Sometimes I'd like a feature to model an object. for example: a spiral shape around a cylinder. If you have a method to solve another personal problem, it would be nice to share.
Here is my contribution to create a screw or whatever you want with this trick: |

3 - remove the 5 simple faces of the cube. (See the line at 45 degrees) |

4 - build the section of the screw. |

5 - turn the objet of 45 degrees and select the blend tool. |

6 - make a complete rotation. (the result can be a relief or hollow). |

I've never seen this done the way you showed us. Fantastic method! |

For a screw, I usually use a profile of an AI object and lathe it.
For other things not requiring 'cuts' I use Dele's lathe method as he did in the light bulb tutorial. |

Yes,it is possible to do many things with the lathe tool, but not to rotate a AI profile wich can change during the rotation (this is not done with my exemple) .And the uv map follows the trajectory of the spiral. It may be useful.
I could show an example more appropriate to explain this.... :) |

Me too ! But my favorite model aplication goes as far as using everything including every profile imaginable and apply it as many wraps as wanted with
just a push of a button.
Plus it can even fillet that spiral with every value as you can see in the pictures.
Why on earth should I go through 7 steps now that I have all these options.
we dont need many tools for Truespace but if we have the right ones we
dont have to make so many compromises...aned think of so many alternative ways.
We have an exact idea of what we want TS to do !:D

Ok you want more blend any profile to any profile with unlimited amount
along that spiral......
the sky is the limit.....;)
its time for some nurbs tools for truespace that rock ! just some examples... |

Here´s even a painted spiral in 3d coat incuding normal map and specular map-
in 3d coat and a render..... so uv mapping isnt a problem either.. |

@Rayman "Why on earth should I go through 7 steps now that I have all these options" :
I'm not sure you have understood the purpose of my thread. :confused:
Thank for your reply but I know nurbs. I know lathe....
The goal is not to make a skrew (it was a bad example ?). it is to show original and personnal use of a tool that we know. It is not to read a manual that we know. I always see the same things and i just want to see original methods from users. (see the title of the thread). |

Marcel ! the purpose of what we are doing is to make 3d objects.
The easier it is to make things the better......
You made a screw and the intention of my post was that we are in
2009 and there are straightforeward ways of making objects
so we dont realy need very many tricks to make simple objects.
I plead for a collection of better tools rather then a collection
of tricks.....Theres not very many shapes that cant be made straight foreward including cogwheels and tracks etc.
There is no magic !
Just easy or complicated ways of doing things.....;) |

don't forget tho, there are many many ways to get to the result in 3D. there is no 'one correct' way to do something.
so please calm down. it's an interesting technique and does not deserve your comments. |

Do I sound not calm ? There´many ways of doing things right....
but to say there are easier ways of doing the same thing is valid too!:D |

Always thought the easiest way was to use paths and have trueSpace extrude along the path.
In the path library, there are already these to play with.
Might make a good project for a scripter. |

maybe it is the meaning of the word "trick" I do not understand very well. I agree for a collection of better tools.
it is a personal and original use of these tools that interests me. A way of working that is not in the manual.
taking a different way (even longer) you can discover interesting things to do. :) |

JamesMc thats exactly what I did... extrude along a path.
What Truespace lacks is to be able to fit that path exactly
to the cylinder and thats what i showed in my pictures.
The trick of folding planes isnt new at all.
One of the tutorials at the modo site shows how to make an orange juice box
that was textured and then folded with all the corners in place.....
But I reject to make a primitive cube by folding all the planes (that would be another way of doing it...;) ) but we all are used to have a tool called cube primitive :D

This is a very nice trick marcel, it's great to learn things that I don't know, and probably wouldn't have figured out by myself. :) |

sorry, I did not know that you know the cube :)
The real "trick" was the 45 degrees to do a spiral on the cylinder in a single object. It's all. |

I could see a use for this when trying to model a Steel Catenary Riser with strakes (oil industry speak)
They basically put spirals on the pipes underwater to prevent vibration and it looks like a screw-thread but not quite....lathing just doesn't cut it.... :D
Fantastic post Marcel. |

It might not be new but that doesn't meen everyone here knows about it - I've certainly not seen it before. This particular example by Marcel was intriguing for sure and may help someone approach a problem in a new way. It looked a bit 'high poly' for certain use but that's not always a problem.
I'm sure we'd all like new tools, but we haven't got them yet, so Marcel's intent - to get us to share ideas that not everyone might know - is a sensible one; as someone has sensibly pointed out, there may be several ways of approaching all those myriad tasks we try and someone might have come across a better way than us - the more we share, the more we stand to learn. Some of it we will already know, some of it may not be the best way, but some of it may be the key to solving something we're struggling with. I'd certainly like to see a lot more 'tips and tricks' especially as the 'tutorium' section is rather under-used... |

Marcels intentions behind it are good ones and its not that little trick
he showed us ... I see a problem of this forum in falling back into....
a 100 ways of doing it another way(with 10 year oldtools) ...and avoid spelling out WHAT we want the tools to look like and do.....thats the point why I get so nervous about this thread. We have talented coders and an Sdk has very deep access to the core of TS.
We got to use our time now on the development of these ... because if not
Truespace WILL be dead......
The Yafray project is a good example of how it can be avoided thanks to
our fantastic developers.
By the way using a twist is used very often in nurbs modeling to get
these kind of shapes....

Hi,
Not sitting in front of trueSpace at the moment to test this, but when you say blend tool Marcel do you mean bend tool?. Its just that it looks like model space and I thought (unless you bought it separately) there was only a blend tool in Workspace:). This of course may just expose my ignorance and then you can call me WasteofSpace..;)
PS I appreciate your desire to show the trick (and I admit I didn't know about it) and it is great to have a different perspective on using the software.
I also understand Raymans concern for the development of better tools... |
