Is it possible that I can subdivide a shape in blender to add new faces, and keep its shape. More specifically it's a rectangle and when I subdivide it the shape changes.

This is before the subdivision:

This is after:

  • $\begingroup$ How did you subdivide it? Did you do this in Edit mode, with a modifier or by another mean? $\endgroup$ Commented Feb 22, 2022 at 13:53
  • $\begingroup$ How did you subdivide it? If you select All in Edit mode then right-click and choose 'Subdivide' there's no way the overall shape of a cube should change. $\endgroup$

  • $\begingroup$ if you've right clicked > Subdivide, look into the Operator box (panel on the bottom left), make sure that the Smoothness value is at 0 $\endgroup$

There are two options:

1. Instead of the default "Catmull-Clark", using the "Simple" mode of the Subdivision Surface modifier will retain the shape of your mesh. Since this is a modifier, you can change the parameters later down the line:

2. You can enter into Edit Mode, select the geometry you wish to subdivide, right click and select "Subdivide". You can change the parameters in the "Adjust Last Operation" menu in the bottom-left corner (shortcut: F9), but since this is an Edit Mode operation, the changes are permanent once you take another action.
