PADS PCB Library ASCII File Import Options

Modified by Susan Riege on Apr 25, 2018

The PADS PCB Library ASCII File Import Options dialog

Summary

The PADS PCB Library ASCII File Import Options dialog is used to map PADS PCB layers to an Altium Designer layer. The dialog also gives access to the Importer settings dialog in which the user can control design rules, missing vias and keep-out conversions during the import process.

All used PADS PCB layers must be mapped to an Altium Designer layer prior to import.

It should be noted about how the layers are mapped on import for PCB designs. Layer Mapping is a mapping between the names of the PADS PCB layers and Altium Designer PCB layers. You can change as many mappings as you want as only suggested default mappings are given. This mapping is used by the Import Wizard to build the layer mapping for each PCB that can then be individually customized. The rationale here is that should you wish to import 10 PCB designs and you want to map the layer Assembly 1 to Mechanical Layer 1, you would not have to customize each of the 10 PCB designs in order to get the right layer mapping. The customized layer mappings are stored in a *.INI file.

The advantage to importing in this manner is that batch management of layer mapping saves time when importing multiple designs. In this instance, the default layer mapping will be saved to your Preferences.

Default Layer Mapping is not always intelligent with differing structures in designs, so some manual changes may be required.

Access

The dialog is accessed by clicking Edit Mapping on the Default PCB Specific Options page of the Import Wizard (File » Import Wizard) when importing PADS ASCII Design Files. 

Options/Controls

          • Signal Layers - select to open a sub-menu of signal layers:
            • Top Layer - click to change the selected layer to the top layer.
            • Mid Layers - select to open a sub-menu for all available layers from which you can choose.
            • Bottom Layer - click to change the selected layer to the bottom layer.
          • Silk Screen Layers - select to open a sub-menu of silk screen layers from which to choose:
            • Top Overlay
            • Bottom Overlay
