Depends on what you are modeling, only practice can improve you, not theory; post something you really are having difficult with, so someone can help you. Lastly, tris aren't evil, either :)
Thank you Super, you were right :) @perna , I wanted to ask you some Yes/No questions if you have the time to answer: 1-The first FFD box you called WIDE stretch, which doesn't really look like it does anything, you put there in order to adjust the width of the segment in order for it to later bend correctly into a…
@Wintersun Not quite sure what you mean but it looks like you want something like this: It functions the same as your normal grid. When you create primitives they will be aligned to that grid, you can snap to it etc. When your done with it you can reactivate the homegrid or just delete it.
You have to build the "heart" out of those extruded shapes, this mean that you first make them tracing the reference, then, with the edges you got, you make the rest of the mask. With your method you're pretending that the topology will follow another shape just because you made some cuts.
so I made a very rough boolean opeartion, after that I did manual cleanup for edge flow on open area for engine section just to give you an idea. There are number of approaches you can take though, You can try spline cage method for modelling this as one highpoly mesh, most commonly used for modelling cars. However I would…
