Thanks @storyoferne for your warm welcome and I am always here with you all.
the current covib19 outbreak is really torturous and hopefully this month the people's economy will slowly grow back,
This project is quite complicated and in the next episode I will try to discuss how to make a simple frame in detail, so that architecture lovers can learn it easily.
Warm greetings to you and your family and friends, I hope you are always healthy there ;)
