Zoom to each structure to inspect the SX links:▼
▲<li>The '''1d_to_2d_check_R''' file shows the cells selected by the SX boundary links. It is recommended
:*The point SX selects a single cell in which the point falls. <br>
:*The region SX selects all cells where the cell centers fall within the region.
