How do I modify a design?

I am new to the community, and have found many amazing creations. I would like to modify some trophy designs to create trophies for my kids at school. Is there a way to change text on a design that I download?

You Need basically 2 things:
1. Desired 3D model
2. A CAD software that can handle the 3D model Format.

If it is a STL Format, you will Need another step in between the two mentioned above.
A Software calldef meshlab (or similar other Software) to convert it into editable Format, that most of the 3D CAD software can handle.
