Jumbo Tracer Details

  • A product developed by The Logic Group and GTCO Calcomp for tracing large templatespatterns/parts using multiple digitizing tablets and Logic Jumbo Trace software
  • Up to 16 boards can be connected and used at one time to digitize patterns up to 88' in size (28 m) in size
  • Easily and accurately trace patterns and create DXF, DWG, PDF, EPS, SVG vector graphic files for loading into CNC, CAD, Cutting, and Apparel software and hardware machines
  • The Logic Group Logo
  • Tracing can be freehand drawing, point to point, lines, arcs, circles, and curve fitting
  • 0.01" (10/1000 .254 mm) accuracies standard with higher 0.005" (5/1000 .127mm) accuracy boards available
  • Accuracy across boards maintained through exclusive calibration sheets. During setup, users digitize points on the calibration sheets placed between connecting boards. defining proper alignment
  • The Logic Group Logo
  • Exclusive mounting hardware for connecting multiple boards in any user chosen configuration - rows, columns, squares, and L shaped. Boards can be rotated 90 degrees for additional setup variations. Modular system makes reconfiguration of tablets easy.
  • Cordless pen stylus or cordless cursor allows easy digitizing across boards
  • Thick blue plexiglass overlays included to offset digitizer edge brackets (extrusions) to allow a smooth surface of multiple digitizers to be at same height. Metal, cloth, and paper templates placed across boards lay flat allowing extremely accurate digitizing
  • The Logic Group Logo
  • Gaps in digitizing caused by digitizer borders can be easily filled by moving template or part, realigning, and tracing gaps. A complete accurate tracing of template is possible with the Jumbo Tracer
  • With 16 digitizer boards, patterns up to 4'x96' (1.3x30m) can be traced when placed in a single row or 18'x22' when placed in 4 rows


Designed specifically for the CNC, CAD, Cutting and Pattern Making industries, The Jumbo Trace Digitizing System consisting of multiple digitizing tablets and Jumbo Trace digitizing software by The Logic Group can quickly and easily trace any outline, template, object, or part and create a DXF graphics file on your computer ready for use by any CNC or cutting software and machine.

Tracing objects and creating computer graphics files is fast and easy: 1. Place item on digitizing tablet 2. Choose whether to digitize points, lines, arcs, or circle 3. With digitizer pen trace the object 4. Repeat last 2 steps as needed 5. Save DXF file 6. Load file into CNC or Cutter software That's It!!

A typical Jumbo Trace Digitizing System comes with the following components: Digitizing Tablets, Pen Stylus or Cursor, Jumbo Trace Software, Connecting hardware, Calibration Sheet

Sample Uses of Jumbo Trace: Metal Fabrication, Glass Cutting, Upholstery, Countertops, Die Cutting, Custom decays and Signs Packaging and Pattern Making Custom Motor, Aircraft, and Boat Parts Embroidery And Many More...

Jumbo Trace System works with a variety of CNC machines Plasma Cutters, Laser Cutters, Waterjets Printers, Plotters Fabric and Cloth Cutters

Jumbo Trace Software can create DXF, DWG, Gcode, NC, SVG, EPS, PDF and other graphics files of the traced patterns

Tracing Methods

  • Tracing - Freehand drawing, continuously trace an edge of a part or pattern. For example continuously trace a heart or a pattern of a seat cushion
  • Tracing Methods Freehand
  • Lines and Arcs - digitize points and have the points connected with lines or arcs. For example digitize the outline of an ice cream cone with a V at the bottom and a semi-circle at the top. Digitize three points for the cone and three points for the arc (actually two points for the arc because it uses the last point digitized of the cone for the first point of the arc
  • Tracing Methods Freehand
  • Combination - Toggle between freehand tracing and points connected with lines and arcs
  • Point to Point
  • Circles - Digitize any three points on a circle (ie at the top, lower left and lower right and the software uses those three points to calculate and display the circle
  • Curve Fitting - Digitize a series of points along a smooth curve and the software fits a Bezier curve-fit line through all the points
  • Tracing Methods Freehand


  • Trace object or drawing and create DXF graphics file
  • Fast and easy
  • Very accurate with .01" standard, higher accuracies available including .005"
  • Useful in hundreds of different CNC and Cutting machines including routers, waterjets, plasma, metalworking, manufacturing, wood-working, plastics, furniture, upholstery, garments, machining
Logic Trace Cnc Dxf
  • Useful in hundreds of different industries metalworking, manufacturing, wood-working, plastics, furniture, upholstery, garments, machining, sign-making, boat manufacturing
  • Trace lines, arcs, curves, points
  • Trace point to point or continuously
  • Generate DXF files with Arcs and Lines or Polylines
  • Generate Gcode files
  • Convert DXF files to other formats
  • Trace object on digitizer using pen stylus or cursor
  • Place object directly on digitizer or trace from template on digitizer
  • Create accurate graphics files of objects in minutes
  • Normal scaling is 1:1 but different scaling possible
  • English and metric units
  • See digitized image on screen
  • Arcs created by digitizing endpoints and any middle point
  • Complex curves can be created using polylines or digitizing multiple points and arcs automatically created
  • See all points and results on screen including arc data.

Digitizing Tablets & Accessories

A Digitizing Tablet is an electrical-magnetic board and pointer (pen or cursor) that can send highly accurate XY points to a computer program. The board is about an inch thick, contains an electrical grid underneath a hard Formica surface. The digitizer's pen or cursor (mouse-like device with magnifying glass and crosshair) creates a magnetic field which is "sensed" by the electrical grid in the board. Press the tip of the pen or push a button on the cursor and a highly accurate XY point, representing this location, is sent to the computer through a USB connection. The Logic Trace software then turns those points or stream of points into a DXF file. Most Jumbo Trace clients prefer using the pen stylus to trace around the edge of a part or pattern.

The standard accuracy of a digitizing tablet is .01" (10/1000). Divide an inch into 100 parts, the result is .01" accuracy. Larger digitizing tablets are also available in .005" (5/1000) accuracy, the higher accurcy adds $500 to the cost of the digitizer. Most clients that are working with cloth, foam, wood, or glass prefer the .01" accuracy. Clients working with metal use either the .01" or .005" accuracy.


  • Higher Accuracy - Upgrade the digitizer accuracy to .005"
  • Digitizer Stand - a pedestal under the digitizer with adjustable height and angle, $500. Some clients prefer to use a table or desk, mount on wall, or build a stand.
  • Extra Pen or Cursor - The digitizer comes with one corded or cordless cursor, extra pointers are available
  • LED Light Panel - A thin LED light panel that lays on top of the digitizing tablet that turns the digitizer into a surface lit digitizer. Fairly expensize and generally not needed for Tracing applications but useful for digitizing mylars, x-rays or other materials better seen with a back lighting.

Other Information

  • The digitizer can work in dusty environments including factories and shop warehouses
  • The digitizer can "sense" almost an inch above the surface allowing the digitizing designs on top of paper, cardboard, plastic, or plywood.
