Blender question and answer thread

[cwbolton]

Hello people im fairly new here i am a 3d modler using blender and i notched there are hardly any blender threads and most of them are poeple asking for help

Hence the making of this thread if anyone has any blender problems or needs help or just wants to ask a question such as "what is the best rendering engine" or even "what will your next project be cwbolton" im here to help and will give you a fast answer so anything no matter how noobish your question maybe you will recieve no criticism from me as i rememer what it wasl iek being a noob asking a question such as "what the heck is RMB" right mouse button obviously so anything at all dont hesitate to ask

Happy to help
Chris

Welcome to SMCars, I hope you'll enjoy your stay here.

It's nice to see yet another Blender user here. Don't forget to post your projects to the WIP section as soon as possible !

About your idea of dedicating a thread to Blender questions & answers, there is already a whole section for Blender related discussion : Q&A, tips, iinteresting ressources or whatever one can think about something worth posting.

So you should stay tuned on the "New posts" links to keep tracking all the posts incoming about Blender. I'm sure you'll soon discover the traffic about it is not that huge

Hi,

I'm fairly new in blender, I usually use Max at the office. can you tell me where can i find extrude edge tool(Max) in Blender. These Tool can accelerate my Modeling Speed I'll be so ready in production if I can find these tool in Blender.

Use EKEY when you have some vertices / edges / faces selected, in Edit Mode.

[cwbolton]

yes simply select your vertices and press the e key and extrude region then move your mouse button also hold the ctrl button so snap it to a grid and also if your push e then extrude region you can then push x, y or z to move it along tthat axis

[tom120934]

And to be almost complete, once you entered X or Y or Z using keyboard to specify along which direction the selection should be extruded, you can enter the length of the extrusion with the numpad. E.g. : type "3", ".", "0" and "4" to extrude by 3.04 Blender units.

Pressing once X (or Y or Z) will extrude along global X axis. Pressing twice will extrude along local axis. Pressing a third time will cancel axis selection.

I hope we were clear

ah yes thank you for pointing that out also 1 blender unit is you know that grid when your in top front or side view well 1 box is 1 blender unit so putting extrude along the X axis then put 1 it will extrude it along the x axis 1 blender unit you can go into real detail and extrude objects to like 1.3521 along the x axis for precise detailed models also ive heared somehwere that 1 blender unit is 512px x 512px

hope we could help

For precision modeling, the shortest advice is : define yourself the scale you'll be using for your model. For example, I've always used "1 Blender unit stands for 1 meter". So any precision like, e.g., a 5 mm gap between 2 body parts on a car is reachable : it's just, for that example, a matter of 0.005 Blender unit.

For a longer advice, one top level reading is the book from Robert Burke. He was published in BlenderArt some issues ago, and the book is a longer version of his works. There was a new on Blendernation about it : Precision Modelling PDF Guide at BlenderNation. The guide is available on his site : rab3D Home

About the native pixel resolution of Blender, it's (as far as I know) only used for background texture, and the resolution is 512 pixels for 2 blender units (with a zoom factor of 1.0) Such background textures may be used for blueprints, however I always used a different way of handling them : please see my website about it, as I've wrote a tutorial about it, Pixels or Atoms ?.

Why ? Because I don't like to resize the blueprint with Gimp (or any other software) and I also want to use, as a modeling canvas, the actual dimensions of the car I'm working on. Length / width / height of course, but also wheelbase, tracks and tires dimensions like width, rim radius, sidewall height.

ahh i see well i hope we answerd your question with our extensive answers

also tom check your pm's

[bobi_chen]

well, thanks for your explanation, really explained a lot of things in Blender . but I'm afraid its still don't answer my question :? . Does anyone here have experience using Max edge extrude tool?
I'll show you why i need this tool.




Number 1 is just smoothing without any bevel
Number 2 is beveled 1
Number 3 is with only adding 2 loop cut and slide the edge near to the each corner.
Number 4 is beveled 2 recursive

Number 3 is actually what i called "edge extrude tool" in Max (the height is "0"). it produced the crease shiny effect for the in game(real time) shader, with only few polygons. Number 4 Show the same effect at the edges but need more polygons to produced. the subsurfed version produced the similar result for number 3 and 4.

This techniques is often used for "Car Low Poly Modeling" for Game.

Well actually I can get the" edge extrude" manually by Loop cut/knife and edge slide, but it won't give the same width for every crease shiny effect.

right now i am trying to modify the bevel center script, to get this edge extrude tool. it will take longer time since i never learn about math process for 3D.

I'm really grateful if i can get help from programmer. Any suggestion guys?
