5.1.7 Miscellaneous

Here is a list of all other geometry commands currently available:

Coherence;

Removes all duplicate elementary geometrical entities (e.g., points having identical coordinates). Note that Gmsh executes the Coherence command automatically after each geometrical transformation, unless Geometry.AutoCoherence is set to zero (see section Geometry options list).

Delete { Point | Line | Surface | Volume { expression-list }; … }

Deletes all elementary entities whose identification numbers are given in expression-list. If an entity is linked to another entity (for example, if a point is used as a control point of a curve), Delete has no effect (the line will have to be deleted before the point can).

Hide { Point | Line | Surface | Volume { expression-list }; … }

Hide the entities listed in expression-list, if General.VisibilityMode is set to 0 or 1.

Hide char-expression;

Hide the entity char-expression, if General.VisibilityMode is set to 0 or 1 (char-expression can for example be "*").

Show { Point | Line | Surface | Volume { expression-list }; … }

Show the entities listed in expression-list, if General.VisibilityMode is set to 0 or 1.

Show char-expression;

Show the entity char-expression, if General.VisibilityMode is set to 0 or 1 (char-expression can for example be "*").
