5 minutes for the reserve all command sounds quite extreme.
As a first step save out a pln from the project and share it again. This will help to clear out the reservation table. If the error remains after this I recommend to get in touch with our local support team for further investigation.
Hi sorry for the delay but I try to follow your suggestions and stil the same story evenI contact graphisoft in USA and they still not give me an answer.
In addition of that in 3D view I have the following window, and I run Teamwork Archicad with the most released patch # 5021
Thanks
