Gerber Import (Default)

• RS-274 - clicking this button cycles through the available Gerber formats: RS274, RS274X, or Fire9000.
• Import Settings - click to open the Gerber Import Settings dialog, which you can use to determine measure units (English or Metric), Digits formats, and Zero Suppression types, among other options.
• Advanced Options - click open the Import Gerber Options dialog to set up options such as using 360 Degree Arcs as default and define the End of Gerber Block settings.

Gerber Export (Default)

• RS-274 - clicking this button cycles through the available Gerber formats: RS274, RS274X, or Fire9000.
• Export Settings - click to open the Gerber Export Settings dialog, which you can use to determine measure units (English or Metric), Digits formats, and Zero Suppression types, among other options.
• Advanced Options - click to open the Export Gerber(s) dialog, where you may determine the separation of composite layers into individual files, set up Fire9000 resolution, and convert polygons to vector fill, among other options.
• Suppress comments (remove G04 commands) - enable if you want to suppress G04 commands as comments when Gerber data is being exported from a CAM Editor document.

Export 2 PCB - Options

• Create Fills (only if rectangular) - choose this option and fills are created for rectangular polygons when exporting CAM Editor designs.
• Created Hatched Polygons - enable this option to ensure copper pours consisting of tracks and arcs are created when exporting CAM Editor designs. Click the Hatched Polygon Options button to set up polygon settings.
• Create Solid Polygons - enable this option to ensure polygons (copper pours) are created when exporting CAM Editor designs. Click on the Solid Polygon Options button for additional settings.
• Hatched Polygon Options - click to set up the hatched polygon such as the grid size, track width, minimum primitive length, and removing dead copper when importing or exporting designs that contain polygons.
• Solid Polygon Options - click to define the attributes for the solid polygon such as copper islands, narrow copper necks, and how to pour polygons over the same net.
• Create PCB DRC Rules from CAM DRC Checks - enable to use the DRC rules for PCB from the CAM DRC checks.
• Select the imported layer that will be used to create the PCB BoardOutline (from the biggest closed primitive) - use the drop-down to select the desired layer.

Options

• Optimize Exported Gerber, Drill, Rout file size - enable this option to optimize the size of the exported file of Gerber, Drill, or Route data.

Import - handling of identical layer types

• Use existing layer - choose to use the same existing layer type when Gerber, NC Drill, or IPC-356-D files are being imported with identical layer types.
• Create new layer - choose this option to create a new layer type when Gerber, NC Drill, or IPC-356-D files are being imported with identical layer types.
