Diagonal inversion of two triangles

In MESH you can inverse the diagonal (edge) of a pseudo-quadrangle formed by two neighboring triangles with one common edge.

To inverse the diagonal:

1. From the Modification menu choose the Diagonal inversion item or click “Diagonal Inversion” button in the toolbar.

   

   “Diagonal Inversion” button

The following dialog box shall appear:

1. Enter IDs of nodes forming the required edge in the Edge field (the node IDs must be separated by dashes) or select this edge in the 3D viewer.

2. Click the Apply or Apply and Close button.

   

   “The selected edge”

   

   “The inverted edge”
