Partial curvilinear length dimensions can be created using the
Dimensions and Length/Distance Dimensions commands;
they cannot be created using the Stacked Dimensions and
Cumulated Dimensions commands.
You can create partial curvilinear length dimensions for all types
of curves: splines, circles, arcs of circle, conics, etc. Note that
in the case of circles and arcs of circle, they will be called partial
circular length dimensions.
You can create partial length dimensions for lines.
The Dimension Parameters is defined by the administrator in the standards.
The same symbol is used for partial curvilinear dimensions and for curvilinear
dimensions.
Partial curvilinear length dimensions cannot be True Length dimensions.
If you delete a point that defines a dimension, the dimension becomes
not-up-to-date, and its color changes to fuchsia by default (or according
to the color defined for Not-up-to-date dimensions in the
Types and colors of dimensions dialog box available via
Tools > Options > Mechanical > Drafting > Dimension
tab, Analysis Display Mode area, Types and colors...
button). If you delete both points, the dimension becomes a regular
curvilinear dimension.
Important:
You cannot change the dimension line representation mode or orientation
after the dimension has been created.
In the case of the parallel and offset representation modes, the
dimension value cannot be moved out of the curve limits, except for
circles and arcs of circle. As a result, you cannot specify the dimension
value position (Inside, Outside, Auto).
In some cases, depending on the curve and on the offset value, the
offset representation mode cannot be computed.
In the case of partial curvilinear length dimensions in offset mode,
it is recommended to activate the Constant offset between dimension
line and geometry setting in Tools > Options > Mechanical > Drafting > Dimension tab. This will ensure that the dimension
remains associative if the geometry is moved.
Partial curvilinear dimensions cannot be measured along a direction.
However, partial length dimensions can be measured along a direction.
Partial curvilinear dimensions cannot be driving dimensions.
When creating partial circular length dimensions on circles, you
cannot select a circular sector.
