Video - Tracing Example



Trace an entire outline with the pen stylus or cursor in minutes


- The standard accuracy of the electronic board is 0.01 in (0.254mm) which is more than adequate for most applications.

- A higher accuracy board with 0.005 in (0.127mm) is also available.


Trace, save, calculate

Trace on Screen

Load a picture into the software, trace the outline using the computer mouse, and save a vector file or calculate numbers.

Runs on Windows, Mac, and Linux Computers

Also support for cellphones, ipads, tablets, external monitors


Software currently available in 15 languages

Video - Example using all the tracing methods


Tracing Tools - Pen and Cursor

Trace an outline using the sharp tip of the pen stylus or using a cursor with magnifying glass and cross-hair.

Tracing Methods

Trace designs using freehand draw, lines, arcs, curves, points, circles, and shapes

Freehand Drawing

Trace complicated shapes simply by tracing with the pen stylus or with the 16 button cursor.

Easy Smooth Curves

Trace smooth curves with a series of points and when done the software will create a smooth curve through the points.

Lines and Arcs

Define straight lines by tracing starting and ending points, define arcs with 3 points

Circles and Shapes

Trace circles using any 3 points on the circle or tracing the center point and diameter. Trace squares and rectangles by tracing any 3 corners.



Use your Cell Phone and Ipad

- Place the cell phone or ipad on the tracing board for easy access

- Move the software control window to the cell phone (or ipad) and push buttons to control the tracing

- Move the software display window to the ipad (or tablet) and watch the design while tracing

Cursor Buttons

Program the buttons on the cursor to be different software commands, Trace patterns without using the computer

Customize the Software

Change the software to meet your needs.


Edit a outline by simply retracing part of the outline


Add optional layer names, numbers, colors, and line thicknesses.

How a Tracing Board Works

The electronic board is a grid of wires going up and down and across with a hard formica surface. The pen stylus or cursor generates a magnetic field that is "sensed" by the board. Push a button on the pen or cursor or push down on the tip of the pen and a stream of accurate XY points are sent to the computer. The Logic Trace software then displays these points as a drawing or numbers.

The boards are made in the USA, are in stock, and ready to ship anywhere in the world.

Trace Through Materials

The tracing board can recognize the pen or cursor almost an inch (2 cm) above the board.

Portable Rollups

Portable rollup tracing boards are also available. The rollup cursor is more accurate than the pen stylus.

Jumbo Tracer

Connect multiple boards for tracing very large patterns. Connect two to eight boards together for tracing patterns anywhere from 5x8' to 8x24'


After assembling a Jumbo Tracer, the boards are calibrated by tracing several points across the boards.

Which Industries Needs One?

Glass, Countertop, Metal Fabrication, Upholstery, Furniture, Aeronautics, Van conversions, anyone needing a large pattern traced.

Editing Between Boards

Trace between boards, by defining alignment points, moving the pattern, realigning, and editing

Most people find the standard accuracy works fine for most applications.

For CNC and CAD appliactions we recommend the hardboard. For best results with the flexible rollup, we suggest using the cursor.

That's easy, there is only one - It does it all

A Few Optional Add-ons:

A Spare Pen Stylus

An Extra Cursor

A Stand
