What Is Jogged Dimension in AutoCAD?

Understanding Jogged Dimensions in AutoCAD

Jogged dimensions are a specialized feature in AutoCAD used to indicate measurements with complex geometries that require a clear understanding of spatial relationships. This type of dimension allows a dimension line to "jog" or bend to fit precisely alongside other elements of your drawing, ensuring readability and clarity without overlapping other components.

What Is a Jogged Dimension?

A jogged dimension is essentially a linear dimension that has an adjustment point—referred to as a jog—that helps to define a measurement distinctly where space is limited or where potential conflict with other drawing elements exists. This helps to maintain a clean layout by avoiding confusion that may arise from straight dimension lines overlapping with other components of the design.

How to Draw a Jogged Dimension in AutoCAD

Drawing a jogged dimension in AutoCAD involves a few simple steps. Here’s how to do it:

  1. Initiate the Command:

    • Start by typing DIMJOGGED into the command line and press Enter. This activates the jogged dimension tool.
  2. Select First Point:

    • Specify the first extension point of your dimension line. You can either click on the desired point in the workspace or enter its coordinates manually.
  3. Define the Jog Point:

    • Click on the point where you want the jog to occur. This jog point will serve as the bend in the dimension to avoid other elements.
  4. Specify Second Point:

    • Indicate the second extension point, which helps to finalize the dimension measurement. Click on this point or enter its coordinates.
  5. Finish Dimensioning:
    • Review and place the dimension line in the best position for clarity. Move your cursor to adjust the dimension line’s final position if necessary, and click to place it.

Associating Dimensions in AutoCAD

Associative dimensions in AutoCAD are smart measurements that automatically adjust if the geometry to which they are linked is modified. Here’s how to set these up:

  1. Navigate to the Annotate tab and select the Dimensions panel.
  2. Click on Reassociate.
  3. Choose the dimensions you wish to associate or reassociate.
  4. Press Enter. You can then choose to associate the dimension to a specific object by pressing ‘s’ and selecting the desired geometry. Repeat as necessary to associate other dimensions.

Types of Dimensions in AutoCAD

AutoCAD categorizes dimensions mainly into two types: size dimensions and location dimensions. Size dimensions measure physical sizes such as lengths and widths, while location dimensions establish the position of elements relative to each other.

Creating Annotative Dimensions

To enhance the clarity of dimensions across various scales, AutoCAD allows you to create annotative dimensions. Follow these steps:

  1. Insert your dimension or text as required.
  2. Open the Properties palette and set the Annotative option to Yes.
  3. Access the Annotative Object Scale dialog to adjust and set the necessary scales for your dimensions.
  4. Confirm your changes by clicking OK.

FAQ

1. What are the benefits of using jogged dimensions?
Jogged dimensions improve the clarity of your drawing by preventing dimension lines from overlapping with other elements. This makes your plans easier to read and reduces potential confusion during interpretation.

2. Is it possible to convert regular dimensions into jogged dimensions?
You cannot directly convert a regular dimension into a jogged dimension, but you can delete the original dimension and recreate it using the jogged dimension command for specific scenarios.

3. Can jogged dimensions be associative?
Yes, jogged dimensions can be associative. They can automatically update if the associated geometry changes, maintaining accuracy and integrity within your design.
