Hello Bea, Greetings!

It’s totally fine if you’re bad at drawing . Architecture just needs a medium to express it.

Whether it is drawing or software, all you need to know is that you can express your thoughts through a medium. Once you can communicate your thoughts to a physical form you’re good to go.

So your priority should be to practice drawing to an extent that your educational career completes. Other than that you can totally shift to software in terms of working and all.

Thank you, hope this helps.
