The Patch Checker toolbar contains a group of icon buttons that you can use to review quality results, sliver surfaces, elements attached to selected nodes, and so on. Click the various icon buttons to review "patches" of elements, nodes, and surfaces.

Entities placed on the user mark are used as input. The user mark is populated by using the save option from advanced entity selections, specific panels that have the save button (such as Check Elems), or via Tcl script using *marktousermark.

This tool creates "patches", or local regions, from each input entity. A patch includes only displayed entities. Patches are not created for any input entities that are not displayed. A spherical clipping is then calculated and applied for each patch, with the input entity highlighted and the adjacent entities low lighted. In order to keep the performance high, only the first 500 entities on the user mark are considered.      

The Patch Checker toolbar can be turned on and off from the View menu's Toolbars sub-menu. The detailed behavior of each button is described in the table below:
