How Do You Set the Distance Between Two Objects in AutoCAD?

To set a precise distance between two objects in AutoCAD, you'll primarily use commands that involve moving or creating objects relative to one another. Here's how to approach this, broken down into common scenarios:

Methods for Setting Distance Between Objects

Several AutoCAD features allow you to precisely control the distance between objects. These include using the MOVE command with relative coordinates, the OFFSET command, and specific object snap settings.

1. Using the MOVE Command with Relative Coordinates

This is a fundamental method for placing an object a specific distance from another.

• Command: MOVE

• Process:

  1. Initiate the MOVE command.
  2. Select the object you want to move.
  3. Specify a base point on the object. This is the point that will be used as a reference for the move.
  4. Enter the relative coordinates for the desired displacement. Relative coordinates are entered in the format @x,y (for 2D) or @x,y,z (for 3D), where x, y, and z are the distances you want to move the object along the X, Y, and Z axes, respectively, relative to the base point. For example, @5,0 will move the object 5 units along the X-axis and 0 units along the Y-axis.

• Example: To move a circle 10 units to the right of a line:

  1. Type MOVE and press Enter.
  2. Select the circle and press Enter.
  3. Specify the center of the circle as the base point.
  4. Type @10,0 and press Enter. The circle will now be exactly 10 units to the right of its original position (measured from its center).

2. Using the OFFSET Command

The OFFSET command is useful for creating parallel lines, concentric circles, or parallel curves at a specified distance.

• Command: OFFSET

• Process:

  1. Initiate the OFFSET command.
  2. Enter the desired offset distance.
  3. Select the object you want to offset.
  4. Specify the side on which to create the offset object by clicking a point on that side.

• Example: To create a line parallel to an existing line and 5 units away:

  1. Type OFFSET and press Enter.
  2. Type 5 and press Enter.
  3. Select the line you want to offset.
  4. Click on the side of the line where you want the new line to be placed.

3. Utilizing Object Snap (OSNAP) Settings and Temporary Tracking Points

Object snaps allow you to snap to precise locations on existing objects (endpoints, midpoints, centers, etc.). You can combine object snaps with temporary tracking points to create accurate distances.

• Process:
  1. Start a drawing command (e.g., LINE, CIRCLE).
  2. Use object snaps to select a point on an existing object as a starting point.
  3. To create a tracking point, hover over an object snap point (like an endpoint), then slowly move your cursor in the desired direction. A dashed tracking line will appear.
  4. Enter the desired distance along that tracking line and press Enter. AutoCAD will place the point at that distance from the snapped point.

4. Using Polar Tracking

Polar tracking helps you draw lines at specified angles. While not directly setting the distance between objects, it aids in drawing objects at particular angles and distances from a reference point.

• Process: Enable polar tracking (usually F10). Set the desired angle increment (e.g., 45 degrees). When drawing a line or moving an object, you'll see alignment paths at the specified angles, allowing for precise placement at specific distances along those angles. Enter the distance once the polar tracking line appears at the desired angle.

Summary

AutoCAD offers several ways to set distances between objects precisely. Choose the method that best suits your specific design requirements. The MOVE command with relative coordinates offers fundamental control, while the OFFSET command efficiently creates parallel objects. Object snaps and tracking further enhance precision. Experiment with these techniques to find the most efficient workflow for your needs.
