CAD model export settings

CAD model export settings

Settings related to exporting various types of models through the Export CAD dialog box are listed below. FEM export settings are also described. All of the tabs and settings are not available for all export types. The export types are listed next to the settings, so that you can see which export type the setting belongs to. The Export CAD dialog box opens when you click File menu > Export > CAD .

Conversion tab

Option

Description

Export type

Profile conversion file

Material conversion file

Twin profile conversion file

Set the conversion files you want to use.

Conversion files map Tekla Structures profile and material names with names used in other software.

All

Parameters tab

Option

Description

Export type

Output file

The file name of the exported file. You can also browse for the file.

All

Type

Select the export format.

All

Origin X, Y, Z

Set the origin coordinates to place the exported model in a specific location.

PML , SDNF , XML

Split members

Splits a part in the Tekla Structures model into several elements in the STAAD or DSTV model.

FEM

Combine segmented members (MicroSAS)

Gives you the option to combine multiple parts to form one part in the exported model.

For example, if you have divided a beam into several elements and select the Yes option, Tekla Structures combines the elements so that they form one beam in the exported model. With the option No every element of the beam in the model forms individual beams.

FEM (MicroSAS)

PML tab

Option

Description

Export type

Units (for PML only)

Select the units for the export model.

PML

Export cut parts

Controls whether cuts are included in the export. Yes exports part cuts.

When you use PML, enter the Tekla Structures profile names in the conversion file. This makes the other software consider parts as beams and columns, not as plates, and reduces the export file size.

PML

SDNF tab

Option

Description

Export type

SDNF version number

Select the SDNF version to be used in the export.

With StruCAD, use SDNF version 2.0.

SDNF

SDNF(PDMS)

PDMS

Apply cuts and fittings

Select Yes (default) applies cuts and fittings in the export.

SDNF

SDNF(PDMS)

PDMS

Position number type

The SDNF file contains identifiers, which can be included in a part’s user-defined attributes, or as position numbers. You have the following options:

  • Part position

    The identifier becomes the part’s position number. Do not use the Part Pos_No fields with this option.

  • Assembly position

    The identifier becomes the assembly’s position number.

  • Universal ID

    The identifier becomes a user-defined attribute for the part.

To make user-defined attributes visible, you need to add them to the objects.inp file.

SDNF

SDNF(PDMS)

PDMS

Consider offsets

To ignore the offset records during export, select No , and to take them into account, select Yes.

This setting does not affect the actual start and end point information, only the offset. Tekla Structures writes the start and end points based on the actual solid object, not on the reference line.

SDNF

SDNF(PDMS)

PDMS

PDMS phase offset

PDMS phase offset defines phase offset for exported parts. For example, if the first phase in Tekla Structures model is 1 and you enter 10 for phase offset, Tekla Structures parts in another software get the phase from 11 and up.

SDNF

SDNF(PDMS)

PDMS

Engineering firm

Enter the name of the engineering company.

SDNF

SDNF(PDMS)

PDMS

Client

Enter the name of the client.

SDNF

SDNF(PDMS)

PDMS

Structure ID

Enter a unique identification number for the exported model.

SDNF

SDNF(PDMS)

PDMS

Project ID

Enter a unique identification number for the exported project.

SDNF

SDNF(PDMS)

PDMS

Revision number

Enter an optional revision number. Tekla Structures takes the revision number from the user-defined attributes (REVISION_NUMBER) of the model. If this field is blank, Tekla Structures uses a revision number from the CAD export dialog box ( Revision Number ).

SDNF

SDNF(PDMS)

PDMS

Issue code

Tekla Structures writes an issue code in the header section of the output file. For PDMS, this value should always be " Tekla Structures ".

SDNF

SDNF(PDMS)

PDMS

Design code

Define the design code to be used in structural design.

SDNF

SDNF(PDMS)

PDMS

XML tab

Option

Description

Export type

Units

Specify unit conversions (MM, M, IN, FT). For example, for a Tekla Structures model created using millimeters, select IN to convert all part dimensions to inches in the output file.

XML

XML structure ID

Unique identification number for the exported model. You must always enter the identification ID. Tekla Structures uses this value to identify the model if you re-export it.

XML

XML structure name

Unique name of the exported model.

XML

Staad tab

Option

Description

Export type

Profile table

Select the profile type.

FEM (STAAD)

Parametric shapes when possible

Use to define how Tekla Structures exports the profiles PL, P, D, PD, SPD to Staad.

Yes exports the profiles as parametric shapes so that STAAD can identify them correctly.

No exports all profiles as standard STAAD shapes.

FEM (STAAD)

DSTV tab

Option

Description

Export type

Version

Select the DSTV version to export.

FEM (DSTV)

Element reference with

Select CROSS-SECTION to export a static model or MEMBER_LOCATION to export a CAD model.

FEM (DSTV)
