Measuring Geometry Objects and Entities
There are different ways of measuring geometry objects and entities, depending on how the measurement will be used. If you want to quickly check coordinates, distance, area, or volume in a geometry, you can Measure Using Messages Window or use the Measure Window. If the measured value will be used later in the Geometry sequence or when setting up the physics, use the Measurement Parameters (3D, 2D, and 1D) or, if you are already using constraints and dimensions, available with the Design Module, use the Dimension Parameters in Sketch (2D).
Measure Using Messages Window
To measure a set of geometric objects or entities selected in the Graphics window, click the Measure button () in the Geometry toolbar (this button is also available in the Mesh toolbar) or right-click in the Graphics window and choose Measure () from the context menu.
The result appears in The Messages Window:
Most measured quantities are approximate because they are based on approximating the geometry with a triangular or polygonal mesh (corresponding to a rendering mesh with the graphics rendering Detail set to Fine). The number of digits displayed (all of which are not necessarily accurate) is controlled by the Output display precision field on the User Interface > Precision page in the Preferences window. However, for straight edges and for the coordinates of and distances between vertices, at least 10 digits are displayed, and they are all accurate.
Measure Window
Another way to measure geometry objects and entities is to right-click the Geometry node and select Measure () from the context menu. This opens the Measure window, where you can, for example, measure the volume, area, or length of a selected domain, face, or edge. You can also view the coordinates of a vertex, the distance between two vertices, or the number of entities and the geometry representation (requires a license for the CAD Import Module) of an object. The Measure window has the following content:
Geometry Type
From the Type of geometry list, select to measure geometry objects (the default) or the finalized geometry.
Selection
From the Geometric entity level list, select Object, Domain, Boundary, Edge, or Point. Then select some objects or entities of the selected type to add to the list.
Measurements
Under Measurements you find information about these objects, entities, or finite voids. For objects, this section contains the total number of domains, boundaries, edges, points, and finite voids, and the geometry representation. For domains, boundaries, and edges, their total volume, surface area of 3D domains, area of selected boundaries, or length appears. For faces in 3D and domains in 2D, the perimeter is also displayed. If you select a point (vertex), its coordinates are shown. If you select two points (vertices), the distance is shown. If you select two or more points, the average coordinates for the selected points are shown. In all cases except for a single point, maximum and minimum values of the bounding box are also shown.
You can add a Mass Properties node to define variables for mass properties such as the total volume, total mass, and the center of mass.
Measurement Parameters
Use the measurement parameters to create parameters that measure a position or distances in 3D, 2D, or 1D geometries based on a selection of entities. These parameters can be used later in the Geometry sequence or when setting up the physics.
The following conditions apply when using measurement parameters:
The Condition expression in If and Else If features does not support measurement parameters.
You can use measurement parameters created in a component in features under a Study, Results, and Global Definitions > Materials nodes.
Dimension Parameters in Sketch
For 2D and plane geometries, use the dimension parameters available with the Constraint and Dimension Features to create parameters that measure a position, length, distance, radius, or an angle based on a selection of entities. These parameters can be used later in the Geometry sequence or when setting up the physics. For details, see the section Dimension Parameters.
It is not possible to add Measurement Parameters to the geometry sequence when the use of Constraints and Dimensions is enabled.
