Warning: No faces filled

No faces filled	No faces filled	无已填充面

Cause: You have selected an edge for which it is difficult to generate a surface.

If you select an edge for which it is difficult to generate a surface, “No faces filled” will be displayed.
Filling becomes difficult if the edge selection is complex.

Error occurrence procedure A:
1. [Edit mode] [Select edges] Select two edges.
2. [Edit mode] Right-click [Edge context menu] → [Fill] to display it.

Error occurrence procedure B:
1. [Edit mode] [Select edges] Select two edges.
2. [Edit mode] Click the header menu [Area] → [Fill] to display it.

Case 1: Edges are not connected

You can see it by enlarging it.

Case 2: side not closed

Edges are not selected to enclose the face and cannot be filled.

Case 3: Sides overlap

This is the side where the stripes (black and white dotted lines) overlap.

How to fill a face

1. [Object mode] [Edge selection] Select edges surrounding the face.
2. [Edge context menu] → [Fill].

3. The surface has been filled.

The previous solution may be helpful

Last time I wrote an article called How to fix when an object’s surface is displayed incorrectly [What is the strange shadow?], but I think you can also use the solution in that case.
