 Scan&Solve Pro has the ability to analyze wood and other orthotropic materials where the mechanical properties of the material vary depending on orientation. The material orientation for wood is defined by the long grain direction and the radial growth direction. These directions are described by a coordinate system with axis 1 (red) aligned along the grain, axis 2 (green) tangential to the growth rings, and axis 3 (blue) perpendicular to the growth rings. To view, toggle the display of the material coordinate systems from the [[wiki:sns:snspro:controls#Settings Tab|Settings Tab]]. Scan&Solve Pro has the ability to analyze wood and other orthotropic materials where the mechanical properties of the material vary depending on orientation.

-**Important Note:**The material coordinate system convention used by Scan&Solve is different from that used by the wood industry where axis 2 is usually the radial direction and axis 3 is tangential to the growth rings. The Scan&Solve convention is derived from the system commonly used for composites, with the wood's growth direction analogous to the composite build direction (axis 3). Mechanical properties defined in one convention are related mathematically to those in the other, so conversion between the two is possible.+**Important Note:** The material coordinate system convention used by Scan&Solve is different from that used by the wood industry where axis 2 is usually the radial direction and axis 3 is tangential to the growth rings.

 The [Rift Sawn] and [Flat Sawn] options use the principal volume moments of inertia of each component to identify the directions for axis 1, 2, and 3 of the wood coordinate system. When the principal moments are indistinct, the user is prompted to select the origin and axis directions manually. The [Specify] and [Guide] options allow arbitrary grain orientations to be specified by choosing points or geometry to guide the coordinate system creation. Use of each of these options is described below. The [Rift Sawn] and [Flat Sawn] options use the principal volume moments of inertia of each component to identify the directions for axis 1, 2, and 3 of the wood coordinate system.

 Use the [Rift] button to point the wood grain (axis 1) along the component's "long" direction and the wood's tangential direction (axis 2) with the component's "short" direction. The wood's radial direction (axis 3) is then computed to produce a right-handed coordinate system. If the component's principal moments are indistinct, Scan&Solve will prompt to specify the wood coordinate system manually. Use the [Rift] button to point the wood grain (axis 1) along the component's "long" direction and the wood's tangential direction (axis 2) with the component's "short" direction.
