Hi,
There should be Upcomming improved Lasso tool in Krita's next versions.I was just thinking Krita would be then so perfect for designing cars with all profiles on one canvas or for even concept product designing.So why not make a dedicated tutorial or guide to Car designing or Product designing.
We have tutorials for Comics and Artwork with Krita,why not a single dedicated tutorial for product designers or car designers.
This software would be superior than Sketchbook pro or Corel Painter,which product or car designers normally use.

I just saw this:

Interesting!

Opps!
Looks like forum members are surprised that Krita can be used by a young car designer like me!
I was expecting atleast one response by now!Aready 23 views as of now!
As of now I don't have any screen shooting software,but I would really like to help creating a car design Tutorial for Krita.
I am still a student of Science and car designing,so am not perfect in this!

Here are some pics of car designing,so Krita developers will get some more idea,what Car designers want!These are not my sketches.My sketches are not yet revealed because I as of now dream to take it to production,better kept secret.

In few pics,you would notice many different profile views of car designs on one single canvas.

Here are three most interesting pics in the Same Flickr set:

Hi everyone,
A Demo video is more sufficient than words.
I request every Krita developer or every car designer to have a look at this video:

http://www.youtube.com/watch?v=7w3e-yI8qh0

This will explain the importance of a good Lasso tool in car designing.
Not only this,this is a must for any aspiring car designer.

Please refrain from crossposting the same post on several topics, this is unnecessary bumping and doesn't add any value.

Sorry for that.
That was because similar discussion was being continuing on different threads.Everything came to focus at similar points.Everything is interrelated and when we need same material at few places,we have to use the same content at some places in a limited amount.

In my future update on car designing,you will see some step by step instructions on Car designing,which is not discussed on other threads.

To make a tutorial on something, it is necessary to know how to draw that something in the first place. :P For example, I have No idea how to design cars, nor the techniques involved, so it would be absolutely impossible for me to make a car designing tutorial. In the same way, I don't get the impression that any of the other artists posting here (Deevad, Animtim, Kargall etc.) are specialized in designing cars. I don't even remember seeing cars in the art gallery here.

It seems the only one who knows anything about designing cars here is you, so if you want a car designing tutorial, I'm pretty sure you're the best person to make it. :) Such a tutorial would, of course, be very welcome.

Thanks a lot,
I am a newbie in car designing but am very passonate about it.Let my new tablet be delivered,then definately I am planning to do Video tutorials.

Any idea how can I record a live sketching demo?

By this time,I should have started doing different car designs or Product designs on Krita.But this hell Fujitsu Dealer is giving us excuses that the tablet will arrive this month.....,delay due to chrsitmas holidays....,within next week,etc.I was promised that the tablet would be delivered within 15 days of placing order.But unfortinutely,Fujitsu Couldn't kept the promise.Fujitsu India imports products from Germany and are made to order only.

I think that the car designing community is very silent in doing video tutorials and is not much introduced to Krita.I am trying to spread the word in the community to use Krita.

:) Ok by now you might have seen some video,pics etc regarding car designing.
Let us jump start some more detailed basic tutorial on Car designing

Let us start with "What do you need in car designing and what are few basic things you should keep in mind while designing cars?"

1) you need a big canvas of 28000 * 16000 for designing sedans and 24000 * 17000 with all profiles (side/back/front,isometric)on a single canvas,along with detail Taillamp or side indicator details there and there itself.
Designing these accessories seperately is not suggested by me since there's no proper synchronisation in the designing process.
Neither using different profiles on different profiles is recomended,because you then do not have proper synergy between different designs.
For example if you make a slight curvy change in design on one profile,you need same to be reflected in other profile,in different way in a synergy.
For this big size ,you can't use Sketchbook Pro or Corel Painter,etc.
Softwares like TV paint Animation,Krita Desktop,GIMP,NeoPaint (,and may be PD Howler Artist/Animation) support this big size.

2) Serif PhotoPlus,Photoshop and Corel Photopaint although support this much big size,but there's a problem with Image Display Quality of the file on these softwares especially on a display of 13.3 inch screen.The lines appear as rough and not please to the eyes when using these two softwares.
I wish that the display quality of these softwares is improved then it will be suitable for car designing.

3) Ideas and Interiors:

Please see maximum no. of videos,maximum car designs,maximum sketching images,etc. to get an idea.Still Imagination capability is most important.No one can teach much in that.

When interiors are considered,more info can be added here by me or someone.You may need Vector editing softwares like adobe Illustrator or Corel Draw for interiors for giving wood Finish,Sliver finish,etc.

Please see:
1) http://flic.kr/p/dCzJai
2) http://flic.kr/p/dCzJ86

4)Representation:

Well,this is very important aspect of car designing.
I did adviced you all to design all profiles on one single canvas.
But it may not work out very well for detailed representation of your design.

so just make duplicate electronic copies of your designs and trim off other profiles keeping one profiles each for every duplicate file.
So that you can print larger image on paper for detailed views.

5) Real life Shading effects with Airbrushing and a Good Precise Lasso tool.

You might wonder why lasso tool is necessary in painting and sketching as krita is made for sketching and painting and not for Photoediting ,but in reality,for product designers,it is one of the most important feature,without which its not possible to give proper shading to side view profiles of car designs.The technique used by car designers to give light effects or shading to side profile is to use lasso tool and apply light airbrush with little transparency,over it.That is why,Lasso tool is important for doing special real life effects.So having good lasso tool is equally important in Krita,which should be allmost exactly similar to what available in Adobe Photoshop or Sketchbook Pro.

:z Remember that using shading effects with lasso tool is recomended on a new Layer,not the same layer.If you use the same layer,you cannot easily edit your designs. :z

Now this is well illustrated in this video (Very very very Important to see) :)
(http://www.youtube.com/watch?v=7w3e-yI8qh0)

Unfortunately Krita 2.5.9 and GIMP 2.8.2 both lack a good Lasso tool(A good lasso tool is expected in new versions of both the softwares.).
Sometimes,Car designers do a really complicated selection in car designing or product designing and you do need a good selection tool.The small squares which appear along the path of selection do not work out for precision.The selection should appear as moving discontinuous and thin line curves with small spacing.

@Neverindingo,
Now you can see that everything is interrelated,Lasso tool,Airbrushing,Tutorial.


Proper Airbrushing Techniques in Krita for Special Shading Effects:

Firstly,Make a new Layer

A)
Well in some cases,Feathering technique can be applied:

1. Make a selection
2. Top menu: Select -> Feather Selection. Don't be afraid to choose a huge value, like 20 or the likes.
3. Take one huge brush, preferably one that can cover the entire selection, and click over the selection just once. If you paint more over it, the less transparent areas will start to get painted over more.

You get something like this:

Special Thanks to Valerievk for her immense Contribution in this Information.

B)
If you want to Airbrush in such a way that fading is only on one side upwards and not on other side downwards due to possible light effects or shading Configuration,then in this case,Feathering Technique is not applicable.
Then you need to follow the following steps:

1)Select the first brush option in pixel brush in brush editor.Its image is displayed in the brush options menu.The first brush option is vissible as tight airbrush.
2)When you generally select pixel brush in brush editor,Airbrush mode is setup as default.You have to Unclick "Airbrush".

3)In the Brush Dialog,select Brush Tip and adjust spacing.The concept of spacing in Krita is slightly different than that in Photoshop or ArtRage.If you are regular Artrage or PS user,you will come to know what I mean by adjusting this in krita,since the adjusted brush is displayed in the dialog box.

4)Start using airbrush.

If airbrush mode is not unclicked,you will continue to get problem of intermediate high intensity as points on stroke.

Unclicking on Airbrush only switches off some airbrush related parameters,but it does not change to some other brush.The brush remains as Airbrush or in simpler words,strokes are visible as Tight Airbrush Strokes.

Conclusion is,Krita may have world's best brush editing features,but brush editing in Krita is far more complex than that in Photoshop,Artrage,etc.
Once you have habit,its really easy.

This type of brush is well suitable for product designers or car designers who want to give shadings or light effects .

If you want to save this customised brush,after clicking on autobrush button under "Brush" Dialog box,draw a stroke on a plain canvas,then simply click on Brush tip under Brush Dialog box,and then click on Custom Brush,then give a name.Adjust spacing option and then click on "Add to Presets" or "Save to Presets",whichever is visible.You may need to uninstall or reinstall you software completely.So I recomend that you save the airbrush drawn on a small canvas seperately as a photo or painting file.

For car designers and product designers,
If you are still not at all happy with the customised airbrush you created in Krita,you can create it in Sketchbook Pro or Photoshop.The airbrush in Sketchbook Pro is very different in its texture and feel,and well suitable for shading effects.You can download free student versions of Autodesk softwares by registering as a student account in Autodesk Community.It's fairly easy to get Student version of sketchbook pro though as of now.You just have to choose any college name in a particular city.When I signed up online for free student membership,that time I was not asked for student identification also.Surprisingly unlike most or all other student versions of Autodesk Softwares,I didn't found any Watermark in saved files done with or modified with Student edition of sketchbook pro.
Once you have created a brush in Sketchbook Pro,just save it as a file and open file in Krita,then just follow the instructions on:
http://youtu.be/wnol3izUXvA
(Thanks for the video Tutorial by Deevad.) :)

Wishing you Happy Car sketching :) :) :)

6)Symmetrical Mirror Painting:

You can use Symmetrical Mirror Painting in Designing exteriors.
The front and back profile of a car is mostly symmetrical with respect to its centre.

I think,Krita does have Mirror painting feature.It makes Car designing, a lot more easier.


7)Aerodynamic Design:

This attitude is wrong:
"I am car designer or product Designer,not an Aerodynamcic Enginier".
If you don't know about Aerodynamics,better you learn basics about it.Formulas are not needed,only basics.

Aerodynamic efficiency increases if the flow can pass from front over a curve.The front bonnet should be not very straight & inclined.A curve is demanded.Commonsense tells that the higher the resistance,larger the power needed to move the car and larger the fuel Consumption.
Further,a spoiler is necessary at the rear.
The air flowing from Front to back should press on the spoiler in a limited value.Otherwise,the car will swing,excessively.

In industry,enginiers are ready to work with you,only if you know some basics of Aerodynamics.
You should incorporate Aerodynamics in every design you do.

Aerodynamic designs looks attractive and awesome.
Yes,because it makes the car look like a sports car.


8)Geometry of the car:

Tall body is not accepted as a good design in a car.Cars like Suzuki WagonR are unstable and prone to accidents on hills on curves beacause they consume more torque to yaw around axis along the length of the car.

9)good knowledge of materials,used in Interiors.
Well,I think,Clay Modelling Prototyping of car design after sketches and good knowledge of materials are the only things to learn which needs big time product design or car design courses taught in Italy or France at master's level.
Most things In Car designing is based on your talent and knowledge of trends and aerodynamics.

The materials you use in Interiors should not be very explosive,should be safe against fire as far as possible.The interiors should feel good in Texture to car owner.

I think,I have allmost done with Basic tutorials in Exterior Car designing,but expect some more stuff to be added.Still Tutorials in Interior car designing is left to be done,which needs vector editing.I hope to do it soon.
:)

Hey,just look at this:
http://www.youtube.com/watch?v=_EhlaKv9Gdc

You may think that this is again conventional car designing approach by flood filling profiles first and then Airbrushing over selected areas.
Not exactly correct.
This guy doing car designs airbrushes the car profile on a new layer instead of flood fill first-Airbrush next method.
Then uses lasso tool to remove Airbrush shading on outside surfaces.
After this,the car designing artist once again uses more blackish Airbrushing on lasso selection between two arches.

Note this carefully.


Its not necessary that you use only black shading,any colour can be used.

This may be a very good technique in many cases.

Hi friends,
Krita 2.6 is out and if not best,atleast with a much much better and more precise lasso tool.

Well,as you can see the importance of precise work in car designing,
here is an precise alternative to Lasso tool:

1) I set cursor as 3D brush Model.
2)I select brush named " pixel 1" and set size (of brush) as 1.20.
I keep the brush sub type as Gausian Brush.
3)Select a new layer on a car design profile.
4) Use this pixel level brush as Lasso tool.
5)click on the alpha symbol for all below layers.
6)Make a new layer again and Click on tool described as "select a continuous area of colors."Then click on the area marked by the brush tool.
7)Delete or hide the layer on which brush was used as a lasso tool and click on the alpha mode on all below layers.
8) Finally,Paint or apply texture on the selection appeared.

Although this is a slightly a bit tedious alternative,it has an added advantage over a lasso selection:
If you save the outline of the selection as a hidden layer,you can anytime make it visible and edit the selection and once again do step 6,7 and 8.

Hi,
Everyone.
Today I will share something,many product designers and Car designers like me always as dreamt of.

Usually,people used to sketch car designs on Krita,Photoshop,TV Paint Animation and OpenCanvas,etc. and then the car design sketches would then go to 3D CAD department.
However,the most headache for car designers was canvas size limitation due to which when all car design profiles are drawn,the detailed headlamp/signal lamps ,etc designs were not possible to be created in most softwares.
Any Product design starts from an idea/Concept and I am glad that dassault systemes is the first company in the World to actually understand Product designer's problems and launch a correct Natural Sketching feature in the latest CATIA V6.
This is going to be a very big revolution.

A shuttle change in he automotive and Product design Industry.

To help car designers,CATIA V6 is been launched with 3D Natural sketching.
Wow! 3D sketching,I am sure many of you Never heard of it.

I can't ask Boudwejn to make Krita a 3D sketch software,since its beyond the scope of Krita.However this is amazing and a big breakthrough.
Various student 3D Sketching software projects include

ILoveSketching

Moderato

Rhonda

JustDrawIT
,etc.

Only Rhonda is available for free download which is too primitive to be used by Engineers and Designers and not great.

More more info,
Please see:

http://youtu.be/EF5fyCtfAfY

http://youtu.be/LApHhX3lc2k

The problem is,in Europe,CATIA V6 is as costly as VW Passat & in india,as costly as a Fiat 500 which are luxury products in India.
Plus yearly maintainace charges.Neither Student software Projects have got commercialised.I and most young designers in India cannot afford such expensive softwares.

So,I urge free Open Software community to urge these students to make these softwares freely available for those young aspiring Designers who cannot afford such expensive softwares.


With the most recent advent of 3D sketching Technology in CATIA V6,the Job of CAD department has also got very much easier.
Now they can give dimensions allmost straight away with less modifications,rather than creating the whole CAD model.This will save lot of time.
Also,Designers can now have better synchronisation/synergy between all Profile views (Front/Side/Back) automatically.
