Modify the properties of existing dimensions
While you can use the tool settings to define the properties of the future dimensions that you'll plot, you can change the properties of existing dimensions only from the Properties panel. For this, you just have to select the dimension objects and go to the Properties panel. You can then apply these new properties to the dimension objects that you've selected or apply them to all the existing dimension objects by selecting Apply to all. Additionally, you can select Set as default to change the settings for all the existing and future dimensions.
Furthermore, if you transform the objects, the associated dimensions adjust automatically. For example, if you increase the width of a rectangle, the dimension object that measures the width will update automatically to reflect the new measurement.
