GiD_Info layers

This command returns a list of the layers in the project.These options are also available:

  • <layer_name>: If a layer name is given, the command returns the properties of that layer.
  • -on: Returns a list of the visible layers.
  • -off: Returns a list of the hidden layers.
  • -hasbacklayers: Returns 1 if the project has entities inside back layers.
  • Note: GiD_Info back_layers returns a list with the back layers


in: GiD_Info back_layers

out: Layer2_*back*

  • -bbox ?-use geometry|mesh? <layer_name_1> <layer_name_2> ...

Returns an item with a list of six real numbers representiong two coordinates (x1,y1,z1,x2,y2,z2) which define the bounding box of the entities that belong to the list of layers.

If the option -use geometry|mesh is used, the command returns the bounding box of the geometry or the bounding box of the mesh.

If the list of layers is empty, the maximum bounding box is returned.

  • ?-count? -entities <type> ?-elementtype <elementtype>? ?-higherentity <num>?: One of the following arguments must be given for <type>: nodes, elements, points, lines, surfaces or volumes. A layer name must also be given. The command will return the nodes, elements, points, lines surfaces or volumes of that layer. If -count is set then the amound of entities is returned instead of the list of its ids.

For elements it is possible to specify -elementtype <elementtype>to get only this kind of elements.

-higherentity <num>Allow to get only entities with this amount of higherentities.

  • -canbedeleted <layer_name> returns a list with two items: a boolean 0|1 to know if layer or its child layers have some entity or parts in back layer or conditions over the layer. the second item is a message explaining the cause to not delete it directly.
