IGES Translation Errors and Warnings

Unable to open output file

An error occurred while opening the DGN file that you are importing the IGES file into or while opening the IGES file to which you are attempting to export. Error is caused by an invalid path specification, the existence of a write-protected file with the same filename, or other similar condition (command line or batch method only).

Aborting due to memory allocation failure

Sufficient memory to complete the translation is not available. Translating large files can require substantial amounts of memory. Because both RAM and hard disk space are used, you must add more memory or free up additional hard disk space.

Unable to open IGES file

The specified IGES file does not exist or cannot be opened.

Missing terminator section

The terminator section is not found at the end of the IGES file. This usually indicates that the specified file is not a valid IGES file or is truncated or corrupted in some way.

Invalid terminator section

The format of the terminator section of the IGES file is not valid.

Unable to create DGN file

The DGN file cannot be created because the specified path does not exist, an existing file with that filename is write-protected, or some other condition prevents the creation of the specified file (command line or batch method only).

Unable to open seed file

The seed file specified by MS_DESIGNSEED does not exist in the directory specified by MS_SEEDFILES (command line or batch method only).

Unable to open temporary file

The parameter data for the IGES file is written to a temporary file (iges.pds) during translation. This file cannot be created for some reason.

Unrecognized option

An option is specified that MicroStation cannot understand (command line or batch method only).

Invalid option format

The syntax of an option is incorrect (command line or batch method only).

Unable to open settings file

The specified settings file does not exist or cannot be opened.

Settings version mismatch

The version for the settings file does not match the version of MicroStation's IGES translator.

Unable to create settings file

The specified path does not exist, a write-protected file with the same filename exists, or the file cannot be created for some other reason.

Unable to add settings to file

An error occurs while updating the settings file, which usually indicates that the settings file is write-protected.

Unable to open specification file

The specification file does not exist or cannot be opened.

Parameter type does not match directory record

The entity's parameter data does not match the type specified in its directory record. The entity is ignored.

Invalid Copious Data Format

A copious data (type 106) entity of a form not supported by MicroStation was encountered. The entity is ignored.

Unsupported entity

An entity type in the IGES file is not supported and is therefore omitted from the DGN file.

• String constant broken before Hollerith character

• String field too long

• Hollerith character missing for string field

• No field delimiter

These errors are caused by data that does not conform to the IGES syntax specification. IGESIN attempts to infer or ignore the invalid data. However, missing or incorrect geometry can result.

• Invalid directory type

• Invalid PDS Pointer in directory record

• Invalid directory sequence

• Invalid PDS count in directory record

These errors are caused by IGES files that are syntactically correct but that contain data inconsistent with the IGES specification. In most cases, IGESIN omits the erroneous entities and continues translating.

Invalid line font (ignored)

An invalid line font was encountered. The default line style is used for the entity.

Subfigure instance error

An error is encountered extracting the subfigure definition for the specified instance. The instance is omitted from the DGN file.

Unsupported conic form

An unsupported conic form is encountered. MicroStation currently supports all conic forms specified in the IGES standard, such as ellipses, hyperbolas, and parabolas.

Invalid hyperbolic conic

A degenerate hyperbola definition is encountered. No geometry is generated in the DGN file for the conic entity.

Invalid parabolic conic

A degenerate parabola definition is encountered. No geometry is generated in the DGN file for the conic entity.

Unable to standardize conic

The conic cannot be reduced to standard form through standard rotation and translation of axis techniques. No geometry is generated in the DGN file for the conic entity.

Invalid revolution axis

The axis for a surface of revolution (type 120) is not a valid line (type 110) entity. No geometry is generated in the DGN file for the surface of revolution.

Invalid entity pointer

An invalid entity pointer was encountered in the parameter data for the indicated entity. The entity is ignored.

Invalid viewing transformation

The transformation for a view entity is not orthonormal. The view definition is ignored.

Unable to create sheet file: <filename>

The specified sheet DGN file cannot be created because the specified path does not exist, a write-protected file exists with the same filename, or the file cannot be created for some other reason. The drawing entity associated with this sheet is ignored.

Unable to open sheet seed: <filename>

The sheet seed file specified by the MS_SHEETSEED configuration variable cannot be opened in the directory specified by MS_SEEDFILES. Either the file does not exist or read access is not available. The sheet DGN file is created by copying the header or the model DGN file rather than using the sheet seed file.

Invalid weight value

An invalid line weight value is encountered for the indicated entity. The weight of the entity is set to zero.

Subfigure name changed: <Subfigure_Name> => <Cell_Name>

The name of the IGES subfigure is altered to meet the MicroStation requirement of six-character alphanumeric cell names.

Can't add cell to library

This error occurs if the active cell library is write-protected.

Can't find section pattern <CODEnn>

A section pattern that is not in the cell library “igespats.cel” is encountered. The section pattern is ignored. You can correct this by creating a pattern cell for the section and adding it to “igespats.cel” with CODEnn as the cell name (nn is the section code number).

Unable to open pattern cell library

The pattern cell library “igespats.cel” is not found. This library is required for sectioned area entities (type 230). The configuration variable MS_CELL is used to locate the cell library. Be sure that “igespats.cel” exists and that MS_CELL points to its directory.

Unsupported Associativity Form

An unsupported associativity form is encountered. The associativity entity is ignored.

Element off design plane

The geometry for an IGES entity is not included in the model plane (volume in 3D) of the DGN file and is omitted. Usually this means that the working units of the DGN file are not appropriate for the IGES file being imported. You can correct this by choosing an appropriate seed file, adjusting the working units in the Working Units dialog box, or setting Translation Units to Sub-Units or Calculate.

Maximum cell size exceeded, Subfigure dropped to components

MicroStation supports a maximum cell size of 65,000 words (1 word = 2 bytes). If an IGES subfigure exceeds this limit, it is placed in the DGN file as individual components rather than as a cell or shared cell.

No UV Curve in Curve on Surface

A type 142 (curve on surface) entity is encountered with a zero pointer for the UV curve entity. The curve is ignored. This usually causes a trim boundary to be omitted from a surface.

Unsupported Line font definition (304) form

An invalid form for a Line Font Definition entity is encountered. The font definition is ignored.

Geometry omitted by exclusion of Entity: No./No.

Entities are omitted from the IGES file because the indicated entities were excluded and there is no alternate entity type to represent it. This usually occurs only if the copious data (type 106) or point (type 116) entities are excluded.

Degenerate (zero radius) arc omitted

MicroStation DGN files can contain zero radius arc or circle elements. Because the IGES specification prohibits these entities, they are not exported to IGES.
