this helps - at least I now know to ask people to send their AutoCads to me in DXF-format. I don't have AutoCad, so I can't convert DWGs to DFFs myself.
Would you or someone else also happen to know how to change the scale in a DWG that is imported to TAB? Apparently the DWG is drawn in millimetres and MapInfo seems to think they are metres. So, I get doorways that are 2 700 metres wide when they actually should be 2,7 metres etc.
Than you,

Normal DWG files do not contain a projection. Generally they are drawn to scale, normal engineering drawings are likely to be in metres, millimetres, feet or inches.
One way of turning a multi-layer DWG file into a single TAB is to first convert it to a DXF , then use MapInfo's Table > Import function to convert that.
Hope this helps.

Re: [MI-L] DXF & DWG Import - Maintaining Layers & Minimizing Warp
Hi,
this seems to be an old topic, but perhaps someone notices the message now... I too would appreciate help with DWG imports. Frank pretty much summed up all my problems too.
Best regards,

Hi All,Does anyone know of a way to maintain a DWG file so that it does not devolve into all of the miscellaneous layers when importing through MI 8's UT? Additionally, does a way exist to determine the projection that the drawing may have been saved when it was created with AutoCad? I do not have access to AutoCad but can use a viewer - did not know if any viewers allow for the determination of the file's projection if it does exist. If a projection was not associated with the DWG - what projection is recommended to use with a set of Geocoded Data (i.e., Radio Measurements collected with a Garmin GPS that was set to Long/Lat: WGS84) that will be overlaid on the map. I want to minimize the warping of the DWG file. Best regards,
