ECAD Import Module Updates

Automatically Exclude Objects Outside the Board

When importing copper layers from IPC-2581 and ODB++ files, you can automatically exclude symbols located outside a specified distance from the edge of the board. There is an Ignore objects outside of board check box that, when checked, enables an expression field to define the offset distance.

A PCB model is imported into COMSOL Multiphysics and two objects located outside the board are excluded.

Reload Layer Information

A new button, Reload Layers, is now available when importing the GDS-II, IPC-2581, and ODB++ formats. Use this button to reread the layer information from the ECAD file if the file has changed on the disk after the last time it was imported.
