Load
  • Default PCB Width - use this field to determine the width placement of the origin and how much the initial area will be positive when a new session is started. The extent of a working area is 65" x 65", so any initial positive area between zero and the full extent will be accepted.
  • Default PCB Height - use this field to determine the height placement of the origin and how much the initial area will be positive when a new session is started. The extent of a working area is 65" x 65", so any initial positive area between zero and the full extent will be accepted.
  • Center image in database - enable this option to ensure that the extents of the loaded entire image are calculated and centered within the CAM document.
Edit/Info/Aperture
  • Auto Repeat Functions - enabling this option ensures that repeat editing and drawing functions occur until you either press Esc or choose Cancel from the right-click menu. This option can be useful when you require a series of similar draws or edits and wish to avoid restarting each function manually.
  • Display Aperture List in MILS (English Units) - enable this option to display inches in MIL (1 = 0.001") units for all aperture sizes (including DRC, and other features that request sizes to be inputted).
  • Object Snap within pickbox (Fuzzy Mode) - enabling this option allows you to snap to any existing endpoints within the pickbox.
Log file generation preferences
  • Default log files location - define the default log files location to store generated log files. Click on the button to set the path. Ensure the Enable log file generation option is enabled if you wish to store generated log files.
  • Enable log file creation (information, warnings, errors) - enable this option to store generated log files.
  • Open log file after process ends - use the drop-down to ensure that log files always open when errors or warnings are found.
Polygon Options

Select Polygons when Highlights Nets - if you've extracted nets from Gerber data, you may enable this option to select target polygons when related nets are highlighted.


View / Language

The CAM Editor – View / Language page of the Preferences dialog includes controls to choose translucent viewing, how to display the current layer and layer sorting, the language to be used for drawing text, and customize layer colors when in the CAM Editor.

View
  • Translucent Viewing Default - enable this option to start the CAM document editing session with the translucent viewing enabled.
  • Draw Current Layer Last - enable this option so the current layer is displayed on top of all other layers.
  • Arc(s) slicing resolution (Degrees) - this field controls the displayed arc resolution for circular interpolation (true arcs). Arcs will always retain their true arc information but will be displayed as straight line segments to boost display speed. At any time, you can query on an arc to check the arc information is still preserved.
  • Sort Layers Tree (Alphabetically) - use to choose how the layers are sorted alphabetically. 
Language For Drawing Text

Use the drop-down to choose the language when drawing the text on the CAM document.

Colors

Colors - click to select the color to customize the CAM Editor's layers.


DRC

The CAM Editor – DRC page of the Preferences dialog allows you to set the minimum clearance distance between a thermal and another flash on a plane layer within the CAM design space.

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.

Miscellaneous

The CAM Editor – Miscellaneous page of the Preferences dialog includes options relating to the miscellaneous settings of the CAM Editor, such as setting file extension names that need to be imported, quick load settings, and custom aperture accuracy.
