Tianxiao- I am having a lot of problems with getting the synch to work correctly. The link will not recognize the TM file and will ask me to force sync it. When I do that, I get two copies of the Archicad model geometery. One model has all of the settings for the materials that were made. The imported model does not have any adjusted TM materials. I can delete the older model that is not linked but then I have to reset all of the material adjustments again. This has happened multiple times and I keep losing valuable time. Do you have a suggest? Thank you for your help.
