openscad

hey all,

ive downloaded openscad for windows and seem to have an interesting problem with it. when i do the example with the difference from the wikipedia manuel, it only renders two cylinders of different colors, rather than cutting one away. here is the code from the example

union() {
cylinder (h = 4, r=1, center = true, $fn=100);
rotate ([90,0,0]) cylinder (h = 4, r=0.9, center = true, $fn=100);
}
difference() {
cylinder (h = 4, r=1, center = true, $fn=100);
rotate ([90,0,0]) cylinder (h = 4, r=0.9, center = true, $fn=100);
}

any ideas? thanks

Did you do a full compile and Render - you pressed F6 or Menu /design / compile an render
or a compile - you pressed F5 or Menu /design /compile?

Note

a compile is good to see what is going on and is quick but uses a green area to show removed section
a render is slow but shows you the final product.

You have BOTH the example code for UNION and DIFFERENCE together.
Use only ONE or the other...

Start OpenSCAD, add the following CODE to the editor and press F6.

difference() { 
cylinder (h = 4, r=1, center = true, $fn=100); 
rotate ([90,0,0]) cylinder (h = 4, r=0.9, center = true, $fn=100); 
}

This shows DIFFERENCE!

Now clear the CODE, add the following CODE and press F6.

union() {
cylinder (h = 4, r=1, center = true, $fn=100);
rotate ([90,0,0]) cylinder (h = 4, r=0.9, center = true, $fn=100);
}

This shows UNION.
