I recently saw a video on YouTube.
The YouTuber in the video created a closed curve with 4 lines and a closed extrusion with the curve.
Then, without any command, the surface of the closed extrusion was selected and offset.
So I tried to imitate this scene, but it didn’t work out.
I would appreciate it if you could explain how the scene in this video goes.
From 1 minute 10 seconds to 1 minute 30 seconds of this video, the situation I was talking about comes out.
1 minute and 25 seconds to be exact.
