I'm fairly calm, and also not a dude.
Here's another spooky story for you: I've been drawing all my life, and have, though hard work, acquired artistic skills that I am quite proud of. I've faced my artistic limitations, and I have worked hard to overcome them - with pencil, paper and real life skills. It used to be I couldn't draw people in profile, and avoided drawing houses like the plague - but now I don't, because I've worked hard to learn. 99% of my comic is drawn without tool-assisted perspective, because most of the time, I don't need it.
And I still think perspective-tools are a useful thing to have. Did you know, using perspective-tools can be a nice first step to help people wrap their heads around the rules of perspective, which can be hard for newbies to learn and understand? Did you know, it's perfectly possible to start out using perspective tools, and through doing so, begin to learn how to do it freehand?
It is perfectly possible to make comics in SAI. And it is perfectly possible to draw amazing things in SAI. I'm not denying this. All I'm saying is that Manga Studio, as a software, has certain advantages that SAI doesn't. That's my entire point.
@epiale In that case, you're working with a more up-to-date version of SAI than I am. If the newer versions have line-tools, that's great!
I'm now going to stop posting in this thread, because we're clearly not going to agree on anything.
