I was so happy to use the Tekla software in my study life. The software was so user friendly for various structures to build.My structure is about a Business Center where it has good parking area,from there people will come by walk to the building,where they can enter to ground floor from there by steps they can go to top floors and on the top floor it is constructed indifferent way which is one of new type of construct.The chairs are also placed where every one can use.So it one of new structure.I also have a great experience in using the software.Thanking you for giving this opportunity.
