How does the Transparency option in the Envelope Options menu work?

Question

Adobe Illustrator

I can't see what the Transparency option does , nor what the Clipping Mask option does . There are no changes to the layers. How can you see it?

Answer 1

I am not the biggest expert in Illustrator, and the topic is certainly covered many times in the available online tutorials. I don't think it's a long search. For example, something like compress.ru/article.aspx?id=12685 or another lesson specifically on the topic of "transparency".
