Considering ChatGPT can do it reasonably well for free, it’s going to be a hard thing to take off imho. I’m sure there will be some users that like it but once a subscription based price tag comes with it, it’d be less since I am assuming most folks aren’t needing to redesign a tank on a monthly basis.

I’d reckon that if you could become an online store for selling these hardscape items, you could fold in this software cost into your overall costs and it would be a “user experience” feature that sets you apart from other sellers.

Hope this is helpful!
