About Export Mode

Export dimensions as Dimensions

If the Export dimensions as Dimensions check box is selected, dimensions are exported as follows:

• The graphic representation is always created in addition to the semantic representation. Thus when opening the result with semantic dimensions with AutoCAD, the graphic representation is first kept but the dimension may be rebuilt at any edition, while taking into account the default dimension style.
• Default dimension style entails that most graphic attributes (such as color, display format of the dimension value, type of arrow, space...) of the dimensions are lost. The default dimension style depends on the current export unit (INCH, mm,...).
• Horizontal and Vertical projected linear dimensions are created as DXF "rotated dimensions". If the attach points of the dimension are distant compared to the projected distance, there may be a numerical error in the measured dimension. If this occurs, reduce the number of digits displayed in the opening system.

Export Blocks

Those three options define how blocks are exported:

• None: The export does not create any block in the DXF/DWG file.
• One level: Details are retrieved through their Dittos. A Detail not referenced by a Ditto is thus lost, a Detail referenced by several Dittos is duplicated in BLOCKS. The entities included in a Detail are not structured into sub-blocks. The graphical representation of each Ditto is exported to an INSERT/BLOCK.
• Full: Each Detail instantiated by a Ditto inside a sheet is translated as such. If necessary, the name of the Detail changes according to the following rule:
  • If the 3DEXPERIENCE Detail name is an empty string, the name of the corresponding BLOCK is BLOCK_EMPTY_NAME_ followed by a number to guarantee the uniqueness of the name (whatever the Version might be).
  • If the 3DEXPERIENCE Detail name is not en empty string, and if Version is set to DXF/DWG R12/R13/R14, only the first 20 characters are exported (f required, they are followed by an underscore '_' and a number to guarantee the uniqueness of the name). The only characters exported are letters (from 'a' to 'b' and from 'A' to 'Z') all converted in upper case, digits (from '0' to '9') and the following special characters: the hyphen '-' and the underscore '_'. All others characters are exported as underscore '_'.
  • If the 3DEXPERIENCE Detail name is not en empty string, and if Version is set to DXF/DWG 2000 or higher, only the first 250 characters are exported (if required, they are followed by an underscore '_' and a number to guarantee the uniqueness of the name (with the same constraint about characters as above except that lower case letters are not modified in uppercase letters).

  Details which are not directly defined inside the Drawing representation (e.g. coming from a catalog) are exported as one INSERT/BLOCK per Ditto visually faithful.

  For each supported Detail:

  • Ditto is positioned inside the Sheet coordinates system according its insertion point and its transformation.
  • The graphical properties (color, line type, line thickness) of each Ditto are visually kept (no overload will be seen).
  • The Detail entities keep their layer according to the DXF layer semantic export option (the name or the number is exported).
  • Contained geometric entities like Nurbs, Spline or ellipse are exported semantically (not as polylines).
  • Nested Detail are exported as such.
  • Invisible entities are not exported.
  • Only the Detail instantiated inside the sheet are exported.
  • The number of exported entities is written in the report file. One export Detail corresponds to only one BLOCK with as many INSERTS as exported Dittos.

Layers

You can choose to export Export layer number and Export layer name.

With the exception of the None layer, each 3DEXPERIENCE layer is defined by three data:

• Its number
• An optional name
• An optional comment

In AutoCAD applications, layers are defined by:

• A name
• A status
• Some graphical attributes.

You can choose how you want to export layer number:

• Export layer number: Each 3DEXPERIENCE layer is exported with an AutoCad layer name that is the number of the 3DEXPERIENCE layer
• Export layer name
  • If the 3DEXPERIENCE layer name is an empty string, the 3DEXPERIENCE number is exported (whenever the AutoCAD export version chosen).
  • If AutoCAD R12, R13 or R14 is selected as the export version, then only the first 26 characters are exported. The only characters exported are:
    • Letters (from 'a' to 'b' and from 'A' to 'Z') all converted in upper case
    • Digits (from '0' to '9')
    • And the following special characters: the hyphen '-' and the underscore '_'
    • All others characters are exported as underscore '_'.
  • If AutoCAD 2000 or a version above is selected as the export version, then only the first 255 characters are exported, with the same constraint about characters as above, except that lower case letters are not changed to uppercase letters and space character is authorized.
  • Some different layers could be translated into the same AutoCAD Layer. When this case happens a message is added inside the report file.

Export View as Viewport

When selected, this option exports Drafting Views as AutoCad Viewports. Drafting Views properties and structure, including visual clipping, are exported as follows:

• All the entities of the Drafting View are exported to the Space Model of the DXF file, at a 1:1 scale and 0° angle. A Viewport is created for each View in the Paper Space. The Viewport is positioned in the Paper Space as the View in the Sheet, with scale and orientation management.
• All the entities of the Background View are exported into the Paper Space representing the Sheet.
• Views are positioned along the X-axis of the Space Model, without intersection.
• The disposition of the Views in the Model Space is given for indication, but is subject to change.
• The exported visual clipping supports only geometrical entities, not texts or dimensions.
• Visual clippings found in Drafting Views with an angle are not exported.
• The position of geometries in the Model Space is not guaranteed.
• Blocks of details sheet are exploded in the Paper Space sheet.
