When I try to open a dwg/idw file in draftsight that was generated in Autodesk Vault, there initially is no data visible. If I go to Insert / Block I see a lot of blocks and I can select each in turn and import them. Eventually I will get the complete drawing but of course all the blocks are on top of each other and they each need to be exploded to be able to work with them. Has anyone dealt with this situation and can offer some advice on this?
