Hi, great to see this new tut, I'm getting my hand on it right now.
Maybe it would be a good idea to have one subforum and a thread for each tutorial so that people could ask questions on that specific tutorial or see if it has already been answered. People could also upload there their finished render and compare to each other. Just an idea. Anyways, I'll be posting some doubts or things that are not clear here.

Ok, first question...
In step1, after InterpCrv when doing the sweep2. My mesh seems different than urs, more dense. Why is that? Not a big problem, but maybe settings here are different than urs
p.s: you could tell people the lenght of ur background image.
-
there, I knew there was something wrong... After that, i make the ellipse, try to project but it to the surfaces, but it misses it... I know I could extrude and then duplicate the intersection edge, but it's a bit too early to be having this differences right?
Anyways, I'll do that because I can't continue if I don't...
-
New question.
Still in Part1, 2nd page, 2nd picture.
When u offset the curve, do you use a specific value? I had to use the Through point thing and now I have to split the curve. I don't know if this is what u did and forgot to explain or it's just me doing something wrong (i did move the circle 2mm inwards)
-
When scaling the ellipses after arraying 24 times, is there a way to make this even? I mean, u made 5 rows with approximately proportional distances. What if we want to be precise, can we do it?
I'm like a beta tester of ur tutorial =)
-
Well, dunno where I scrwed up because I could join the object for filleting... Had to go to properties and increase the absolute tolerance to to join them. Anyways, here is by the end of step1, i think it's looking good.
-
In beggining of step2 ur first circle is not 6.5mm radius i think, it looks a lot smaller than that... Here's what I have.
Also, what's first radius for the first circle on the second part of step2? Did u use the circle of step1? Not sure whis one is it there since you offset it aftewards.
I'm out for today, will finish this thing tomorrow if I have time. I hope you don't take all these questions the wrong way, I'm just trying to help making some things more clear.

Ok, first let me tell you that your feedback is much appreciated and obviously needed, as I really need to fix this tutorial. It is pretty good, but in the end I didn't really write a good tutorial. So, I'm fixing it now.
And thanks for corrections, it would be a pain in the ass for me to go through the tutorial myself again and search for errors ;) so, you're more than helpful.
First, for the little 6.5mm radius, you are right, it is completely wrong, it should be 2mm [FIXED]
Second, the circle in the second part of step2 is the same curve as the one we used for inner surface of shell, and that circle is again offset inwards by 2mm.
As for scaling the ellipses to be the same aspect ratio, you could use two same reference points. When scaling you need to set first reference point, and then the second. If you use the same two reference points for all 5 sets of 24 ellipses then you will get them all scaled down with same factor. Of course, the origin point also must be the same.
For offseting the curve, in step2, it is done for our shell. As I said the shell will be 2mm thick. After you offset it, you should Turn on the control points, and move the end point to Quad Point on the circle. You don't have to do this, but this way you won't get messy.
- And I see you offset the curve that is 120mm in length. I said it could be done that way, but I made another curve, using the same method as making the first one. (but maybe it was me who messed things up in the tut. I will go through it later today and fix other stupid things. Maybe even rewrite it)
p.s.
the length of reference image is 190mm
sorry

Hey, I didn't go to sleep yet. It's 10 am, I wanted to see one episode of prison break and I couldn't leave it so I finished the whole season, lol
I'll check what you wrote on my model later, I kinda need to go to bed now!
About rewriting, I think there's no need to it, I think it's very good. Anyways, I'll continue making the tutorial and telling you the things I find that need to be corrected.
Oh, and yes, I can imagine that going all over again must be a real pain in the ass, so don't worry, if I cannot help you writing tutorials because I'm not very good, I'll help you correcting them because as I'm not good I'll get stuck =)
I'll try to look into it tonight!
Great to have a new subforum
Cya!

I'm doing step 4 of the tutorial, so far there have been no problems. Oh well, just one. I was too lazy to make the inner shell of the handle so I couldn't do the blendSrf thing, I'll figure a way of closing this without making it =)
Anyways, back to what I wanted to tell you. I think that when u match the curve edges to preserve tangency there's a better way for doing it, letting you have more control too.
When I want to make a curve tangent to another curve, what i do is display the control points of the 1st curve, and I draw a line from the end point, position the mouse on the nearest point, hit the tab key and go to the other side so i get a line tangent to the curve. After that to make the second curve, I position the first point of the new curve in the end point of the other, and the second one in the line tangent to the curve. The third point and so on will be where u want the curve, and the last 2 points should be aligned to to keep tangency when you mirror.
I know this is a curve and a line, so just placing the 2nd point of the curve in the direction of the line is enough. I just don't like to let rhino do these things for me, I don't trust much in the app, lol. That's the reason I don't like fillets too, i prefer to make te shape already rounded from the beggining. It's more work I know, but I feel more comfortable this way.
I don't know if I'll be able to finish the tutorial tonight, it's been a really long day, I'll try though

See, I told you, I just tryied is ur way and the tip has a curvature problem. Anyways, you will trim this part later, so it's not a big deal
-
"Next, make an ellipse. First end of axis is at 77m, and second at 22mm. (select Diameter from command options selection). And then make another ellipse, again use Diameter, and set 4×14mm. Position both centres of these two ellipses in the same point."
There is no way that second ellipse is 4x14. I tryied 48 and it's about what you have in your image, don't really know the real number
-
Well, there is absolutely no way of trimming / spliting there 2 surfaces. They are not exactly the same as yours and it won't be a big deal cause I will change them a bit and I guess it's solved. But what if you don't want to change those surfaces? Why does it say they don't intesect the second time I try to trim if they did the first time? How to solve this? (general question)

yes, it is 48mm, I guess my 8 key didn't work when I was typing. I must say I wrote this tutorial in the middle of night as I didn't want to postpone my duties to this site any more, so I was really tired :D

pls send just these two surfaces with their curves so I can look into it. This smaller ellipse looks a bit strange from this image...

The tutorial was really good, loved it! =) Thanks a lot!
Here are some render, I need to work a little bit on the materials and the noise, but will do that later. I didn't find any more mistakes, although for a beginner it may be tough to follow at the end. But, they should make ur other tuts first...
Thanks!

yeah, I'll use your renders for index page... You are really getting somewhere with it. I personally don't have much time to start experimenting with rendering.
-
Sure, that will be great =)
I'll try to make those renders better and I'll upload them.
Oh, another thing, the other time I tryied to upload something in the gallery but it didn't work. I also tryied to create a gallery and upload there, and didn't work either. Maybe you should check it out.
Another thing, great news for me. I went yesterday to a job interview and they'll hire me for a month on trial to see if we can work together. I think I never told u, I'm studying Industrial Design, that's why I was learning Rhino. They told me they expect a good level for the program so I guess this weekend I'll finish the other tuts =) and if I have some time I'll try making something myself.
I'll post the new renders later, thanks!

well, here are the two finished renders, I know there are some things i should take care of, but I want to move on.

Oh, sorry for delay, Congrats on the job interview, and seeing your results here I'm sure they will hire you permanently. I just hope that won't take most of your free time :D it would get quiet here without you ;)
