Hi, Starting a project (work in Archicad) with another group who work in Vectorworks. All the drawing will be in 2D and shared by converting to dwg's. Two potential issues are: Origins Layers/Classes The plan is to start with one set of plans say drawn on vectorworks and then converted to dwg's which will be shared with us who can then make alterations to send back, or receive updated files which we can import. Is there a way of ensuring the origin is the same so we don't have to line up drawings using chimneys or the like. Secondly at the vectorworks end is there a guide or reference document to explain how to set up the vectorworks export dwg tool in such a way as the classes and layers are combined and information not lost between converting and then reimporting. For example is it possible to export a file in VW to a dwg, and then import that dwg to VW and have an identical file without any loss of class/layer data? I note a mapping option in the export menu and suspect this may be of use. We are having a meeting tomorrow and hope to agree on a protocol which we will all use. Thanks for any info in advance.
