Hello again!

here is my second project...

This is not the best of mine... I can see my mistakes in construction and planning. However, I tried to use all the tools you taught.

Here is my project: 

 

 

 

 

I am sharing the link of my work:

I am sharing the ss of my workplace. have a look at the tags I made 

 

 

There is one thing I want to ask. I can't hide lines. is there any way I can erase every line without selecting and hiding each line? 

I searched it on youtube and found out that I can edit in the styles tab... but once I turn off edge or profile, it turns on automatically whenever I click another scene and come back on that scene again.
