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

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.
