IGES
Menu: Files->Import->IGES...
With this option it is possible to import a file in IGES format (version 5.3); GiD is able to read most of the entities, which are:
Entity number and type (Notes)
100 Circular arc
102 Composite curve
104 Conic arc (ellipse, hyperbola and parabola)
106 Copious data (forms 1, 2, 12 and 63)
108 Plane (form1 bounded)
110 Line
112 Parametric spline curve
114 Parametric spline surface
116 Point
118 Ruled surface
120 Surface of revolution
122 Tabulated cylinder
123 Direction
124 Transformation matrix (form 0)
126 Rational B-spline curve
128 Rational B-spline surface
134 Node
136 Element
140 Offset surface entity
141 Bounded entity
142 Curve on a parametric surface
143 Bounded surface
144 Trimmed surface
184 Solid assembly
186 Manifold solid B-rep object
190 Plane
192 Right circular cylindrical surface
194 Right circular conical surface entity
196 Spherical surface
198 Toroidal surface
308 Subfigure definition
314 Color definition
402 Associativity instance
406 Property entity
408 Singular subfigure instance
502 Vertex
504 Edge
508 Loop
510 Face
514 Shell
The variable ImportTolerance (see Preferences ) controls the creation of new points when an IGES file is read. Points are therefore defined as unique if they lie further away than this tolerance distance from another already defined point. Curves are considered identical if they have the same points at their extremes and the "mean proportional distance" between them is smaller than the tolerance. Surfaces can also be collapsed.
Entities that are read in and transformed are not necessarily identical to the original entity. For example, surfaces may be transformed into planes, Coons or NURBS surfaces defining their contours and shape.

NASTRAN mesh
Menu: Files->Import->NASTRAN mesh...
With this option it is possible to read a file in NASTRAN format (version 68), with GiD accepting most of its entities, which are:
Entity name ( Notes)
CBAR CBEAM CROD CCABLE CBUSH CELAS1 CELAS2 CELAS3 RBAR (translated as 2 node bars)
CQUAD4 CQUADR
CHEXA
CTETRA
CPENTA
CTRIA3 CTRIAR
CONM1 CONM2 (translated as 1 node element)

CORD2C CORD2R CORD2S
GRID
There are two options that can be used when reading a mesh if GiD already contains a mesh:
- Erasing the old mesh (Erase);
- Adding the new mesh to the old one without sharing the nodes; the nodes will be duplicated although they may occupy the same position in the space (AddNotShare).

GiDML mesh
Menu: Files->Import->GiDML mesh...
With this option it is possible to read the input and output meshes stored in a .gidml file in order to visualize it within GiD.
GiDML is the input/output format (HDF5 based) for GiD Mesh Library.

- Marching cube: the well known method for isosurface extraction is applied an the result is a triangle mesh on the boundary of the body.
- Uniform Hexahedra: an uniform mesh of hexahedra fited to the boundary is generated applying a dual .
- Orthogonal Hexahedra: an orthogonal mesh of cubes is extracted from the volume selecting all the voxels withing the body bounded by the isosurface value.

- Write a log file
*****OUTPUTFILENAME filename
filename is substituted with a real file name where all the session warnings (those which appear in the GiD messages warning line) are written. This can be useful when running GiD in batch mode with the option -n (see Invoking GiD) and GiD output is desired.
- Execute a Tcl command in a batch file
*****TCL tcl_command
Note: If this command is used in a batch file and GiD is invoked with the option -n, it will not work. So that Tcl commands are executed when GiD is run without a window, you should use the -n2 option (see Invoking GiD).
- Insert comments in the code of a batch file
geometry create line 1,2
*****COMMENTS this is a comment
2,3 escape
- Print messages in the lower GiD messages line
geometry create line 1,2
*****PRINT This is a message that will appear in the messages line
2,3 escape
- Print messages in a window
geometry create line 1,2
*****PRINT1 This is a message that will appear in a new window

Menu: Files->Import->Insert GiD model...
This command lets you insert one previously created GiD model inside another one. It imports the geometry, layers, mesh and groups information. Problemtype information is neglected.
Entities from the old and the new model are not collapsed.
You can perform one Collapse operation (see Collapse) to join the old and new models.
