https://forums.autodesk.com/t5/dynamic-blocks-forum/3d-dynamic-block/m-p/7816944#M27316 <P>I am using CADmep fabrication for HVAC. I often have to create HVAC units and VAV boxes. At times I have to create 30 or more of them for one job because they are slightly different, such as in length and where the supply and return are. I am a revit person now working in cad and I was hoping to create something akin to families in revit. Its proving much harder than I thought. I attached a chiller I have created that I am trying to use stretch parameters on.</P><P>I have the stretch parameter set up and I can move it, problem is, it just moves, it wont stretch.&nbsp;</P> Wed, 28 Feb 2018 18:07:00 GMT Anonymous 2018-02-28T18:07:00Z
