My idea is to Modeling on sketchup and then exporting to Cinema4d to UVMaping the model,
Is it possible to do?
Sorry for my english 
Hello. I believe it is possible to import your file into Cinema4D, especially considering that it supports SKP files. Have a look at this.
Formats Supported by Cinema 4D
How can I use a .skp file?
I Generally export from sketchup a .fbx file and then I open it in Cinema4d.
The Cinema 4D R17 release has a built in SKP import option. A Google search brought up this this video tutorial which explains the whole process.
Oh thank you, so what of those two is the better way?
Using a .fbx file or a .skp file to working into cinema 4d?
