Back with the release of SOLIDWORKS 2010, SOLIDWORKS introduced Global Variables. A nice little utility, to define a constant that can be used to drive multiple dimensions.
And for many situations this works well but the one downside is that a Global Variable has to be applied to each dimension individually. This can be tedious, when many dimensions need to be linked.
Prior to Global Variables, dimensions were made equal by using Link Values.
The main advantage of SOLIDWORKS Link Values, is that it can be applied to multiple dimensions at once.
How to Link Values
All that is required is selecting the dimensions that need to be linked, by using either Ctrl-select or Window select. After all the dimensions are selected, it’s simply a matter of right-clicking and selecting Link Values from the shortcut menu:
In the Shared Values dialog box, a Name is entered for the Linked Values.
Linked dimensions are denoted with a link (not infinity) icon.
Linking Values does require selecting all dimensions to be linked. In a situation where these dimensions may belong to different features, not all the dimensions will be visible. This can addressed by right-clicking on Annotations in The FeatureManager and selecting Show Feature Dimensions.
Modifying Linked Values
The Link icon will also appear in the Modify Dimension dialog box and modifying any one of the Linked dimension, will update all Linked dimensions
Linked dimensions can be unlinked by selecting one or more Linked dimensions, right-clicking and choosing Unlink Value.
