Selection window (only Preprocessing)

Menu: Utilities->Tools->Selection window...
Mouse menu: Contextual->Selection window

For those functions where some entities are to be selected (creation of a surface or a volume, copying entities, etc.), it is possible to use the Selection window. The selection window lets you take control of the selection process.

Note: The selection window option is only available in the mouse menu during the selection process.

The selection window has the following options:

• Select all: If this option is chosen all entities are selected. If a filter is selected, it is applied to all entities.

• From, To: This option lets you select a range of entities. If a filter is selected, it is only applied to that range of entities. To see the ID numbers of entities, use the Label command (see Label).

• Mode: There are three selection modes:

  • Swap : If you select an entity that is already selected, the entity is deselected, and vice versa.

  • Add : In this mode it is impossible to deselect an entity. Only new entities are added to the current selection.

  • Remove : In this mode it is impossible to add entities to the selection. This mode is used to remove entities from the current selection.

• Filter: If a filter is selected, only the entities that satisfy the filter criteria will be selected. This menu changes depending on what type of entity is being selected:

  • Points

    • Higher entities: You are asked for a value, and all points with this Higher Entity number are selected (Higher Entity number is the number of lines that a point belongs to).

    • Layer: select entities that belong to this layer.

    • Group: select entities assigned to this group.

    • Label: Selects all points where a Label is shown or not (On or Off).

    • Material: All points with a chosen material assigned are selected.

    • Condition: All points with a chosen condition assigned are selected.

  • Lines

    • Higher entities: You are asked for a value, and all lines with this Higher Entity number are selected (Higher Entity number is the number of surfaces that a line belongs to).

    • Layer: select entities that belong to this layer.

    • Group: select entities assigned to this group.

    • Label: Selects all lines where a Label is shown or not (On or Off).

    • Material: All lines with a chosen material assigned are selected.

    • Condition: All lines with a chosen condition assigned are selected.

    • Min. length: Selects only the lines whose length is greater than the given length.

    • Max. length: Selects only the lines whose length is smaller than the given length.

    • Entity type: Selects only the lines which fit the specified type: StLine (Straight Line), ArcLine, PolyLine or NurbLine.

  • Surfaces

    • Higher entities: You are asked for a value, and all surfaces with this Higher Entity number are selected (Higher Entity number is the number of volumes that a surface belongs to).

    • Layer: select entities that belong to this layer.

    • Group: select entities assigned to this group.

    • Label: Selects all surfaces where a Label is shown or not (On or Off).

    • Material: All surfaces with a chosen material assigned are selected.

    • Condition: All surfaces with a chosen condition assigned are selected.

    • Num. sides: All surfaces with a chosen number of sides are selected.

    • Entity type: Type of surface.

  • Volumes

    • Layer: select entities that belong to this layer.

    • Group: select entities assigned to this group.

    • Label: Selects all volumes where a Label is shown or not (On or Off).

    • Material: All volumes with a chosen material assigned are selected.

    • Condition: All volumes with a chosen condition assigned are selected.

    • Num. sides: All volumes with a chosen number of sides are selected.

    • Entity type: Type of volume.

  • Nodes

    • Layer: select entities that belong to this layer.

    • Group: select entities assigned to this group.

    • Label: Selects all nodes where a Label is shown or not (On or Off).

    • Condition: All nodes with a chosen condition assigned are selected.
