How to edite Dimensions

Free tutorial how to edite Dimensions in AutoCAD

There are many ways to edit existing dimensions & the method you choose will depend on the type of change & number of dimensions.
You can use Stretch on dimensions and the dimension text will update automatically (unless you replaced <> with text).

You can also use grip editing techniques to stretch grips of dimension objects for various different effects.

select a dimension if no command is running to display grips.
left-click on a grip to make it hot and then pick a new point to stretch that grip.

You have already seen how you can create an Override and then Update selected dimensions to change how dimensions appear.

you can use overrides for the next few (new) dimensions you create if they must be slightly different than the current style.
but the Override/Update approach can be awkward for making minor changes to a few existing dimensions.

You can make common changes to existing dimensions using a shortcut menu instead of using the Override/Update approach.

select the dimension(s) that you want to change when no other command is running to highlight those dimensions
then right-click to invoke a shortcut menu and select the desired option to change the selected dimension(s).

Using the Override/Update approach to change dimensions is NOT practical for quick changes to existing dimensions.

Editing dimensions using the shortcut menu is practical but you cannot change all dimension variables (properties) with a shortcut.

The Properties command lets you modify all dimension variables in an efficient interface (with only slightly more effort than a shortcut).

select dimensions that you want to change when no command is running to display their properties in the Properties list.
you can also use the Quick Select tool to help you select the desired dimensions automatically if you wish.

You can select as many objects as you wish and the total number of selected objects is listed in the Properties drop-down list.

you can then restrict edits to specific object types by selecting the desired object types in the Properties drop-down list.

The categories for dimensions correspond to the tabs in the Dimstyle dialogue box

and you can use the Misc category to change the dimension style of selected dimensions.

Close the drawing from the previous exercise if it is open.
Open the T112_12.dwg drawing in your personal folder.
Zoom In for a closer view of the large (current) viewport.
Select the dimension near P1 when no command is running to display the grips. Pick the grip near P1 to make it hot & pick near P2 to stretch this dimension to a new location.
