OpenSCAD after starting

Open one of the many examples that come with OpenSCAD (File, Examples). Or you can copy and paste this simple example into the OpenSCAD window:

Usage example 1
difference() {
    cube(30, center=true);
    sphere(20);
}
translate([0, 0, 30]) {
    cylinder(h=40, r=10);
}
OpenSCAD after pasting the example code and pressing F5

Then press F5 to get a graphical preview of what you typed (or press F6 to get a graphical view).

You get three types of movement in the preview frame:

  1. Drag with left mouse button to rotate the view. The bottom line will change the rotate values.
  2. Drag with an other mouse button (or control-drag under OSX) to translate (move) the view. The bottom line will change translate values.
  3. Use the mouse scroll to zoom in and out. Alternatively you can use the + and - keys, or right-drag with the mouse while pressing a shift key (or control-shift-drag under OSX). The Viewport line at the bottom of the window will show a change in the distance value.
