# Analysis

**Show Analog Model** - Display the truss's Analog Model generated for the analysis checks.

**Show Analog Panels** - Toggle whether analog panels are shown on top of the analog model.

**Display Forces Options** - Choose from a list of forces to display on the component for a specific load case. Choose a specific load case first from the list of load cases in the panel. See [Display Forces Options](/design/reference/display-forces.md) for a full description of the visuals each option enables.

**Show Loads** - Toggle the visibility of loads for the selected load case.

* There are distinct visuals for distributed and point loads
* The length of the arrow is scaled according to the relative magnitude of the load
* The direction of the arrow indicates the direction of the load
* The tip of the arrow is located near where each load is applied
  * If multiple loads are applied at the same location, their visuals are stacked on top of one another instead of overlaying them

**Boundary condition**: A boundary condition describes how an analog joint transfers force or moment with an external connection. Most commonly, the external connection is a bearing support.

**Unrestrained**: An analog joint that is not considered subject to external reactions.

**Restrained**: An analog joint that transfers either force or moment between the truss and external connections.

**Pinned:** A restrained joint that transfers force in all directions.

**Horizontal Roller:** A restrained joint that transfers force vertically, but not horizontally.

**Vertical Roller**: A restrained joint that transfers force horizontally, but not vertically.

**Fixed**: A restrained joint that transfers moment and force in all directions.
