Importing a STEP AP203 / AP214 File

This task shows you how to import to a CATPart or CATProduct document
the data contained in a STEP AP203 / AP214 file. 

It is also possible to insert a STEP file as an existing component in a CATProduct. 


 
Regarding AP214, both STEP AP 214 IS and STEP AP 214 DIS files are read.
The table entitled What about the elements you import ?
provides information on the entities you can import.

You can find further information in the Advanced Tasks:

and in the Customizing STEP Settings chapter.

Statistics about each import operation can be found in the report file and the error file.

 

  1. Click the Open icon  or select the File->Open command.

The File Selection dialog box is displayed.

 

  1. Insert/Existing component command.

The File Selection dialog box is displayed.

 

  1. Set the .stp or .step extension in the Files of type field.  

This displays all .stp or .step files contained in the selected directory :

 

 

  1. Select the .stp or .step file of your choice (MoldedPart.stp, in our example) and click Open.


 

 

  A progress bar is displayed.

You can use the Cancel button to interrupt the transfer at any time.

What is then displayed depends on the contents of the STEP file.

For the File/Open command:

  • If the STEP file contains a normalized assembly structure,
    a CATProduct document is created.
  • If the STEP file does not contain any geometrical and topological data,
    the components will be visible only  in the Specification Tree.
  • If the STEP file contains also geometrical and topological data,
    all the components will be present in the Geometry Space and in the Specification Tree. 
  • If the STEP file contains only geometrical and topological data, a CATPart document is created.

The geometrical elements of the faces, which could not be transferred,
are created in the NO SHOW space. In the NO SHOW space, you can
visualize the Surface supports and the 3D Curves).

 

For the Insert/Existing component command:
  • if the STEP file contains no assembly information, it is converted to a CATPart,
  • if the STEP file contains assembly information, it is converted to a CATProduct
    referencing several CATPart documents.

The resulting document is inserted in the current CATProduct document,
and the graphic window is updated (specification tree and geometry).

 

  • The reference to the STEP file is lost, so any update of the STEP file will have no effect
    in the CATProduct.
 
  • For both commands, the reference planes are hidden.
  • A Geometrical Set is always created. It may be empty:
    • it will contain the valid surfaces imported, if any.
    • it is empty if there is no valid surfaces, e.g. when the element imported is a solid,
      or when all surfaces are invalid.
    • invalid surfaces are sent to a specific Geometrical Set (FaceKO#xxx)
Several STEP options can be customized:

Report file

After the recovery of STEP files, the system generates:

  • a report file (name_of_step_file.rpt) where you can find references about the quality of the transfer 

  • and an error file (name_of_step_file.err) .

These files are created in a location referenced by the CATReport variable. Its default value is 

  • Profiles\user\Local Settings\Application Data\Dassault Systemes\CATReport on NT (user being you logon id)

  • and  $HOME/CATReport on UNIX.

Always check the report and error files after a conversion !
Some problems may have occurred without been visually highlighted.

Example of a report file 

(Some lines have been replaced with ...)


Legend

OK = Transferred
KO = Not Transferred
NS = Unsupported
OUT = Out Of Size
DEG = Degenerated
INV = Invalid
  • "OUT" entities are OUT of model size. Most of the time, these entities are curves
    and they are out of the V5 model space. These entities are not created.
  • "INV" entities are Invalid entities, that is to say their description within the STEP file
    is invalid (STEP syntax rules are not respected,...). These entities are not created.
  • "DEG" entities are degenerated entities. They are solids (MANIFOLD_SOLID_BREP) or
    Shells (OPEN_SHELL), or Curves (LINE, CIRCLE,...).
    Degenerated solids are incomplete solids (at least one Face misses)

Report messages

  Here are some of the messages that may appear:
  • Too many cuts on face boundary.
    Tip : Use topological reduction option (in IGES) or curve optimization (in IGES or STEP) - see User's Guide
    These options are accessible via Tools/Options/Compatibility/STEP dialog boxes, in
    the Continuity optimization of curves and surfaces section.
    Select the Advanced optimization option and push the Parameters... button.
    For more information, click on the link on STEP above.
  When the Continuity optimization of curves and surfaces/Advanced optimization option in T
ools/Options/Compatibility/STEP
is active, the following warning messages may appear in the report file:
  • The BSpine Surface is not C1: Approximation of the surface is impossible!
    This is just a warning, the surface is imported but is not approximated.
  • The deformation found of the surface approximation (which is calculated by isoparameters) is : xx millimeters.
    This indicates that the real deformation found is higher than the Deformation value
    you have entered in the Parameters box and that the approximation could not be performed.
    When this occurs for several entities, you will find the following information message at the end of the report file:
  • For a better approximation of BSpline surfaces, you can use a "Curves and surfaces approximation"
    Deformation value of at least : xx millimeters
    You can enter this value in the Parameters box of the
    Continuity optimization of curves and surfaces/Advanced optimization
    option in Tools/Options/Compatibility/STEP.

What About The Elements You Import ?

Exchanging 3D Geometry

One of the current primary uses of the AP214 Standard is to exchange geometry.
The STEP Interface enables users to exchange the B-REP of exact solids.
The exchange process is based on AP214. This application protocol is very similar to AP203 as
it shares the same resources expressed in the PART 42.

 

  • Conformance Classes 2,3,4 and 6 are supported in AP203.
  • Conformance Classes 1 and 2 are supported in AP214
    (assembly and 3D geometry / topology management).

Exchanging Visual Presentation of 3D Geometry

Another use of the AP214, AP203 edition2 or AP203 with extensions Standards is to
exchange visual presentation information. The STEP interface enables users to exchange
visual presentation of exchanged geometric elements.

Please remember:

  • Units:

As the unit system used in Version 5 is MKSA (radians, mm) data from all STEP files will
be converted into such units.

  • Layers:
  • A layer is created in your application for each layer present in the STEP file.
  • All entities included in a layer in the STEP file are included in the corresponding layer.
  • A layer over 999 is replaced by layer 0.
  • Color:
    • Color exchange is supported.
    • STEP AP214: When an entity OVERRIDING_STYLE_ITEM exists in the STEP file for a given face,
      this color overriding is taken into account: the color of the face is overridden. 
  • Lines:
    • The line type is taken into account.
    • If the requested line thickness is defined in your environment, this thickness is taken into account,
      else the nearest predefined thickness is taken.
  • Points:
    • Point styles are mapped as follows:
STEP point style  

V5 point style

cross, triangle  

plus

 
circle
 
square
asterisk
 
dot
 

Assemblies

STEP files containing assembly structures can be imported.
STEP assemblies are mapped with the Product Structure. Geometry can be defined: 

  • in STEP in the same file, 
  • or in STEP in external files (AP 214 external references mechanism).
    The files referenced are STEP files. External references are supported with STEP AP214 and AP203 edition2 only.  
  • or in CATIA in external files. The files referenced are CATIA files.
    External references are supported with STEP AP214, but they are not with STEP AP203.  
  • or by links to CATPart, model or cgr files via Product_definition_with associated_document entities.
    Assemblies generated by V4 CATASM and referencing to .model files or cgr files are supported.
   
  • The physical structure of an imported assembly can be defined by one or several CATProducts
    (one for each node) depending of the option selected
    (See the Assemblies physical structure option about the import STEP files containing sub-assemblies).
  • CATPart files are linked to the CATProducts as instances of Parts.
  • Model files or cgr files are linked as Shapes.
  • In the case of referenced files, those files must be in the same location than the root STEP file,
    or be accessible via the search order.

 

The attributes of products are taken into account as follows:
STEP V5     
PRODUCT.ID Part Number
PRODUCT.NAME Definition
PRODUCT.DESCRIPTION Description 
PRODUCT_DEFINITION_FORMATION.ID Revision

The attributes of instances of products are taken into account as follows:

STEP V5
NEXT_ASSEMBLY_USAGE_OCCURRENCE.ID Component/Instance name
NEXT_ASSEMBLY_USAGE_OCCURRENCE.DESCRIPTION Component/Description
 

Groups

  • For each APPLIED_GROUP_ASSIGNMENT pointing to a group and a list of entities in the STEP file,
    a Selection Set is created.  This Selection Set is named with the name of the pointed GROUP entity
    and includes all pointed entities.
  • The transfer of groups can be activated/de-activated via the Groups (Selection Sets) option.
