Yes, Tekla is a BIM software. BIM stands for Building Information Modeling, and it is a process that uses 3D models to create, manage, and share information about a building project. Tekla Structures is a software program that allows users to create 3D models of buildings, bridges, and other structures. It can also be used to generate detailed fabrication and erection drawings, as well as reports and data sheets.

Tekla Structures is a powerful software program that can be used to detail a wide variety of structures. Here are some of the different types of detailing that can be done in Tekla:

• Steel detailing.
• Concrete detailing.
• Precast detailing.
• Miscellaneous detailing: Tekla can also be used to detail a variety of other structures, such as timber structures, masonry structures, and hybrid structures

Tekla software can be used for a wide range of applications in the construction industry. Some of the most common uses of Tekla software include:

• Building design: Tekla software can be used to design all types of buildings, from small residential homes to large skyscrapers.
• Bridge design: Tekla software can be used to design bridges of all types, including suspension bridges, cable-stayed bridges, and truss bridges.
• Offshore structures: Tekla software can be used to design offshore structures, such as oil platforms, wind turbines, and floating LNG terminals.
• Industrial structures: Tekla software can be used to design industrial structures, such as factories, power plants, and warehouses.
• Heavy civil structures: Tekla software can be used to design heavy civil structures, such as bridges, tunnels, and dams.

A steel detailer should capable to read contract drawings properly, then only they can do work perfectly with the help of Tekla. So both technical and software knowledge need to enter steel detailing industry.
