How to join sketchup 3D model in

I added some 3DMAX from the Internet model, how can we use in sketchup? I can not find me in in the sketchup models under

sketch models and 3D are not the same as what you

to the documents into 3D MAX 3DS format and then import to sketchup, but seemingly can map to re-paste

in the 3D model will export to 3DS format and then import the sketchup on the line, but is said to run into problems, have the time or go on-line right under the draft model insurance more
