Favorite alternative to Preform for supports

Neat - can it create arched supports like I did here?

Edit: I gave it a quick test run - really not impressed with their onboarding process. The first thing it wants you to do is create an account, then it sits there for a while (phoning home?) before the software starts working. It feels way too cloud connected, and there’s advertising for the “Pro” version plastered all over. I wouldn’t mind paying, but the taste the test drive left in my mouth doesn’t feel good. Shame is it might be great software but some unprofessional choices by their product manager turned me right off. Feel free to comment on any of this and convince me otherwise :-).
