https://forums.autodesk.com/t5/autocad-forum/using-expression-to-add-amount-to-a-linear-dimension/m-p/5603420#M332072 Thanks Kent, shall test this out tomorrow. The reason for using it is; the company I work for does steel decking layouts. When the deck is on an angle it has to be cut on-site so we allow an extra 50mm for the cut.<BR /><BR />Would you say using an expression like this would be the simplest way to do this?<BR /><BR />Cheers Wed, 22 Apr 2015 16:42:24 GMT Anonymous 2015-04-22T16:42:24Z
