How to Move an Object a Specific Distance in Rhino

To move an object a specific distance in Rhino, you typically use the Move command or drag the object while typing the distance. Both methods allow you to precisely control how far your object travels in the 3D space.

Understanding how to move objects accurately is fundamental in Rhino for precise modeling and design. Rhino offers intuitive ways to achieve this, whether you're working with simple geometry or complex assemblies.

Method 1: Using the Move Command

The Move command is the most common and versatile way to move objects by a specific distance and direction.

Steps:

1. Select Objects: Choose the object(s) you want to move.
2. Activate Command: Type Move in the command prompt and press Enter, or select the Move icon from the toolbar.
3. Specify Base Point: Click in your viewport to set the starting point (or base point) for the move. This point does not have to be on the object itself; it's just a reference.
4. Specify Second Point or Distance:
   • To move to a specific location: Click a second point in the viewport. The object will move from the base point to this second point.
   • To move a specific distance in a specific direction:
     • Move your cursor in the desired direction.
     • Type the exact distance value at the command prompt (e.g., 10, 5.5).
     • Press Enter. The object will move the specified distance along the line defined by your base point and the cursor direction.

Practical Tips for the Move Command:

• Use Ortho: Press F8 or click "Ortho" in the status bar to constrain movement to horizontal and vertical directions relative to the current CPlane. This is useful for moving precisely along axes.
• Use SmartTrack: F11 or "SmartTrack" helps you align points and directions based on existing geometry, making it easier to define the move direction accurately.
• Use Object Snaps (Osnaps): Ensure appropriate Osnaps like "End," "Mid," "Cen," or "Perp" are enabled (F3 or status bar) to accurately pick the base point and define directions relative to other objects.

Method 2: Moving by Dragging with Distance Constraint

Rhino also allows you to initiate a drag move and then type a specific distance to control how far the object is dragged. This method is particularly quick for simple, directed moves.

Based on the reference "Move by Dragging":

1. Select Objects: Choose the object(s) or even sub-objects (like control points) you want to move.
2. Start Dragging: Click and hold the left mouse button on the selected object(s) and begin to drag them in the desired direction.
3. Type Distance: While still dragging (or immediately after releasing the drag), type the specific distance value you want to move the object at the command prompt.
4. Confirm: Press Enter. The object will jump to the location corresponding to dragging from its start point in the initial direction for the specified distance.

When to Use Which Method?

Feature	Move Command	Move by Dragging (with Distance)
Precision	High (precise base & end points)	High (precise distance)
Flexibility	High (defines start/end points)	Moderate (relies on initial drag direction)
Ease of Use	Requires clear point picking	Quick for simple linear moves
Control Points	Yes	Yes (via sub-object selection)

Both methods are effective for moving objects a specific distance. The Move command offers more control over the start and end points, while the "Move by Dragging" method can be faster for quick, directed movements where the initial drag direction is clear.
