change sketch proportions

[vinci16]

Hello everyone,
I would need to change the proportions of a sketch created following an image to be recalculated.
now the problem is that you have changed the proportions of the sketch and the file has been saved.
I insert photos to make understand the problem, the blue sketch is what was modified by mistake while the image below is the correct size in which it was created.
Thank you all for your help.

inside the sketch, all selections, sketch tools>scala

Thanks, I had found the scale function but I didn't realize that I had to first extrude to be able to use it.

 

[MassiVonWeizen]

really exists the scale function within the sketch. and I even wrote it Sketch tools > scale

 

[vinci16]

Yes, I used it in already extruded sketch.
Thank you.

only to punctuate; One thing is to say that the sketch scale tool you used it after extruding the sketch (at that point you could use the scale function to work directly on the body) and another is to say that in order to run the sketch scale tool you must first extrude it.
the second is a wrong statement

simply the program didn't allow me to use the 'scalator' function (including 'sweet' and therefore not usable) both in the modification of the sketch and after finishing the sketch but without having extruded it.

very strange because before writing it I checked it
