This task will show you how to re-route dimensions, i.e. to recalculate
dimensions taking into account new geometry elements which are compatible
with the re-routed dimension type. |
 |
Re-routing dimensions can be particularly useful in the case of
isolated dimensions resulting from V4 to V5 migration. Indeed, re-routing
isolated dimensions to the geometry enables you make them associative. |
 |
Open the
Reroute_Dimensions.CATDrawing document. You can notice that the
dimension properties are customized. |
 |
-
Select Re-route Dimension
in the Dimensioning toolbar (Dimension Edition
sub-toolbar).
-
Select the angle dimension. You can notice that the
cursor indicates the type of dimension you are selecting.
-
Select the first element you want to take into account
for the dimension re-routing, and then the second element.
Select the first element. |
Then, select the second element. |
 |
 |
 |
During this operation, the cursor gives a graphic preview of what
type of element you are selecting (in this case, lines). |
A preview of the re-routed angle dimension is displayed.
-
Click to validate the dimension creation.
-
You can proceed in the same manner to re-route the other
dimension types available on the drawing.
|
 |
-
Always make sure that the element(s) to which you are
re-routing dimensions are compatible with the re-routed dimension
type. For example, when re-routing a radius dimension, you need to select
a curved element.
-
In a Generative Drafting context, you cannot re-route
dimensions generated via the Generate Dimensions command.
-
Re-routing dimensions preserves dimension properties when
you customized them.
-
When re-routing chamfer dimensions which have only two
reference elements (the element to be dimensioned and a single reference
line or surface), you will need to select three reference elements.
-
When re-routing a dimension from one circle to another,
note that:
A dimension associated to the circle's... |
will always be re-routed to the other circle's... |
and cannot be re-routed to the other circle's... |
