Some criteria are applicable to all <b>Entity types</b>:
<ul><li>
<b>Belong to Geom</b> selects entities whose all nodes belong to a
submesh on the shape defined by <b>Threshold Value</b>. The threshold shape
must be sub-shape of the main shape of mesh.
<b>Belong to Geom</b> selects entities whose all nodes
lays on the shape defined by <b>Threshold Value</b>.
The threshold shape can be sub-shape of the main shape of mesh, in
this case the algorithm works fast, and it also can be any other
shape, but in this case the algorithm works slower.
</li><li>
<b>Lying on Geom</b> selects entities whose at least one node belongs to a
submesh on the shape defined by <b>Threshold Value</b>. The threshold shape
