Below is a list of all commands in the 2D Mesh menu:

Menu Command Description
New 2D Mesh Creates a new, empty 2D mesh.
2D Mesh Settings... Opens the 2D mesh settings which include: default z values for new nodes, options for deleting triangles etc.
Lock All Nodes Since it is possible to accidentally drag points, nodes can be "locked" to prevent them from being dragged or edited by toggling on this command.
Find Element... Selects an element given the element ID.
Find Node... Selects a node given the node ID.
Triangulate Creates triangular elements from all or selected nodes using the Delauney criteria. If triangles already exist, they will be deleted.
Renumber Renumbers mesh nodes eliminating gaps in numbering. Optionally a node string can be created and used to guide the renumbering.
Mesh → 2D Scatter Points A new 2D scatter point set is created from the 2D mesh nodes.
Mesh → TIN A new TIN is created from the 2D mesh.
Contours → Arcs Creates a new coverage containing feature arcs derived from the linear contours displayed on the 2D mesh.
Select Thin Triangles Selects triangles which meet the "thin triangle aspect ratio" specified in the 2D mesh settings.
Find Duplicate Nodes... Selects nodes that are close to each other within a user specified tolerance.
Merge Triangles Used to convert triangular elements into quadratic elements.
Split Quadrilaterals Used to convert quadrilateral elements into triangular elements.
Add Breaklines Inserts the node strings into the mesh as a new edge, creating new elements and nodes.
Convert Elements Converts linear elements to quadratic and quadratic elements to linear.
Refine Elements Subdivides elements into smaller elements.
Relax Elements... Moves mesh nodes in order to improve the quality (element shape and size) of the mesh.
Mesh → 3D Tets Creates a 3D mesh consisting of tetrahedron from the 2D mesh.
Export Exports a 2D mesh to a file (*.2dm, *.fem etc).
