There are lot of .stl files is there, for clear view of each component, it should be colored different. It helps a lot to viewer. It is difficult to color each object manually. Is there any auto color all the components.

If I understand correctly, you are loading many .stl files, each with a different name, and showing them together. And you want them to have different colors.
The easiest way to do this is to select all of them in the `Pipeline Browser` and add the `Group Datasets`  filter. ParaView will apply a color map to the blocks.

I had the same issue. I followed your suggestion. However, the exported file is two separate files.
Is there a way to export a single STL file (a combination of multiple ones) with different colors?
Thank you in advance!
