PCB Layout CAD : Various Convenient Functions

Import DXF/DWG

DXF and DWG can be used for reading shape data created using other CADs.
There are various usages such as importing housing data using DXF or DWG, and making Board Outlines and Keep Out Areas.

For more details about converting imported Lines and Planes to Keep Out Areas, etc., refer to Convert to Filled Object.

Compatible Formats

The following versions are compatible DXF and DWG formats.

 DXF ascii (R9, R10, R12, R13, R14, R15, R18, R21, R24, R27)
 DXF binary (R10, R12, R13, R14, R15, R18, R21, R24, R27)
 DWG (R12, R13, R14, R15, R18, R21, R24, R27)

The following are PCB documents compatible with Import DXF/DWG.



Reading DXF/DWG Data

This is the method for reading housing data using DXF or DWG for making Board Outlines.

Reading a Board Outline Using DXF/DWG Data
(1) [File]
=> [Import]
=> [Import DXF/DWG].
=> The "Import DXF/DWG" screen will open.
(2) Click "..." next to Import File => The "Open" screen will appear.
(3) Select a DXF file.
(4) Click "OK".
(5) From the DXF layer, select the Board Outline layer and the layer that you want to read (here, "Other:Board").
* Multiple Selection is possible.
(6) Click the "=>" button.
(7) Click "OK".
  The DXF data will be read.

There is also Create Restricted Area Automatically that automatically creates the Keep Out Area inside and outside of the Board Outline line.


Import DXF/DWG Screen

Item Description

Import File

Specifies the DXF/DWG file to be read.


Specifies the Unit for DXF/DWG import. Set the same Unit as for Export DXF/DWG.

Line Width

Specifies the Line Width of lines for DXF/DWG import. (Only the Default Line Width will be applied.)

Text Line Width

Specifies the Text Line Width of Text for DXF/DWG import. (Only the Default Line Width will be applied.)

Specify the tolerance

Specifies the tolerance of the coordinates where objects in DXF/DWG are input.
By specifying it, the coordinates of objects existing within that tolerance range will be corrected,
and the objects will be placed at the same coordinates.
It is possible to maintain a connection between lines
even when they become unconnected due to an error caused by DXF input/output.

Import Layout

Select "*MODEL_SPACE" or "*PAPER_SPACE" for layout block. Set the same setting as for Export DXF/DWG.

DXF Layer

Displays the layer specified in the read DXF/DWG file as a list.


PCB sheet layers are displayed as a list. Data for the assigned layer is read to the specified layer.

Assigned Layer

The Assignment status of the DXF layer can be confirmed.
