Import (DXF): Edit Parameters Dialog

The Edit Parameters dialog allows you to configure, import and save the parameters for importing a DXF file.

Item   Description
Import parameters   Allows you to load parameters that are stored in a file, using the Open dialog.
Export parameters   The parameters that you configure in this dialog can be saved to a file, using the Save As dialog.
Layer Mapping   Allows you to map the layers in an imported DXF file to the layers in your design. To add a combination of layers, select Add Row from the assist menu.
  DXF file for reference Specify a DXF file to use as a reference for mapping the layers in the imported DXF file. The layers in the specified DXF file are displayed in the DXF layer configuration box. By default, the file is selected that you specify in the File box, in the Import (DXF) dialog.
  DXF layer configuration Displays the layers in the DXF file that you specify in the DXF file for reference box.
  Adds the layer that is selected in DXF layer configuration box to the Layer to convert box.
  Layer to convert Allows you to map the layers in an imported DXF file to the layers in your design. To map additional layers, right-click in the Layer to convert box and select Add Rows on the assist menu. Specify a layer in the displayed Select Layer dialog. This dialog is launched by pointing the cursor in this column, and clicking the displayed button.
ItemDescription
DXF layer nameShows the name of the layer in the DXF file that is being imported, and allows you to edit it.
Layer nameSet the layer in the design by pointing the cursor to this column, and clicking "...".
  Moves the row that is selected in the Layer to convert box to the Layer not to convert box. Select multiple rows using the CTRL or Shift keys.
  Moves the row that is selected in the Layer not to convert box to the Layer to convert box. Select multiple rows using the CTRL or Shift keys.
  Layer not to convert The Layer not to convert box allows you to save the settings in the Layer to convert box.
  • The values in the Layer not to convert box are read-only.
  • Only the settings specified in the Layer to convert box are referenced during the import process.
ItemDescription
DXF layer nameThe name of the layer in the DXF file.
Layer nameThe layer in the design.

Import

  Allows you to specify how objects in the DXF file are converted during the import process, and specify the units associated with values in the imported DXF file.
  Conversion figure Specify how objects in the DXF file are converted during the import process.
ItemDescription
ScaleSet a scale parameter between 0.01 and 100.0 to enlarge or reduce an object that is imported from a DXF file.
  • A value of 0.5 reduces the size by half.
  • A value of 2.0 makes it twice as large.
Tolerance for converting curved line

Specify the maximum tolerable error for the conversion of curved lines. During the import process, curved lines that cannot be drawn are approximated by multiple, short, straight lines in a process called curved line conversion, as shown below. The arrows indicate the maximum tolerable error.

Convert circle to area fill
  • Selected: circular objects are imported as circular area fills.
  • Not selected: circular objects are imported as circle shape lines.
Convert open polyline to area fillAllows you to control whether polylines are converted into area fills by specifying a value in the Tolerance for open polyline box.
  • Selected: the Tolerance for open polyline box is made available. This allows you to set the maximum distance between the start and end points of polylines. This determines whether they are converted into area fills.
  • Not selected: polyline objects are imported as polylines.
Tolerance for open polylineSpecify the maximum distance between the start and end points of polylines. This value determines whether they are converted into area fills.
  • If the distance between the start and end points is smaller than the specified value, then polylines are imported as area fills.
  • If the distance between the start and end points is equal to or greater than the specified value, then they are imported as polylines.
  Unit Specify the units that are associated with values in the imported DXF file.
ItemDescription
DXF file unit

mm: values in the DXF file are imported as mm.

inch: values in the DXF file are imported as inches.

micron: values in the DXF file are imported as microns.

mil: values in the DXF file are imported as mil.

OK   Saves the values that you set in the Edit Parameters dialog and closes the dialog.
Cancel   Closes the Edit Parameters dialog without saving your settings.

 

Note
  • If you specify the same DXF layer name in multiple rows in the Layer to convert box, it is only imported to the layer shown in the highest row of the Layer name column.
  • The following object elements in DXF Release 12 are not supported:
  • POINT
  • SHAPE
  • VIEWPORT
  • The following object elements in DXF Release 14 are not supported:
  • POINT
  • SHAPE
  • VIEWPORT
  • MLINE (Multiline)
  • 3DSOLID (3D solid)
  • IMAGE
  • LEADER
  • RAY (Radial)
  • REGION
  • Because each footprint layer has specific input restrictions, you must correct the objects for area fill, line and character before adding them (see below).
