3.1 .VIS file description
The .vis file is a text file used to create the inspection program.
CAD coordinates
⇒ .vis file ⇒ .tst file.
This chapter will guide you around the main functions of Vision 2007 to enable you to create a .vis file
containing all the data required to create a graphic representation of the board panel.
The .vis file can be created in 3 ways:
Manually, using any text editor software. You can also use MS Excel (processing by lines and col-
umns, important for importing CAD data), but you must save the file in text format.
Automatically, using converters installed beforehand according to the CAD format used: FABMas-
ter®, UNICAM®, CIRCUITCAM® and others.
Automatically, using ViTECHNOLOGY built in CAD converter: VIS file wizard (see § 3.2 .VIS file
builder, for description).
3.1.1 Structure of the .vis file
The .vis file contains all the CAD data and the information concerning panel arrangement.
The .vis file is divided into 5 dif-
ferent sections:
General description (A),
Panel information (B),
Board arrangement (C),
Data matrix, fiducial and skip (
D
),
CAD coordinates (E).
The graphic representation is a .tst file which has been generated from a .vis file.

USED_DIM
It is the dimension of the
panel useful zone, whether
single or multiple board,
containing all the compo-
nents to be inspected.
Example
3.1.2.3 Description mode of the panel boards
3 board shapes are used: rectangle, ellipse and polygon:
Rectangle and ellipse shapes are defined by a
width and a height.
Polygon shape is defined by a series of points.
USED_DIM must
always be less
than or equal to
PANEL_DIM.

The origin point (the first point) is the
start of the board drawing and its
rotation axis.
