I am pretty new at all of this, so please help. I don't really know what I did, but when I want to print out my 2D project all openings (windows and doors) and elevetion lines are in red. This was not so before I did something.
Hi Berry, thank you so much for your reply...unfortunately it didn't solve my problem. As you can see, i did fix one doors partially. I tried to do what you recommended on the windows but it didn't happened anything. Any more suggestion?
