# It is possible to constrain GHS3D with another mesh or group.
# The constraint can refer to the nodes, edges or faces.
-# This feature is available only on meshes without geometry.
+# This feature is available only on 2D meshes without geometry.
# The constraining elements are called enforced elements for the mesh.
# They can be recovered using groups if necessary.
-# In the following examples, a box and a cylinder are meshed.
+# In the following examples, a box and a cylinder are meshed in 2D.
# The mesh of the cylinder will be used as a constraint for the
# 3D mesh of the box.
