I am wanting to make a model easier to work with therefore I added global variables to describe my model. 

However I am unable to update the dimension which use the global variables in the model. 

My variables are Length, Height, Depth and were defined in during the sketching process (depth when extruding). 

The variables were then exported and linked to a text file. 

Text file was modified with new values and saved. 

Model was rebuilt. 

Under Equations new values are seen however the model hasn't changed.

Sketch is opened old variable is still there. 

Dimension is double clicked, dimension updates to new variable and model is the correct size.

How do I update all the dimensions at the same time?

Thank you.
