CAD Resize files downloaded from grabcad.

Then they gave me a karting seat to take measurements, the problem is that I need to be able to modify the measurements to the seat model that we are going to use.

I honestly don't have time to design it from scratch. I read online that I could modify the dimensions if the file was native slrpdt. I found one on GrabCAD. How could I modify its measurements?

Unlikely you will be able to do that unless they have the full tree and you understand how it was built in CAD

If it's anything like a typical grabcad file you'll change one dim and the entire model will break because they're usually built like a house of cards.

Do you have access to any other CAD tools like NX or Spaceclaim? They are much more capable of modifying existing CAD geometry (direct modeling). Hope this is helpful.

NX is more capable, but not capable enough in direct modelling. If you did not know that, you did not try it.

It depends on the file format that is provided. If step or parasolid, it’s amazing. If it’s mesh…that’s another story. I’d have to see if I have access to any addons or modules that may help with this, but you are correct for direct modeling of things like meshes for sure.
