We are detailing waste pipe for a large high rise, we send out trimble points to the field to locate sleeve points in the slab, along with this they need a .DWG. So we export a .DWG from a plan view, when you open the DWG in Autocad a lot of the 90's and couplings have shifted. In the revit model everything is still in the right place though. Is there an export setting that might be shifting these parts?
