"short edges" in Blender?

Does Blender have a “short edges” issue like that in Wngs3D?

In Wings, it is impossible to connect vertices that are extrmely close to each other, or to cut edges that are extremely short. So if you’re modeling something with small details, you have to make sure your model is large enough to make sure that you don’t end up with these “short edges”.

Does this ever hapen in Blender?


you can remove vertices that are exactly in the same place by selecting the vertices and pressind ‘W’ and chosing ‘Remove doubles’, or you can select two vertices and press Alt + m and you’ll get a menu from which you can chose how to merge the vertices
