For animation and rendering you can also use modo 601 or keyshot3.0. You can easily work with the files which have created in SolidWorks.
Thank you very much Arvind for your answer. So when I import a Solidworks model in these software (modo 601 or keyshot3.0) I will still have the original colours and materials of my design? And also can these softwares do what I want to achieve like laser beams moving within the system, apply cameras to follow the light path within the model (optical system) going through lenses, hiting mirrors and reflecting through cameras etc.
Thanks for your help
