If you do not have access to CINEMA 4D software, your only option would be to use some of the 3rd party conversion utilities, such as PolyTrans|CAD+DCC to convert your 3ds Max graphics to C4D format. Both of these formats are proprietary, so your options in this case for 3ds to c4d conversion are somewhat limited.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned 3ds to c4d. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
