How do I add a curve to a vertex to bend an edge / face Context: I'm extremely new to Blender (using Mac) and 3D modelling in general and I'm trying to add the final touches on my first model.
For my model, I am aiming to construct a 3D model of a box packaging for a product using the die cut I have received from the manufacturer. I intend to import my final model into Adobe Dimension so I can texturise it and add my mockup label.
I have managed to create my box ~90% with as accurate dimensions as I can. I have achieved this by starting out with a cube and extruded faces and adding edges. My issue lies in the remaining 10% whereby I need to add some curves to my model.
This is my model so far ~90%

What I need to adjust are the curves on the side and back to be similar to the die cut as illustrated below


Essentially, I need to adjust my faces/edges of my model to look something like this:


I come from a graphic design background and so am used to drawing objects and shapes using Pen tools and adding curves via handles. As such, I would greatly appreciate the a full walkthrough to the solution as if you were to explain it to a 5 year old :)
Thanks in advance!
Use a Bevel (Ctrl + B) on the edges you want to curve. Once you have beveled, select &quot;Custom Profile&quot; from the operator panel that appears, and you can define all aspects of the bevel, including custom curvature. In the example below, I deformed it heavily on purpose just to demonstrate. If you line up your object in front of a reference image, you can replicate the curve precisely.
