More About the Measure Item Dialog Box

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:

  1. 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 on-the-fly and are therefore not persistent nor associative and cannot be used as parameters.

    • Create Geometry button: lets you create the points and line corresponding to the minimum distance result.

    • Customize... button: lets you customize display of measure results.

    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.

      P1-Only Functionality

      In P1, the Measure Tools toolbar appears. 

      This toolbar has two icons:

      • Measure Dialogs : lets you show or hide the associated dialog box.

      • Exit Measure : lets you exit the measure. This is useful when the dialog box is hidden.

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.

  • Thickness (DMU only): measures the thickness of an item. For more information, see the appropriate task in the DMU Space Analysis User's Guide.

The Measure Item command:

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

  • recognizes ellipse-type 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).
