I'm having coordinates problems with VW2018. For example, if you set your user origin to a topographic survey Northings & Eastings grid, in order to use the stake tool lto locate coordinated setting out points, often the set origin randomly changes for no apparent reason, changing all the coordinates set out using the stake tool. Sometimes, if I've referenced in a Topo Survey, and perhaps re-open the drawing or update the reference, somehow the reference moves miles away from the set user origin point because the coordinates have miraculously changed. I'm continuously having to check the user origin coordinates prior to issuing drawings, to ensure nothing has randomly changed. It is very frustrating. Has anyone else experienced problem? And if so, is it something I've been inadvertently doing whilst using VW2018? Or is this a known problem that Vectorworks are addressing?
