Title: How to extrude all edges 1cm from center point?
Tags: modeling
Question: How can you extrude all these edges 1 cm away from the center point, thus creating a rectangle 1 cm larger in all directions?
Blend file here also, the desired edges are already selected:

Here is the accepted answer: With the loop selected, press AltS to scale it
along the normals.
Press S again to activate Even Thickness, so you define the actual width of the border instead of the corner edges' length.
Enter -.01 to get a border of 1cm width.
The edges don't provide normals to scale along, so the adjacent faces' normals are used, which are pointing inwards. This is why you have to enter a negative distance.
Comment for this answer: I tried that now, but i believe it scaled the edges .01 (1 percent) bigger. It didn't move each individual edge 1cm further from the inner edges.
Comment for this answer: did u apply scale before atl+s
Comment for this answer: Yes, the scale and rotation was applied, i confirmed it also from the side panel where it says scale and so on.
Comment for this answer: Change the pivot from 3d cursor to individual origins
Comment for this answer: You're right. This method creates a diagonal edge with a distance of 1cm, when the Y-position is the same. You have to press S after Alt+S to enable the `Even Thickness` option. I will edit my answer accordingly.
Comment for this answer: With pivot at individual origins, it lifts the whole edge loop.
Comment for this answer: Yes! Even thickness did the trick, with 3D cursor being at the spot it's at. Thank you!
Comment for this answer: Just found out, if i extrude the edge, then cancel extrusion and do the same trick, the even thickness setting does not function anymore?
Comment for this answer: For the lack of a faster method, you can `Mesh > Transform > Push/Pull` the loop in both axis separately. This way you can still enter exact distances.
Comment for this answer: If i extrude the edges even a tiny bit forward on the y axle and then use Alt+S + S, it works flawlessly, then move the result back where i want it. I believe it needs the normal directions of the resultant faces from the extrusion for Even thickness to work, so the faces that are created with at least a bit of movement give that normal direction.
