Hi, Since you are just starting out you should know that if you can’t find the answer on the wiki manual or by searching the forum and have to ask in a thread you should help yourself by posting as much information as possible, not give it out on a ‘need-to-know’ basis, because you’re not up to speed on what is needed yet.
Point: there’s no way without knowing what this object is anyone could use that tiny image to model anything. You obviously know, but to help you we need to know too. Picture references are useful when you have two or three views. Top and front views essential for this object at least.
Also, don’t be secretive about what the object is. Gas pump handle? Spaceship? I happen to know that this is part of the suspension for a high performance race car, but not everyone will. See what I mean?
Point: when you provide a link to a video tutorial you are essentially asking people to sit through a one or two hour video to help you with your project. Or be familiar with the video. You’ll find both kinds of people here, but to get the most help you should boil down your question so that someone on the boards does not have to spend a lot of time actually figuring out what you are trying to do. that way they can spend more time coming up with a solution, right?
Point: If you don’t use the right terms, people get confused. Subdivision sculpting doesn’t mean anything, so people could interpret it in a few different ways. Likewise with square control cage. Both of these terms could refer to somewhat advanced modeling practices, unnecessary for what you are trying to do…
