How to Join Explode Dimension in AutoCAD?

Understanding Dimension Handling in AutoCAD

Managing dimensions in AutoCAD can become complex, especially when dealing with exploded dimensions. To effectively join these dimensions, it’s essential to understand the underlying processes in AutoCAD.

Exploding Dimensions

Once dimensions are exploded in AutoCAD, there is no option to "fix" them. Instead, users must delete the exploded dimensions and recreate them from scratch to restore desired functionality.

Joining Dimensions

To join dimensions after they have been exploded, follow these steps:

1. Check Dimension Style: Before making adjustments, ensure that you are using the correct dimension style. You can do this by selecting the dimension or checking in the Dimension Style Manager accessible from the Home tab.

2. Recreate Dimensions:

   • Use the dimensioning tools available in AutoCAD to create new dimensions. Click on the dimension type you need, such as linear, angular, or radial, from the Dimensions panel.
   • Place your new dimensions accurately along the drawing by selecting the points appropriately.
3. Set Adjustments:
   • To avoid spacing issues when joining dimensions, employ the “Adjust Space” command found in the Annotate tab. This command allows you to create uniform spacing, enhancing the visual alignment of dimensions.

Avoiding Future Issues with Dimensions

1. Maintain Proper Settings: Ensure that the DIMASO system variable is set appropriately. This variable controls various dimension settings and can be modified via the command line.

2. Exploding Options: To enable the ability to explode blocks, ensure that the “Allow Exploding” option is active in the Block Editor. If this option is not checked when creating blocks, those blocks cannot be exploded, making it impossible to join dimensions effectively later.

3. Troubleshooting Incorrect Dimensions: If dimensions appear incorrect, it may be due to changes in units or 3D elevation discrepancies. Verify the initial unit settings in the drawing and check object elevations through the Properties palette.

FAQ

1. Can I recover exploded dimensions in AutoCAD?
No, once dimensions are exploded, they cannot be recovered. You will need to erase the exploded dimensions and recreate them.

2. How do I set standard spacing between dimensions?
To standardize spacing, you can use the “Adjust Space” command available in the Annotate tab. This feature helps ensure uniform spacing for better visual clarity in your drawings.

3. Why are my blocks not exploding in AutoCAD?
Blocks may not explode if the “Allow Exploding” option was not selected during block creation. Review this setting in the Block Editor to enable future explosions.
