When placing a copper tube, say from the autodesk library (Pipe-B88-CU-L(PE)), then stretching the pipe, doing a fill, anything I will get the waringing "Dimension B is Invalid (0.4375)".  The warning has the heading Pattern: - 1/4 and I have to click ok through the entire product list.  This can happen with only placing pipe on its own and trying to stretch it.  I have had this problem with earlier versions where I'd turn off the insulation.  Not the case in this instance.  All insualation and insulation specs are off and not set.  I am using CADmep 2016 SP-1 and AutoCAD MEP 2016 with the hotfix's installed.  I've tried a new drawing and still get the same occurance.

Is anyone else having this problem?  If so, is there a fix other than getting rid of product lists and calc the same pipe size?
