4.3.3 Shape Information details
Body
Length (X)
Specify X-direction length of the part's body size.
Width (Y)
Specify Y-direction length of the part's body size.
Length Tolerance (X)
Specify the part's X-direction length tolerance.
Width Tolerance (Y)
Specify the part's Y-direction length tolerance.
Height
Specify the part's height.
Height Tolerance
Specify the part's height tolerance.
Color
For the NXT, this is used for vision processing of parts. Parts that are using the body
detection vision types must have the color specified as “White”.
The vision type that this setting must be “White” are: 60, 61, 62, 63, 65, 71, 74, 80, 153,
160, and 252.
Parts using these vision type that do not appear “white” in the images (the body is completly
black with no leads), cannot be vision processed using these vision types.
Lead
Pitch Tolerance
It is the tolerance allowed for the deviation from the pitch as a percentage of the lead pitch
length. If no setting is made here, processing is carried out using a default value of 30%.
Element Information
Set element related data. An element is a group of leads on the same side of a part which
have the same length, width, and pitch. As there may be several elements on a part,
numbers are assigned to the elements for identification purposes.
Double-click the data cell for this field and the [Element Information] dialog box displays.

Position X, Y
This expresses the X- and Y-coordinates from the center of the part to the point on the side
of the part that is central with the element. (Refer to the figure below)
Side
Specify the side on which the element is located. Side numbers should always be assigned
as shown in the above figure (at direction 0).
P_pattern
Specify how the leads appear to the vision processing system. Select the P Pattern from
the choices that matches the lead image.
Refer to section 4.5 "P_pattern Details" for details on settings for this item. The table below
lists the common P_pattern settings for the NXT.
