The Cylinder() primitive command will add a cylinder or tapered cylinder to your model.
In it’s basic form like the cube() and sphere(), the cylinder() command does not need any parameters.
cylinder();You can create a cube with the unit measure of 1 by adding the above command, here is the result:
SO while that does not look like a cylinder, according to OpenSCAD it is a cylinder. OpenSCAD forms cylinders using faces. If you would like a smoother looking cylinder you can increase the resulting number of faces by changing the $fn variable.
$fn=25;The $fn variable, fragment number, with a value of 25 will result in the following object. You can add the $fn before or after the object.
The cylinder in it’s basic form can receive a height and radius.
cylinder(h=5,r=4);
In it’s final form we can create cones and truncated cones. By providing two radii, r1 and r2.
cylinder( h=8,r1=5,r2=1);
Nice small doc, but I don’t found the function for made a fine surface.
To make the surfaces of the cylinder more “fine” you can either begin the script with the fn$ variable.
To apply a number of facets ( i think that is what fn stands for, i forget now ) to all objects, place the $fn variable at top of code.
$fn=50;
or to specify the number of facets for an indivual object include it in the object defination:
cylinder(h=5,r=4, $fn=50);
“You can create a cube” think there’s a typo here. should read “cylinder”.
