IDF Files

Using CircuitWorks Lite, you can import Intermediate Data Format (IDF) circuit board files (.emn, .brd, .bdf, .idb) and create solid models of the circuit boards and their components. The model is a single part with the board and each component as extruded features.

If you have SOLIDWORKS Premium, use the full version of CircuitWorks to import IDF files. See CircuitWorks Help for details.
  • Each IDF file has two parts: the board file and the library file; for example, .emn and .emp. Other possible combinations include .brd/.lib, .brd/.pro, .bdf/.ldf, and .idb/.idl. The software looks for a library file with the same name and extension corresponding to the board file. If it does not find the library file, it prompts you to browse for the file.

  • The name in the FeatureManager design tree of each extruded feature is based on the component name.
  • Components of the same type appear in the same color.
  • If the board thickness is not defined in the IDF file, you are prompted to specify a value and units.

To import IDF files:

  1. Click File > Open.
  2. Optional: 3DEXPERIENCE Users: If the Open from 3DEXPERIENCE dialog box appears, click This PC.
  3. In the dialog box, set Files of type to IDF (*.emn,*.brd,*.bdf,*.idb).
  4. To select options, click Options, select from the options, then click OK.
  5. Select the file to open, then click Open to import the file as a SOLIDWORKS document.
    A status bar displays the progress and the number of components.

IDF Import Options

You can set import options when you import Intermediate Data Format (IDF) circuit board files with CircuitWorks Lite.

To set IDF import options:

  1. Click File > Open.
  2. Optional: 3DEXPERIENCE Users: If the Open from 3DEXPERIENCE dialog box appears, click This PC.
  3. In the dialog box, set Files of type to IDF (*.emn,*.brd,*.bdf,*.idb), then click Options.
    The Import Options dialog box appears with IDF selected on the File Format tab.
  4. Select from the following options:
    Option Description
    Add board drilled holes If holes have been drilled in the circuit board, the holes appear in the SOLIDWORKS part.
    Reverse underside components In cases where import data causes the components to be rotated incorrectly, selecting this option compensates for the misplacement and allows proper location of the component features.
  5. Click OK to return to the Open dialog box.
  6. Select the file to open, then click Open to import the file as a SOLIDWORKS document.
