Selection commands
Dedicated selection commands let you select by object properties.
Selection categories
Select object basics
To select single objects with a click
- Click an object to select it.
- Click away from the objects to deselect.
To select objects by a window rectangle
- Drag a selection rectangle from left to right to use a window selection.
Note
-
When you make a window selection, objects completely enclosed in the selection rectangle are selected.
-
To make the mouse always use either a window or crossing selection, see Mouse Options, Mouse group select.
-
Search for SelectionWindowStrokeColor and SelectionWindowFillColor in Tools > Options > Advanced to change the colors of the window selection rectangle.
See: SelWindow
To select objects by a crossing rectangle
- Drag a selection rectangle from right to left to do a crossing selection.
See: SelCrossing
Note
-
When you make a crossing selection, all objects inside or partially inside the selection rectangle are selected.
-
To make the mouse always use either a window or crossing selection, see Mouse Options, Mouse group select.
-
Search for SelectionWindowCrossingStrokeColor and SelectionWindowCrossingFillColor in Tools > Options > Advanced to change the colors of the crossing selection rectangle.
To add objects to a selection
-
Press and hold Shift while clicking single objects or using a window or crossing.
Shift + or
To remove objects from a selection
-
Press and hold Ctrl(CMD) while clicking single objects or using a window or crossing.
Ctrl(CMD) + or
-
When two shaded objects, one behind the other, are selected, Ctrl(CMD)+clicking on the wireframe of the object behind, it gets deselected, not the object in front.
-
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
- Click the desired object name in the selection menu list with the left mouse button.
Or - Click the left mouse button at the original pick point to cycle through the object name list.
- Click the right mouse button to accept the currently-highlighted object name.
Or
- Use the mouse wheel to cycle through the list.
- Click the right mouse button to accept the currently-highlighted object name.
To cancel the selection process
- Click None.
- Click away from the objects.
- Click another object.
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:
- Curve and surface control points
- Polysurface and extrusion faces and edge curves
- Surface edge curves
- Mesh vertices, faces, boundaries, and edges
- SubD surface points, faces, boundaries and edges.
- Objects and sub-objects within a group
- Polycurve and polyline segments
- Surface, polysurfaces, and extrusion object vertices. These are the equivalent of the points enabled by SolidPtOn.
- Whole objects in block instances.
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
-
Press and hold Ctrl(CMD) + Shift and left mouse click, window, or crossing.
Ctrl(CMD) + Shift + or
To de-select sub object parts with a mouse
-
Press and hold Ctrl(CMD) and left mouse click, window, or crossing.
Ctrl(CMD) + Or
Restrictions for blocks:
- Only whole objects in blocks can be selected.
For example, you can select a box in a block, but you cannot select its faces or edges. - Whole objects and sub-objects in nested blocks cannot be selected.
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.
Pre-select/Post-select
For commands that require object input, the objects can be selected before or after the command starts. Command prompts or options may be slightly different in the two methods. When objects are pre-selected the possibilities include:
- The command determines that the objects can be used and proceeds without further prompting.
- The command may proceed, but the result may be unexpected.
- The command cannot determine which objects are to be used and the pre-selected objects are unselected, and you are prompted to select specific objects again.
- Options may not appear at the command prompt.

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.
