T-square and the compass

Euclid 300 BC: The Euclidean geometry is the geometry of lines and circles. The Euclid intuition was that any number could be built with the help of these two instruments.

T-square and the compass were the only tools for architecs along more than 1500 years. very few measuring tools was available: rope knots and what else along those times.Elsewhere, units was varying greatly from one region to another. So construct a drawing was consisting, not report measurments but in dividing lines in segments, and reports segments with compass.

The compass was, during this infinite laps of time, the mystic instrument throwing up a bridge between human being and the divine. It knowledge was kept jalously and its secrets only learned from master to disciple..

Ruler and Compass Constructions by Ken Brakke

I believe that: one time the first grid was drawn, in matter to define the elemental unit of the drawing,in fact the radius of the elemental circle, the compas was fixed for the all work. And everything was drawn with this value. This way was very opérative for the construction itself because each point could be report with a rope knots as real radius measurement decided at the begining.
I believe also that secret construction points was left in the construction in order to let workers follows themselves in time. A cathedral construction was during easily 100years...

Cher Matt!

Bravo pour cet outil!

I agree completely with Gaieus: a seemingly "little" tool that we forget that we need all the time.

How could we do without this tool ??

[flash=550,412:2xppaall]http://www.youtube.com/v/aEBrzJscSP0&hl=fr&fs=1[/flash:2xppaall]

But at the end we need to erase all those construction points!!!
No problem! Just use the so powerful Matt666's Selection Manager

And dear Matt I'm sure you will not be angry about me if i complete the panoply with those daily other useful tools:
Jim Foltz's Construction Line Tool
Jim Foltz's Arc Centerpoint
Todd Burch's CenterPoint
Didier Bur's fr_lines_converter

Simon

A piece of life, I love it! simon

Boolean tool works on closed volumes indeed.

Here is a Navajo pottery

.
Construction Line Tool
Selection Toys (1.5.1)
BezierSpline v1.21
Projection toolbar
Tools On Surface - v1.3
Mirror_31
BoolTools

Alternate solutions:
One to isolate the quarter, and two to paint the bowl.

I'm a bit satisfied (by myself ) to have found this lighter second solution to isolate the quarter. Because Section Plane Tool is rarely used and often forgotten
Thank you

for your too much good SectionCutFace v2.0

The other way to paint the Bowl is not really new, but it's pleasant to show how we can play with Components.
Thank you

for your too much good Mirror_31.rb

If you desire to play with it: PotterSC_S&S_SCF.skp

Hi Gaieus
Using UVTools to "paint" my Bowl, is I think an excellent idea. I have totaly forget it, but also have never use it. So i keep it in mind and will try something later.

@unknownuser said:

For the BoolTools, you'd probably have to "close" the empty sides of the quarter shapes.

I had already tried this but it seems it is the Bowl itself which need to be closed. And I have to find how i can do it, and undo !

( Subdivide & Smooth , BoolTools, UVTools, Whaat's shadow is all over this thread )

thanks to you nomeradona for this fresh word

I have tried to find out how to paint this S&S Bowl. (lot of tries believe me). It is not simple because S&S shapes are based on square, not on circle. And if we don't want to paint by hand the overall indian pot, we have to use the sectors solution (see VoderVocoder solution). In our case, the minimum sector is a quarter.

Here is the first pair of solutions. One solution to isolate the quarter,+ one to paint the bowl.
(tomorrow (i hope) the second pair )

Comment1:
I have tried boolean tools to isolate the quarter bowl from the crossed panel: Boolean--OSCoolean , BoolTools just released without success. the shape seems to be not a "valid solid"

comment2:
Rotate and copy the quarter needs great accuracy: i have missed it for a while

plugins used:
Construction Line Tool by Jim
Projection toolbar by Didier Bur

simon, still walking on this tutorials trek

Hi Matt,
Hip Hip! I've just installed your plug v 1.2 and it seems working very well (all tools are seemingly supported)! So cool!!
It's too young to see if it remain operative on duration, but i believe this is now fixed.

Many thanks for that tool dear Matt

I take it!

simon.

Thanks Solo for this friendly post which freeing my mind.

@unknownuser said:

I bet in a year from now creating the same bowl/vase will be even easier with a tool we have not seen yet.

I think my set of simple indian bowls is a good exercise to introduce new modelling plugins and to show what they potentially are able to do.

++ simon.

Come on Guys,
No good Tip added, no alternative process suggested, no remark on where I'm wrong, no companions to follow me in this "tutorials trail". Do you think I'm making this heavy work for some individual glory? I make it for you, dear-to-my-heart community. To accomplish something in a participative way.. I'm tired to work on the wind.

And if you need a spiral line angled as you whish: "No Problem "

it's always me

Snippet pasted from Shaping a cylinder - interesting technique about the "fifteen degrees rotation" needed to achieve the spiral.

personal asking:
Why only a 15° disc rotation allows copy of ring angled edges to fit with the source, whatever the height is?


.

Ecuadorian answer:
360º (full circle) / 24 sides in circle (SketchUp default) = 15º

If you want to use a 10º degree rotation you need to start with 36 sides in the circle.

If you want to do it with 20º, you need an 18-sided circle.

Solution during the night:
I was thinking of this in the very morning before wake! And i've find this is not something of "big theory" as I thought, but something pretty simple

Monday, March 2nd.
After months I come back on this thread.

First, it's because the illuminating and simple Voder Vocoder's solution isn't available anymore on DataFileHost.

Secondly because since the end of this first part thread, fantastic tools had been developped by some (wellknown) especially tallented Ruby Makers. An important part of those tools leads to allow SketchUp to be a modelling engine.

so Here is my PoorFlatEllipsoidIndian Bowl made with: SubdivideAndSmooth v.1.00 _ by Dale Martens (Whaat)
(I must say i'm not at all specialized with S&S. It is not an easy set of tools. I must confess that when after a while, i want use it again, i must go back to see the video tuts 1 & 2 again and again . But, but, little a little i find solutions to obtain what i want!! )(So for asking help, you can face up to our great masters as: Solo, Teezer, Boofredlay, Kwistenbiebel, Mariocha,.. sorry for those I forget or ignore)

Due to the intensive manipulations, we are driven to make a lot of small mistakes. Most of them they come from Move tool. This is problematic when we want to paint and modify the object.

Here is cases of twisted rings.

So here is a second method, yes less fun but more robust:

Secondly i have missed to explore a modeling way which makes school inside SU. It is certainly not the easiest way nor time saving one. But it is a fresh handmade way.

Gaieus, "../but I do like them for sure.
There is many advantages to use Viddler: great picture quality, easy upload, nice statistics, Flash or original downloads, video comments, good sharing options,... Nothing is perfect, the streaming is a bit erratic So I now put direct link systematically just below .

I have made a mistake at the end of my previous second video, PaintingTheBowl_B.
In order to reconstruct my Bowl, I have copied the single slice x49 (Cause my starting stripped tube was based on a 50 segments circle) (i had been surprise by the enormous time this operation had taken )
In fact i had forgotten this supposed "single slice" was already made with a couple of slices (mirrored). So, it was only necessary to copy it by 24 !!
