Automatic CAM Editing Tools
Venting & Thieving
Generate Venting and Thieving Patterns and Solid Fill line drawings at any angle. Mix patterns for different layer types in a single job. Use variable border types for copper balancing. Pick from among the following patterns:
· Solid
· Dots
· Interlocking Dots		 · Positive VPI
· Negative VPI
· Starburst		 · Hatched
· Crosshatched.

Filleting
Add Snowman or Teardrop Filleting at the intersection of pads and traces. Filleting can be added at variable size, percentage and position. Perform multiple operations on multiple layers simultaneously.

Fill Polygons
Fill simple or complex polygons. Fill inside or around circuit elements. Define fill and keep out areas with Nested Polygons. Automatically identify or repair Open, Crossed, or Overlapped polygons. Fill with one or two D Codes. Use the following fill patterns:
· Solid
· Hatched		 · Crosshatched
· Fill Inside Elements

Soldermask Generation
Automatically duplicate Padmaster pads using swelled D Codes in a Soldermask layer. Use existing D Codes for the Soldermask pads or generate new D Codes.

Overlap Correction
Retract traces to pad borders or edges of holes in circular or square pads. Transfer covered or duplicate traces and pads. Process multiple layers simultaneously.

Global Draw to Flash Pad Conversion
Convert drawn pads into standard or custom D Codes. Process single or multiple layers simultaneously using one of these two methods.1) Stand alone pads, such as elements found on soldermask layers, will allow you to quickly convert all drawn pads in a selection into standard or custom shapes. 2) Only flash elements exposed by a guide, such as the soldermask, leaving all other pads and traces unchanged.
Snap to Padmaster
Automatically snap misaligned data, layers of different resolution, or scanned artwork to a padmaster or drill file. Snap all or a selected part of the loaded data. Snap both pads and traces, or pads only, or elements of a selected D Code only. Process multiple layers simultaneously.

Copper Area Calculation
Analyzes the copper area of any combination of layers, venting patterns, test coupons, targets, and drill data. Capable of including the copper area of plated through-holes using the hole diameter and PCB thickness. Bitmap analysis accounts for element overlap. Text Copper Area Report file shows the analysis results in square inches, square cm, or percentage of analyzed area.

Centroid Data Generation
Calculates the component location of groups of lands converted to a single D Code. Outputs an ASCII file of component numbers and X, Y locations. Creates a Gerber file of Shape or Component outlines.

Delete Non-Functional Pads
Automatically deletes or transfers unconnected pads and padstacks. Uses tolerance values to determine whether pads are unconnected or stacked. Exempts some specified classes of pads from deletion or transfer. Operates on multiple layers simultaneously.

Clip Silk Screen
Clips silkscreen traces to clear soldermask pads. You have the option to automatically discard traces that have been clipped to shorter than a specified length.

Generate Outline Data
Generates trace outlines of the elements of a layer. Outlines can be swelled by a margin value. Outline data from a soldermask layer can be used to generate a laser cutting path for making stencils.

Arc Conversion
· Break 360-Degree Arcs into Quadrant Arcs
· Approximate Arcs with Chords

Sort Elements by Proximity
· Hypotenuse and Max XY Methods.
Design Rule Checking
Run a Design Rule Check on all or only a selected part of the loaded data. The operation outputs a text Error Summary Report and flags error locations in the loaded data with selected error elements. Check the following Design Rules:
Vector-Based DRC
Vector DRC uses the Gerber description of the position, size and shape of elements to determine clearance and contact between elements. You can run a vector DRC on all or only a selected part of the loaded data. The operation outputs a text Error Summary Report and flags error locations in the loaded data with selected Gerber error elements.
Check the following Design Rules with vector DRC:
· Air Gap (Trace-Trace, Trace-Pad, Pad-Pad)
· Annular Ring Gap (Drill-Outer Layer, Drill-Plane Layer, Drill-Other Layer, Drill-Thermal)
· Power-Ground Shorts (Drill contact on more than one power or ground layer)
· Soldermask Clearance (Mask-Outer Layer Pad, Mask-Outer Layer Trace)
 · Outline-Copper Area Clearance
· Pad-Pad Contact
· Centerline Disconnection (Trace-Trace, Trace-Pad)
· Trace Intersections
· Unterminated Traces
Netlist Extraction
Vector-Based Netlist Extraction
Vector Netlist Extraction uses the Gerber description of the position, size and shape of elements to determine if the elements intersect. The Vector Netlist Extraction routine defines elements that intersect to be in the same net.
· Buried and Blind Vias
· Automatic power and ground short identification		 · Multiple power and ground splits

The Vector Netlist generates a variety of netlist information and files:
· Lavenir Format 0 Netlist
· Lavenir Format 1 Netlist
· Lavenir Format 2 Netlist (IPC-D-356)
· Lavenir Format 3 Netlist
· Lavenir Format 4 Netlist (IPC-D-356 with Trace Data) 		· Net Count Report
· Gerber Reference Plot
· Short Circuit Report
· Short Circuit Gerber Plot
