Hi Minh, Let me install the latest update, then I'll contact you again if the problem persists. I am a bit surprised that you didn't experience any problems with the Trace & Reference and the Object library. Regards,Rodrigo.

Hi Minh,I am sorry for the late reply.I have sent the samples to you via the file request form you sent me last time. I also sent my project because Archicad also freezes every time I try downloading/using an object. Please turn on the Trace & Refere...

Hi Minh,Thank you for your reply. I very much appreciate your help.I tried to work with Trace & Reference off—it seems to work much better; I don't understand the problem, as I have always worked using this tool. Regards,Rodrigo.

Hi Minh,I already sent it to you.Regards,Rodrigo.

It's ok, Minh. I wait for the message. Thank you,Rodrigo.
