Tell your client to send you the FBX file (not the 3ds Max), then you can import it like this - Import FBX, but it is best to use Transmutr or Skimp instead, to make it lowpoly for SketchUp.
If you only have the 3ds Max file, then open it in 3ds Max and export it as an OBJ file, which is also good to turn into a lowpoly object with one of the previously recommended software.
Ok, I was just going to purchase it from here. Looks like it has an FBX file included? I just didn’t know if I needed a separate program to convert 3dsmax files. I don’t actually have a copy of 3dsmax (I am on a Mac but could probably get access to a PC).
