In certain instances of dimensions defined with the CADAM Drafting
product, there is not a logical mapping to a supported dimension in the
Interactive Drafting product. In these cases, the dimension is
automatically exploded to geometry and text. The specific cases are listed
in the mapping table below.
The following table outlines the specific mappings for dimensions and
dimension properties:

CADAM standard dimensions
|
ANSI

Inherent
differences do exist between the "CADAM" standard and ANSI standard
dimensions. These dimensions are transferred to the ANSI standard, as
it is the closest standard supported with the Interactive Drafting
product. |
IBM standard dimensions
|
ISO Dimensions |
Inherent
differences do exist between the "IBM" standard and ISO standard
dimensions. These dimensions are transferred to the ISO standard as is
the closest standard supported with the Interactive Drafting product. |

Dimension -
non supported cases: |
|
|
Chamfer dimension
|
Exploded to
geometry and text (*) |
Chamfer
dimensions are not supported in the current release of the Interactive
Drafting product. Therefore, these dimensions are exploded into
geometry and text. |
Extension lines - broken, no-shown, or skewed
|
Exploded to
geometry and text (*) |
Dimensions
with modified extension lines are not supported in the current release
of the Interactive Drafting product. Therefore, these dimensions are
exploded into geometry and text. |
Parallel dimension to an arbitrary line
|
Exploded to
geometry and text (*) |
Linear
dimensions that do not measure horizontal , vertical or true distance
(the dimension line was created at a user defined angle) are not
supported by V5 and will be exploded. |
Text, non-standard text in dimension text string
|
Exploded to
geometry and text (*) |
Dimensions
with non-standard text (e.g., line feeds, substring box, subscripting)
are not supported in the current release of the Interactive Drafting
product. Therefore, these dimensions are exploded into geometry and
text. |
Dimension,
special cases: |
|
|
Dimensions in an alternate origin where the axis
scale does not equal the view scale.
|
Dimensions in an alternate
origin where the axis scale does not equal the view scale. |
Alternate origins are not
supported in V5. Dimensions are changed to out-of-scale to preserve the
dimension value in the original context but not present it as an
in-scale dimension. |
Diameter dimension (ANSI), two part dimension line
|
Diameter
dimension (ANSI), two part dimension line |
For diameter
dimensions with two part dimension lines, CADAM Drafting allows the
interior portion of the dimension line to be not shown. The Interactive
Drafting product supports the interior portion being not shown only
when an addition segment is drawn on the opposite side of the circle.
Therefore, the transferred dimension may not be visually identical. |
Dimension with leader
|
Dimension with
fixed leader position |
The current
version of the Interactive Drafting product does not allow explicit
placement of dimension leaders. Therefore, the dimension will be
transferred with a leader, but the position of the text and leader may
be visually different. In addition, text associated with a leader for
an ISO or JIS dimension in the CADAM Drafting product is displayed
parallel to dimension line. With the Interactive Drafting product, this
text is displayed horizontally. Therefore in this case, the leader and
text will display at a different angle after transfer. |
Radius dimension (ANSI), two part dimension line
|
Radius
dimension (ANSI), two part dimension line |
For radius
dimensions with two part dimension lines, the portion of the dimension
line on the interior of the arc is either not shown or drawn to the
center of the circular arc on CADAM Drafting. The Interactive Drafting
product allows the interior portion to be not shown, but it does not
allow it to be drawn to the center of the arc. Therefore, all
radius dimensions with two part dimension lines are transferred so the
interior portion of the dimension line is not shown. |
Dimension
properties: |
|
|
Dimension association to geometric element
|
Dimension
association to geometric element |
CADAM Drafting
supports both associative and non-associative dimensions. The current
release of Interactive Drafting only supports associative dimensions.
Given this difference, non-associative dimensions are still
transferred, but additional geometry is also created to satisfy the
association. The additional geometry that is created is not shown. |
Dimension line end conditions
|
Closest
possible end condition |
The current
version of the Interactive Drafting product does not support all end
conditions supported by CADAM Drafting. Therefore, end conditions will
be mapped to the closest possible supported end condition. |
Dimension text
|
Dimension
value text, before, after, upper, lower text |
The CADAM
Drafting product treats the entire dimension text is as one text
string. The Interactive Drafting product divides this into the
dimension value text, before, after, upper, and lower text. Therefore,
CADAM Drafting dimension text will be mapping to the appropriate
dimension subtext. As stated above in the special case section, the
dimension text elements in Interactive Drafting do not support all of
the text properties or capabilities of CADAM Drafting. If CADAM
Drafting dimension text is encountered that contains not supported
properties, the dimension is exploded to geometry and standard text. |
Dimension units
|
Closest
possible dimension units |
The current
version of the Interactive Drafting product only supports dimensioning
units of inches and millimeters. Therefore, dimensions using inch
dimensioning units will be transferred to inch dimensioning units. All
other dimensions will be transferred to millimeter dimensioning units. |
Extension line, gapping
|
Extension
line, blanking |
CADAM Drafting
supports extension line gapping values of standard, no gap, and
overlap. The interactive drafting product supports only positive values
for blanking. "Standard" and "no gap" will be mapping to appropriate
values of blanking. As overlap implies a negative blanking value, it
will be transferred as 0 blanking (equivalent to no gap). |
Extension line, overshoot
|
Extension
line, overrun |
The
interactive drafting product supports only positive overrun values.
Therefore, any CADAM Drafting overshoot value less than 0 will be
transferred as 0. |
Text location
|
Dimension
value location |
Because of
differences in text properties, as well as differences in the way CADAM
Drafting and CATIA V5 Interactive Drafting manage dimension text (see
"Dimension text," above), the text location may be different after
translation. |
Tolerance, basic
|
Dimension
value with text box frame |
CADAM Drafting
supports three different sizes of text box frames. Interactive Drafting
supports one text box frame. Therefore, the transferred text box frame
may not be visually identical. |
Tolerance, limit
|
Dual dimension
value |
|
Tolerance, single
|

|
Tolerance, standard tolerance
|
Tolerance,
numerical tolerance |
The display of
the tolerance information is slightly different between CADAM Drafting
and the Interactive Drafting product. For example, when you define an
upper and lower tolerance that are equal, both are displayed. For this
case, in the Interactive Drafting product, the tolerance value is
displayed only once, preceded by a plus-minus symbol. Upon transfer,
the closest possible tolerance display will be chosen. |
Tolerance, text height
|
Tolerance,
font size |
CADAM Drafting
allows you to create 1/2- or 3/4-size text for tolerance values. CATIA
V5 Interactive Drafting supports only full-size text, so all tolerance
values are displayed full size after translation. |
