a ghost view not something built in? are those that know the software that good they can do it blind.

so now knowing of those two characters i did a quick look for them and came up with this one for the #

[www.openscad.org]

greg can you look at my above entry and suggest where you would put the #. i tried several places and can not get it. is it just because they do not protrude?

It would help if you specified exactly what you want to see.

Try the following code:

difference() {
	%cube (size = [2,6,20], center=true);

	translate([0,0,0])
		difference(){
			cube(size=[1.5,5,17.5],center=true);
			translate([0,5,0])
				rotate([12,0,0]){
					#cube(size=[2,10,30],center=true);
			}
		}

	for(i=[0:9]) {
		translate([-.9,-2,-9+1.8*i]) {
			rotate([45,0,0]) 
				#cube([1.8,1,2.5]);
		}
	}
}

hey bob yes your % on the first cube reference line, which is my outer box, hides it temporarily just like you said. it does this without placing # on the third and fourth cube reference lines.

this is what i get

whereas i was asking greg to help with the use of # to wind up with what is seen here

with this view i hope to physically be able to see what i am doing better to make a more intricate shape

Could it be that your OpenGL driver is not the newest version?

Sorry,but I was meaning % when I suggested #. # actually highlights the tree that follows rather than making it transparent. Another operator that is useful is * which makes things disappear alltogether. The wiki manual is quite concise and a good read.

what are the odds? 3 machines, 2 win7 n 1 mac. 3 different downloads and installs. none will give the view you get
