This key provides a link to give location data such as floor area and also provides the way of linking other information onto a floor plan within Micad. <BR /> <BR /> There is no alternative way to transfer relevant drawn information into Micad. <BR /> <BR /> We have moved the office to ArchiCAD but there is no equivalent to the autocad handle that we can use to create this link with Micad. <BR /> <BR /> We have therefore looked at saving ArchiCAD files as dwg files (and using the handles that are generated by this process) but we have found that if we subsequently amend a drawing and then re-save it as a dwg, the handles are re-generated and we lose consistency. It's equivalent to a room that is given a handle of LB45 being given a handle of XC889 when we re-save it as a dwg. This breaks the link to the Micad data. <BR /> <BR /> Does anyone have any advice about how we could maintain the 'handle' consistency? <BR /> <BR /> Many thanks.</T></DIV> Mon, 17 Oct 2016 20:45:40 GMT Anonymous 2016-10-17T20:45:40Z https://community.graphisoft.com/t5/Collaboration-with-other/Autocad-handles/m-p/237208#M30472 <DIV class="actalk-migrated-content"><T>We have, for a number of years, been importing drawn information into a Micad FM database using autocad's 'handles' as the key.
