For fold nodes, crossed and penetrating elements and distorted elements you can individually choose to always plot them or to only plot them if the appropriate button is pressed. This option is set by using the radio buttons and setting the option or . As the distorted and crossed element checking is very complicated it can take some time. If the delay when folding is unacceptably slow then these features can be turned off by using the option. If this is done then you will not be able to plot the distorted or crossed elements until one of the other options is chosen again. |

The colour popup allows you to choose from 15 basic colours. The cross at the bottom right of the panel (the X button) stops the entity being drawn completely. E.g. in the above figure, element distortion between 0.9 and 1.1 will not be highlighted. |
The 
For each type of entity (e.g. Foldline nodes) you can also choose the colour that the entity is drawn in (or if it drawn at all) by using the popup menus. Each popup menu brings up a selection of colours to choose.
The element thickness which is used for checking penetration can be altered by typing in a new thickness in the text box. The ranges for distorted elements can similarly be changed by typing new values in the text boxes.
Version 8.0 has some new fold options such as a new tuck fold algorithm and an element stretching option. As these options could change the way an existing origami is refolded there is an option to say if your origami will be folded using version 7.1 techniques or version 8.0 techniques. By default any new origami you define will be a version 8.0 origami and you will have access to these new functions. If you read in an old origami (version 7.1 and before) the origami version is set to be 7.1. A warning will be output when you first select the origami to say that you are using an old origami. The reason a warning is given is to bring to your attention that if you change the origami to be version 8.0 the folds may change. If you have a previously correlated airbag then leave the version at 7.1 and the folds will not be changed. You will not be able to use the new functions until the origami is changed to be version 8.0.

The final button on the panel is used to try to stop stretching of elements during folding. This only applies to thin folds. By default elements will be stretched as the centre plane of the elements which are being folded is placed at the fold point. Elements on one side of the plane will get smaller, elements on the other side of the plane will get larger. |

If the button is pressed then the folder will attempt to stop any elements from stretching. To do this the fold point has to be moved slightly. For folds which are less than 180 this can generally be done. If the fold is a 180 fold then if you try to fold multiple layers which are thick a point is reached when the fold cannot be done without stretching any elements. If the thickness is less than this then the stretching will be eliminated. If the thickness is more than this then the stretching will be reduced as much as possible. |
