Import: STEP

Function

This function imports a neutral geometry data in STEP (Standard for the Exchange of Product Model Data) format file. In a single project, multiple STEP files can be imported. A STEP file contains sufficient geometry data information. Therefore, it causes less problems during modeling operations.

Call

File > Import > STEP

Entity Type

Specify geometry types that will be imported.

Vertex

Import any Vertex in the importing STEP file.

As Compound

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

Curve

Import any Curve in the importing STEP 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 STEP file.
Solid

Import any Solid in the importing STEP 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.

Read All Roots (STEP Format)

If multiple Shapes exist in one Root of a STEP file, it may not be possible to import all the Shapes. In such a case, this option enables the user to import all the Shapes in all Roots. However, many duplicated shapes will also be imported. When this option is used, please check for duplicates after import.

Length-Unit

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

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

Notes

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