I always have the Offset Distance set to 10mm.   I am finding now as we are designing a larger range size of products, that the offset distance is being scalled along with the drawing.  Hence a large product leads to distances between dims to be very small.

It appears that SW2010 does not allow this scalling to be turned off!!!!

Hence im now looking into the API to see if this distance can be  updated ?

First attempt was to force the new offset into the document properties - but this does not refresh the drawing view.  All of our dimension lines are loaded from a document template and are not created at design time.

Ive found plenty of code to grab the dimensions values but cant see any refrence to its position and how to set it ?
