Extrusion at perfect angle problem

Hi Guys!.

I really don't know how to extrude it in such a way that it's equal at every angle since it's not exactly at the Y or X axis. I tried many transform orientation. Nothing works. I'm stuck. I try to do the same as the teacher. He extrude, then he does ALT S. I can't do the same even though I type the same commands. Look at Modeling the Hands II at 38:49. Here is my file. It's the selected vertices. My file 

Thx cause I lost so much time in it and I need to go to work. I feel that I'm not productive and I must admit that I cursed a lot by yelling in my appartement lol.

    I see what you mean. When I open your file and try to scale along the normals (ALT+S), if I go too far the thing begins to get all wonky. But when I see in the video, JL doesn't go that far in, if you notice he only ALT+S very little, he mostly does a regular scaling operation, probably because he too can't go far either. In your file, if you hit Shift + 3 in the numpad, you'll go into the local angle view and you can hand place your loop from there. All in all, it's not a full ALT + S that you should be doing, you can get your results with normal scale as JL does.

    thx!

    So as I can understand, he extrude, cancel it and do a slight ALT S and he kinda reajust the direction of the vertices. So I did try to understand something that I could not do and impossible to do. I misundertood the teacher's operation there.

    But I still have a question. Is it possible, in my file I shared, to extrude in a single straight direction?Cause I can't and by hand, you extrude in all direction.... I do it all the time, so why it doesnt work there???

    You can see that I did some perfect extrusion in my model. So I am mixed up.

    I was frustrated cause when I feel I don't progress and I need to go to work, I just wanna finish what I started and I don't feel like going to work. lol I like when I feel I progressed. I am very happy that Cgcookie has a nice staff that answer your questions so fast.

    Thanks Max. For that extrusion part or the scaling along the normals, Blender a lot of times acts wonky when you try to do an operation like extruding or scaling and it all has to do with the direction the normals are pointing. There's no easy way to control that, other than being mindful of your local orientations and such. It feels easy when your axis are aligned with the world, but when we start introducing rotations, moving vertices around, subdiving, etc, transforms operations go all over the place. So from time to time we have to manually readjust things, it's no big deal really. 

    One tactic JL does all the time is aligning the transforms local axis to the object. It's a way of getting so decent alignment when you have lost them. You can see it here, around 17:50

    Also you can watch quick refreshers on transforms orientations here:

    And a refresher of Normals here:

    And orientations and pivots refresher:

    All those stuff go hand in hand with the problems you are experiencing. Blender and 3D in general is a big beast to slain, it doesn't go down easy. But if you keep at it, you'll see how you can control the beast and make it your friend. Like the lady in Game of Thrones and had Dragons as pets. That can be you if you master this, so keep at it, it'll get easier and easier

    I watched all of your videos. The first one, I even have a script to make it short in one operation. The other videos are a quick reminder and the way he explain it is so good. It's not easy to explain and he does it very well. I thought of something. You can creat a ''Placebo'' plane object from a cursor that has been placed in Face orientation. Then you can take a side of the plane as a face orientation. From there you can extrude the vertices from my Blender file in relation with that face orientation. So the extrusion would be in a straight line. 


    Just a thought. I don't know if it makes sense... Maybe not. But we have to guess and try to find different solutions.

    Thank you very much for your help.

    Dude that's a great idea and solution. I had never thought of that and I see how it can totally work. Take a proxy object, align orientations to the desired goal and create a custom transform from that. Brilliant. Sounds like you just leveled up big time Max, you went through a boss battle and got tons of XP.

    I don't know if it makes sense... I will try it. it' just a thought.

    I just created a video of my ultimate solution on another post. Watch the video and the file, and tell me what you think.
