Reply To: I dont know why iam not able to make a proper face as shown in the video using the edges

Maybe give us some more information. Do you want to fill in the face or have you already filled it in on the picture and are wondering about the distortion?

The first thing I would always do with distortion is to set normals correctly. So you would have to recalculate the normals once with Alt+N But if you want to form a face with the marked edges on the picture, there will probably also be a distortion because the upper edge of the triangle is “too long”. I don’t know how to explain this, but try to create the face like this

This can lead to problems like this, especially on an uneven surface
