The following section aims at describing the measure between
dialog box in detail:
Accessing the Measure
item Dialog Box
To access the Measure Item dialog box:

Click Measure Item .
In DMU, you can also select Analyze > Measure Item from the
menu bar.
The Measure Item dialog box is displayed:
Dialog Box Options


Other Axis check box: when selected,
lets you measure distances and angles with respect to a
local V5 axis system.

Keep Measure check box: when selected,
lets you keep the current and subsequent measures as features.

This is useful if you want to keep the measures
as annotations for example.
Some measures kept as features are
associative and can be
used to valuate parameters or in formulas. 

Note that in the Drafting and Advanced Meshing
Tools workbenches, measures are done onthefly and are
therefore not persistent nor associative and cannot be used as
parameters.


Accessing other measure commands

The
Measure Between command is accessible from the Measure
Item dialog box. Simply click one of the Measure Between
icons in the Definition box to switch commands.

In DMU, the Measure Thickness command is
also accessible from the Measure Item dialog box. For more
information, see the appropriate task in the DMU Space
Analysis User's Guide.
P1Only Functionality
In P1, the Measure Tools toolbar appears.
This toolbar has two icons:


Defining the Selection 1 Mode

Any geometry (default mode): measures
the properties of the selected item (point, edge, surface or entire
product).

Point only: measures the properties of
points. Dynamic highlighting is limited to points.

Edge only: measures the properties of
edges. All types of edge are supported.

Surface only: measures the properties of
surfaces.
In the last three modes, dynamic highlighting is limited to points,
edges or surfaces depending on the mode selected, and is thus
simplified compared to the Any geometry mode.

Product only: measures the properties
products. Products can be specified by
selecting product geometry, for example
an edge or surface, in the geometry area or the specification tree.

Angle by 3 points:
measures the angle
between two lines themselves defined by three points.

To define lines:

Select three existing points in the geometry area
or in the specification tree. Note: You cannot select picking points. Smart selection is offered.
This means that a sphere or circle, for example, are seen as
points.
The resulting angle is always positive. It is
measured in a counterclockwise direction and depends on the order
in which points were selected as well as your viewpoint (the normal
to the plane is oriented towards you). You can drag the angle line to show the
complementary angle (360°
 the initial angle measured).
You can also obtain the complementary angle when
measuring the angle on arcs.
Note: The dialog box and knowledge
parameters are refreshed. The value of the complementary angle is
stored along with the measure.
The Measure Item command:

lets you access the radius of an exact cylinder or
sphere.

recognizes ellipsetype conic sections.

Using the Other Selection... command in the
contextual menu, you can access the axis of a cylinder as well as
the center of a sphere to, for example, measure between two
cylinder axes.
Defining the Calculation Mode

Exact else approximate (default mode):
measures access exact data and wherever possible true values are
given. If exact values cannot be measured, approximate values are
given (identified by a ~ sign).

Exact: measures
access exact data and true values are given. Note that you can only
select exact items in the geometry area or specification tree. In certain cases, in particular if products are selected, a warning
dialog box informs you that the exact measure could not be made.

Approximate: measures are made on
tessellated objects and approximate values are given (identified by
a ~ sign). In design mode, the canonical type of surfaces (plane,
cylinder, etc.) is not recognized.

Note: You can hide the
~ sign using the Tools > Options command (General
> Parameters and Measure > Measure Tools).
