A leaf element is a sub-element that does not have any further sub-elements.

While measuring the geometries of a leaf element, irrespective of the selected filter, the behavior of the measure commands before and at the time of selection of the feature is as follows:

Pre-Selection Behavior

If the simplified geometry of an element is not loaded, when you hover over the element for some time, the respective simplified geometry is loaded. You can highlight or select the required geometry based on the selected filter. Once the simplified geometry representation of an element is loaded, it is kept while the measure command is active.

After the measurement is created, the simplified geometry representation can be unloaded and replaced by the 3D thumbnail, if required.

Selection Behavior

Whenever a selection is done with pre-selection not lasting for enough time or no pre-selection at all (in the case of touch interfaces), the respective simplified geometry is loaded.

After the simplified geometry representation is loaded:

  • If the selected geometry does not correspond to the selected filter:
    • If the Point filter is selected, the measure is created for the selected point.
    • If any other filter is selected, the measurement is not created and you must select a geometry corresponding to the selected filter.
  • After the selected geometry is loaded, the simplified geometry representation is kept until the measure operation is in process.

If the simplified geometry representation of the selected element cannot be loaded:

  • If the selected element is loaded but its simplified geometry representation is not loaded, the 3D thumbnail representation is considered and the measurement is created.
  • If the selected geometry corresponds to the selected filter, a measurement is created.
  • If the selected geometry does not correspond to the selected filter:
    • If the Point filter is selected, the measure is created for the selected point.
    • If any other filter is selected, the selected element is ignored and a warning is displayed.

When the product filter is selected and the measurement is computed, a level selector highlighting the selected product level is displayed. If the selected product is fully loaded, the measurement is updated according to the new level.

If the selected product is not fully loaded, the measurement is not updated and is displayed with less opacity.

The level selector is updated according to the new selected element.

Object-Action mode

This section explains how to create measures by selecting the elements before selecting the command.

  • If you select the elements to measure before the command, the selected elements determine the measurement type. The measure selection filters are not available.
  • The simplified geometry representation of the selected elements must be loaded. Only the elements for which the simplified geometry representation is loaded are taken into account when creating measurements for pre-selected elements. If the simplified geometry representation is not loaded, such elements are deselected.
  • If just one element is selected, the measurement is created accordingly.
  • The following applies for multi-selected elements:
    • If two elements are selected, the measure between result is created.
    • If three points are selected, the angle by three points measure is created.
    • If more than three elements (say N elements) are selected, N-1 chained measure between results are created.
      Note: In this case, if an arc or circle, or the cylinder or cone geometries are selected, then the center points or axes are taken into account for the measure.
  • You can control whether or not the 3D geometries inside a 3D part or a 3D representation and the 2D geometries from a view can be selected. .
