Import: IGES

Function

This function imports a neutral geometry data in IGES (Initial Graphics Exchange Specification) format file. In a single project, multiple IGES files can be imported. IGES files do not contain sufficient geometry data information. Therefore, they cause more problems during modeling operation. Therefore, STEP format data file is recommended.

Call

File > Import > IGES

Entity Type

Specify geometry types that will be imported.

Points

Import any Vertex in the importing IGES file.

As Compound

When a number of Points are imported, it is recommended to make them as a single compound for easier management and operation.

Curve

Import any Curve in the importing IGES file.

As Compound

When a number of Curves are imported, it is recommended to make them as a single compound for easier management and operation.

Surface

Import any Surface in the importing IGES file.
Solid

Import any Solid in the importing IGES file.

Option

Modify importing Shapes using the following options.

Sew

Create a Shell from importing Surfaces. Sew Tolerance must be entered.
Optimize Tolerance

A tolerance of imported geometric Shape often becomes improper during importing operation. Therefore, it is recommended to turn this option on to perform the tolerance optimization for all imported Shapes.
Simplify B-Spline to Analytical Type

This option changes B-Spline Shapes into canonical shapes such as Cylinder and Plane for faster and accurate computation during modeling.
Length-Unit

Select the unit system which will be applied to imported Shapes.

Define advanced options for Importing operation. It is strongly recommended to keep the default value.
 

Notes

Optimize Tolerance, Recognize Canonical Type, and B-Spline Continuity can significantly improve imported Shapes. However, for a large scale or complex model, it may cause a very long computational time.
