Select object basics

To select single objects with a click

To select objects by a window rectangle

Note

See: SelWindow

To select objects by a crossing rectangle

See: SelCrossing

Note

To add objects to a selection

To remove objects from a selection

Selection menu

If several objects appear to be stacked in the area of the cursor and Rhino is not able to tell which one you want to select, the Selection Menu appears.

When the Selection Menu pops up, the current object and its designation in the list highlight.

To select an object

  1. Use the mouse wheel to cycle through the list.
  2. Click the right mouse button to accept the currently-highlighted object name.

To cancel the selection process

To configure the selection menu, see: Selection Menu Options, or right-click the Selection Menu title bar.

Select sub-parts of objects

For many commands, you can select sub-parts of objects or specified object types to allow you to restrict selection in a tight area.

Examples include:

Selecting sub-objects with a mouse

You can select sub-objects with a mouse before a command starts (pre-select) or during a command (post-select).

To select sub-object parts with a mouse

To de-select sub object parts with a mouse

Restrictions for blocks:

Select sub-parts with a command-line filter

Command-line selection filters work on a more limited set of sub-objects for commands that ask you to select objects after the command starts (post-select). These commands let you use filters to pick a sub-part of an object or specific objects rather than the whole object.

To select a sub-part of an object as input to a command, type

Sub-object parts can be selected and de-selected using capture tools: SelWindow and SelCrossing, Lasso, SelBrush, SelCircular, SelBoundary, SelVolumeSphere, and SelBox.

SelectionFilter

Selection Filter

Filter

The SelectionFilter command opens the Selection Filter control. The Selection Filter restricts any selection mode (SelWindow, SelCrossing, SelAll, etc.) to specified object types.

Selection Filter options

Disable

Turns off selection filters.

Checking all checkboxes also turns off selection filters.

Sub-objects
When enabled
Points (Points/Vertices)

Restricts the selection to point objects, and with the Sub-objects checked, polysurface/mesh vertices.

Polysurfaces

Restricts selection to polysurface objects.

Lights

Restricts selection to light objects.

Point clouds

Restricts selection to point cloud objects.

Curves (Curves/Edges)

Restricts the selection to curve objects, and with the Sub-objects checked, sub-curves and polysurface/mesh edges.

Meshes

Restricts the selection to mesh objects.

Blocks

Restricts selection to block instances.

Hatches

Restricts selection to hatch objects.

Surfaces (Surfaces/Faces)

Restricts selection to surface objects, and with the Sub-objects checked, polysurface/mesh faces.

Annotations

Restricts the selection to Dimensions, Leaders, Dots, and Text.

Control points

Restricts the selection to curve and surface control points.

Others

Control cages

Morph control objects

Detail views

Clipping plane objects

Note

Example: To select only red points

  1. Set the filter to Points.
  2. Use the SelColor command to select red objects.
    Only red points will be selected.

Example: To select only curves within a window

  1. Set the filter to Curves.
  2. Window select objects.
    Only curves within the window will be selected.

Example: To select curves one time

  1. Set the filter to Surfaces.
  2. With the mouse over the Selection Filter control press Ctrl or Shift.

  3. Click Curves.
  4. Select objects.
    Only curves will be selected for one selection. The filter then returns to its previous mode.

To clear all but one filter

To restore the previous set of filters

To clear / restore all filters

One-shot selection filters

You can restrict selection to one or more of the filtered types for one selection only. For example, this lets you select only curves or only hatches and blocks for the next single click, window, crossing or any other selection operation.

To restrict the object type for one selection only

  1. Press Ctrl and hover over the Selection Filter control.

    The check boxes clear and change to buttons.

  2. Click the buttons for the object types you want to select.

Pre-select/Post-select

For commands requiring selected objects as input, the objects can be selected before starting the command or after starting the command. Normally pre-selecting objects saves steps; however, in some cases the prompts and options for the command may be slightly different depending on the order used. When objects are pre-selected the possibilities include:

Boundary

The SelBoundary command selects objects based on a boundary defined by an existing closed curve.

Command-line options

Precise

Yes

The selection wire boundary is used as the boundary.

The testing is done in double-precision floating point in screen space. If any part of the object is even slightly outside the selection boundary, it will not be included.

No

A selection mask bitmap is built from the boundary, and the objects are tested against that mask.

The testing is done using a bitmap selection mask, which effectively adds an average of half a pixel wide fuzz zone around the selection boundary. Objects that visually seem as though they should be included, but are actually partially outside the boundary, are still included.
