Green Toaster's Car Sketches

Thanks for the suggestion - I tried it but it's substantially different from the original wireframe model and the model I did using another program which has a flat surface on top with variable radius tangent arcs or conics bordering a perimeter of different sized ellipses.

I can keep working with it - I'm not used to modeling this way - with these tools. This is not a complaint, but just an observation that it looks like I'm going to have to (1) learn what SU can do, then (2) model what I want rather than modeling with a limited understanding of how to get the job done.

A quick tip GT, that you probably already know... but when you select the Circle tool, you can type in the VCB (Value Control Box) and hit Enter, to add a higher number of edges that make up the circumference of the circle. This will give you a smoother curve to work with in your geometry.

Cheers,

Thanks Craig - when I begin some serious modeling I'll work with changing that value. I've tried it before and it works great - like when I intersected two stretched spheres and removed material - higher number = smoother edges at trim line = higher regeneration time.

BTW - I used to ride SV-650, CBR900RR, GSF-400, Ducati 900SS, plus 38 others. After my last two crashes I gave it up completely. I'll always want another bike. (snif)

depending how much wire u want to use u can make different qualityes, here a use medium quality
So, did you use the Sandbox --> From Contours tool, or what? I don't remember seeing a means of adjusting the quality - is this done before the surface is created - when the arcs were created?

Sorry to be so clueless - thanks for the help.

ely862me · 24 Jan 2008, 21:39

i didn t use the sandbox i use the hand
i alway do this i fit them with hand the sanbox isn t precise
i said medium quality because i wasn t use too many lines how do u expect to sandbox made a nice hood i use sandbox only for two lines two arches or something like that(i was using sandbox for the windows of my concept cars)

GreenToaster · 25 Jan 2008, 00:56

Sorry, but I still don't understand how you get your surfaces in there and they render so smooth - looks like you converted the one I started with - I feel like I'm the dragon inside the shell - almost strong enough to break out of the egg and fly.

ely862me · 25 Jan 2008, 02:33

i didn t coverted i make it again,for makeing a desired surface u must have enough wire to fill exactly that form what u wish to do so u make a bigger arch on the bottom then one smaller then another smaller then another smaller when u gonna fit the wires is gonna be a nice rounded form smoth it and is gonna be exactly how u want to be

GreenToaster · 25 Jan 2008, 02:51

Okay - thank you, I'll try it - I think I (finally) understand how you did it.

I'll post my experiment on Friday.

Thanks again,

Brad

here is a little part from my new concept car, as i was talking u must make the wires after that fit them of cource u must have in mind the desifn of the car else u can t do a car, right? the position of the weels is taken from another concept of mine and i modified a litlle the lenght

boofredlay · 25 Jan 2008, 22:46

Using Bruce's method (a bit higher poly) and playing with This Script I generated these.

GreenToaster · 25 Jan 2008, 23:19

%(#000080)[Thanks all! I was able to figure out what I call "bubble shaping" where the sphere is squished, cut, & so forth (see my "bubble" car on or near the first page of this thread) but thanks very much modelhead for sharing that with everyone - a great techinque.

ely862me, that's really nice you posted those images and included some explanation. I've never modeled anything before using that technique although today I tried without much success.

@unknownuser said:

There is no doubt that stiching a model together is most accurate but not many of us have that kind of time luxury.
Yes, this looks like a time consuming approach - I'm used to other tools, but I'm not an expert with the cool looking stuff: surfaces! I've been using Pro/E for years and my surfacing capabilities aren't well developed. I'm looking forward to getting this technique down.

I'm not very confident I can figure out how to "see" the model first - your words are very true and I believe some people have a natural ability to do this sort of thing where some do not. I clearly am in the latter category. I can "chop & chisel" flat surfaces all day - easy - but creating those beautiful smooth amorphic surfaces - wow, very impressive. Your images and words are very helpful & encouraging. I'm going to try again with something simple later tonight.

Boofredlay, that's a very nice script but I'm not sure how I could use it yet - thanks for posting it and showing the very nice examples.

Happy Sketching,

Brad]

boofredlay · 25 Jan 2008, 23:33

Brad, the script is excellent for creating a thickness of an odd shape. Look at the solid one of the two shapes. This could prove very useful in making many car components FWIW.
Cheers.

GreenToaster · 26 Jan 2008, 00:06

Boofredlay, thanks, I'll play with it.

Here is my first "real" attempt at stitching (is that what I'm doing?).

I can see how this is going to be lots of fun - a few questions:

[1] --> Does it look like I may be on the right track?

[2, 3, & 4] --> I have SketchUp Pro - doesn't it have high quality rendering built in? How do I take my very rough hood and make it "nice" and smooth? Do I just add more triangles?

Thanks,

Brad

. . . 2nd attempt . . . just playin' around, nothing serious - this has some interesting possibilities for sure.

I wanted to take a circular surface and blend it quickly into two conics . . . I have lots to learn . . . but it's fun.

ely862me · 26 Jan 2008, 01:58

i know and i agree that my tehnique takes time but look what i can do with it,sincerly i can t imagine to make cars helped by spheres or else of cource if u play a lot with it u can do nice things
u ll see soon this car in warehouse i must finish the interior,front and rear lights and some little things

ely862me · 26 Jan 2008, 08:42

this is not finished but i couldn rezist to not take a picture

I think your work is outstanding.
I agree 100% - very inspirational, artistic, and very cool!!!

I'd be very happy to be at your level of modeling & creativity - so, I'm going to press on and learn how.

Thanks ely862me!!!

GreenToaster · 26 Jan 2008, 14:07

Here's a quick attempt at this technique - there is much to learn, like what is smoothing - when should it be used - why can't I see my surface edges anymore?

AND - I just discovered arcs are dimension driven so it's easy to change them quickly!!! Wow, that's a nice feature.

Thanks

Gaieus · 26 Jan 2008, 14:18

Brad,

Until you start "handstitching" an arc (and thus ruining its curve entity), you can always hover over its middle endpoitn and modify its bulge. So just quickly draw the arc in the direction you desire and you can play with its bulging later (often you cannot pull it up enough because of some disturbing inferencing).
