Import CAD File

Using the Import CAD File automatically deactivates the analysis information of the current model.

The user can use this function even when a file is not open and can import as many CAD geometries as they wish without limits. Parasolid (Parasolid(9 to 28) (*x_t;*.xmt_txt;*.x_b;*xmt_bin) file formats and optional CAD file formats as below are supported.

Because CAD geometries do not have a length unit, the user must set the length unit when importing. The set units decide the size of the CAD geometry and both the meter and feet units are supported.

DXF 2D (Wireframe)

This function imports a DXF file created on a higher version of AutoCAD than R13. The user can import 2D surfaces as well as wireframes (a model consisting of edges).

DXF files created on AutoCAD do not have tolerance that can determine the connectivity between endpoints. Although edges may seem connected to the naked eye, they maybe intersected or not connected after import. It is recommended that the user check the edges of the AutoCAD DXF file before importing.

<When the endpoints do not coincide>

If a line is joined by multiple polylines, it may not be imported properly. It is recommended that these lines be exploded on AutoCAD before importing.

<Example of joined poly lines>

When importing a 2D DXF file, the user can simultaneously input distance from origin along x axis and y axis to move or rotate about z axis the imported file in order to place it at the desired location in the model.

Wireframes can be imported in FEA NX as a single composite line for easy management or as individual lines.

Imported intersected edges can be cut and registered using the [Break Intersected Edges] function.

DXF 3D(Wireframe)

This function imports a DXF file created on a higher version of AutoCAD than R13. It imports a 3D model on to the work space. The user can call up DXF file as a wireframe (a model consisting of edges).

DXF files created on AutoCAD do not have tolerance that can determine the connectivity between endpoints. Although edges may seem connected to the naked eye, they maybe intersected or not connected after import. It is recommended that the user check the edges of the AutoCAD DXF file before importing

When importing a 3D DXF file, the user can simultaneously input distance from origin along x axis, y axis and z axis to place the imported file at the desired location in the model.

Wireframes can be imported on to the FEA NX as a single composite for easy management, or as individual lines.

Imported intersected edges can be cut and registered using the [Break Intersected Edges] function.

Import DWG

This function imports a DWG file created on a higher version of AutoCAD than R13. It imports a CAD model onto the 2D space or 3D space.

Like the Import DXF file function, DWG files created on AutoCAD do not have tolerance that can determine the connectivity between endpoints. Although edges may seem connected to the naked eye, they maybe intersected or not connected after import. It is recommended that the user check the edges of the AutoCAD DWG file before importing

When importing a 2D DWG file, the user can simultaneously input distance from origin along x axis and y axis to move or rotate about z axis the imported file in order to place it at the desired location in the model. While when importing a 3D DWG file, the user can simultaneously input distance from origin along x axis, y axis and z axis to place the imported file at the desired location in the model.

Imported edges can be registered on the geometry set for each layer using the [Create geometry set for layers].

Import midas MxT file

Model information and loading/ boundary condition/analysis data from the 'Gen, Civil' program, other midas family programs, can be synchronized on the FEA NX. Element types, load/ boundary conditions, analysis methods not supported on the FEA NX are excluded.

The compatibility range for midas MxT files is shown below.

Import FPN file

This format links the model information file created on midas family programs (FEA, GTS NX, NFX, SoilWorks, GeoXD) to the FEA NX.

This file format also enables user to exchange information between different programs using text format.

Import Nodal Results

This function allows users to import nodal results from midas Gen and Civil into FEA NX.

Displacement results will be imported as prescribed displacement (Tx, Ty, Tz).

Reaction results will be imported as nodal loads in the opposing direction (FX, FY, FZ, RX, RY, RZ).
