Repeat patterns

Hello, 

I heard the opinion that Corel Draw is not good for creating repeat pattern designs since 'the entire industry' use Adobe software and one can only work with the clients exchanging stuff made in Adobe. Is that true? I am a fashion designer, I have been using Corel Draw for over 10 years making random vectors, flats, putting together some art forms, but I want to start creating the repeats. Unfortunately, everyone saying that I shouldn't be doing it using Corel Draw... I like Corel Draw, I invested time and money to learn how to use it and to use it legally. I know that there are some special, additional options to make repeat patterns in Adobe... Can you share your experience of making repeat patterns in Corel? I know that in Adobe you work on layers.. Is it wise to try to make it on Corel Draw or should I just learn how to do it in Adobe software? Honest question. Greetings, A.
