Civil engineers can earn dollars in international and foreign projects if they have the necessary expertise and skills. In this case, the civil engineer can work as a technical consultant, project manager, design engineer, technical supervisor, etc. in construction projects abroad. But if you plan to earn dollars as a freelancer, you should pay attention to an important point. Considering that the design in the field of civil engineering using specialized civil engineering software must be done according to the regulations of different countries, it is a little difficult to earn dollars as a freelancer in this field with different software because each country has its own regulations. Therefore, in order to earn dollars as a freelancer in the field of civil design, you must be familiar with the relevant regulations, which may not be possible for many people. But to earn dollars, you can do shop drawing work using Tekla Structureser software and earn dollars because doing this is less dependent on regulations, so you can earn dollars through this software in Iran. Cryptocurrency is much more than a financial innovation.
