CAD model import settings

CAD model import settings

The settings related to importing various types of models through the Import Model dialog box are listed below. All of the tabs and settings are not available for all import types. The import types are listed next to the settings, so that you can see which import type the settings belong to. The Import Model dialog box is displayed when you click Properties in the Import Models or New Import Model dialog box.

Conversion tab

Option

Description

Import 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.

For SteelFab/SCIA, these options are located on the Parameters tab.

Action when object status is (compared to)

Previous plan lists the objects in your model, compared with the objects in the file to be imported. They can be New , Modified , Deleted , or Same.

Tekla Structures compares the state of imported objects with those in your model. They can be Not in model , Different , or Same.

Use the options under Not in model , Different , and Same to specify the actions when importing changed objects. The options are No action , Copy , Modify , or Delete.

CIS Model/CIMSteel

CIS version

Select CIS/1 or CIS/2 :

  • CIS/1 imports files compatible with the CIMsteel LPM4DEP1 schema declaration.

  • CIS/2 imports files compatible with the CIMsteel CIS/2 (STRUCTURAL_FRAME_SCHEMA) schema declaration.

CIS Model/CIMSteel

Default yield stress limit

Default material when yield stress > = limit

Default material when yield stress < limit

The Default material when yield stress < limit setting is used for SACS import file. Define the material to use if yield stress is less than the limit.

The setting Default material when yield stress >= limit is used for SACS or DSTV import files. For SACS, this field defines the material to use if yield stress is greater than or equal to the limit. For DSTV you can enter the material grade here, if it is not included in the import file.

FEM

Combine members

Max length for combining

To combine several elements in the FEM or CIS model into one part in Tekla Structures , set Combine members to Yes.

For example, if a beam in a file consist of more than one element, and you select Yes , the elements are combined to form one beam in the Tekla Structures model.

If you use the value No , Tekla Structures creates a beam for each element in the FEM or CIS model.

Max length for combining is only applied if you set Combine members to Yes. Use this setting to define the maximum length for combining parts. Tekla Structures combines elements into one part only if their combined length is less than the value you enter here.

FEM

CIS Model/CIMSteel

Ignore offsets

CIS/1 and CIS/2 analysis models can include member offsets, which means that nodes are not exactly at the beam’s end points. With the default Yes , Tekla Structures uses these offsets to locate the physical members. With No , Tekla Structures determines the location using the node locations.

CIS/CIMSteel

Ignore forces

Use to define how forces are imported. With No , Tekla Structures imports absolute values of maximum forces to parts’ user-defined attributes Shear , Tension and Moment. With Yes , Tekla Structures does not import forces.

CIS/CIMSteel

Import GUID (design model)

The part GUID is included in the import.

CIS/CIMSteel

Create log file

Select Create to write a new log file and delete the previous log file each time you import the model.

Select Append (default) to add the log file information is at the end of the existing log file.

If you do not need a log file, select No.

In SDNF, this option is on the SDNF tab.

CAD (SDNF)

CIS2 status

Display log file

Select With an external viewer to display the log file in an external viewer, like Microsoft Notepad.

If you do not want to display the file, select Not viewed.

Select In a dialog box to create a separate list dialog box in which the file can only be viewed.

In SDNF, this option is on the SDNF tab.

CAD (SDNF)

CIS2 status

Import weldings

Include weldings in the imported model.

SteelFab/SCIA

Import bolt holes

Include bolt holes in the imported model.

SDNF tab

Option

Description

Import type

Part Pos_No

Enter a prefix and a start position number.

This settings relates to the Position number type setting.

CAD (SDNF)

SDNF version number

Set the SDNF format type to 2.0 or 3.0.

CAD (SDNF)

Apply cuts and fittings

Set to Yes (default) to apply cuts and fittings in the import.

CAD (SDNF)

Consider offsets

Set to Yes to create offsets. In most cases you should select Yes. No (default) positions part creation points at part end points.

CAD (SDNF)

Log file name

Enter the log file name or browse for an existing log file.

CAD (SDNF)

Position number type

The SDNF file contains identifiers that can be included in a part’s user-defined attributes, or used as part position numbers.

Select Part position if you want the identifier to become the part’s position number. Do not use the Pos_No option with this option.

Select Universal ID if you want the identifier to become a user-defined attribute for the part.

For file imports from PDS or PDMS then the Universal ID option is the normal case.

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