The Export EDMD Baseline dialog


The Export EDMD Baseline dialog is used to create an IDX file (MCAD Baseline.idx). This file type is used for collaborating between ECAD and MCAD domains. Altium Designer facilitates this collaboration using the MCAD IDX Exchange extension, which is necessary to access this dialog.


The dialog is accessed by performing the following steps:

  1. From the PCB editor, click the Panels button at the lower-right of the design space then select MCAD IDX Exchange or click View » Panels » MCAD IDX Exchange from the main menus.
  2. In the MCAD IDX Exchange panel, click the Export Baseline button.

The MCAD IDX Exchange extension (shown below) must be installed to access this dialog.

The extension can be found on the Purchased tab of the Extensions and Updates page (accessed by using the  drop-down at the top-right of the design space then choosing Extensions and Updates).


  • Ignore Duplicate Pad Designators - enable to ignore pad designators that are duplicated when exporting.
  • Export Copper - enable to include copper in the export.

    Exporting copper makes the IDX files much bigger and slower to process on the MCAD side. In addition, the IDX technology does not support change detection for copper objects. 
  • Warning - click to open a text warning regarding exporting copper.
  • Export Tracks, Export Copper Regions, Export Vias, Export Pads, Export Internal Layers - enable the objects you want to export into the file.  Options that are not selected will not be included in the exported file. These options are accessible only when Export Copper is disabled (not checked).
