This tool attempts to find an optimal orientation/rotation of the object, considering three different factors:

  1. Strength: minimize the number of weak points
  2. Volume: minimize the build volume
  3. Area: minimize the surface area of the model that will require support

The tool computes a number of discrete orientations with different tradeoffs between these three factors. Each orientation is represented as an arrow and a set of bars that shows the relative values of the three factors. Click on an arrow to choose that orientation for your object.

Overhang Angle determines at what angle from vertical a portion of the model is tagged as an overhang (see the Overhangs tool for more details). 

Enter numeric values in the Factor Weights section to adjust the priority of the different factors.
