Scale sketch entities and keep relations

Greetings All:


I have a fairly complex feature pattern that needs to be chrome deposited onto glass.  The design of this pattern has been given to me in units totally arbitrary to the part.  To get the features done correctly on the part I have done several different things.

1. Draw the complex pattern in the original units, scale the pattern with known scale factor, then fix the final geometry so it cannot be adjusted.  This option works, but allows no flexibility if we want to make simple changes.  If we change the original pattern, the scaled pattern is not linked.  If we make changes to the scaled pattern we have to calculate the designered change in part units based on scale factor.

2. We draw the complex pattern only once and use global variable scale factor x the original unit to dimension everything.  This has a lot of flexibility, but is very time consuming and if you want to make sure everything is done correctly, you have to go into each dimension to see the math. 


Is there a way to scale a sketch entity with a given scale factor, and have the two entities linked?  I think of patterning sketch entities where you can change the number of patterns by changing a "dimension".
