Thanks for the help. It's more clear now.

Woodgrain, a headache for me. PLEASE, would someone explain the lexique and composition of the grain with a file like this attached.
-
I'm not exactly sure what you want to know about wood grain. Do you want to know the names for different methods of cutting? Or are you just thinking about my comment on correcting the grain direction in your model?
If it is the latter, the point is that the grain should run the long direction on the part, not across it. There are two reasons for this. First, it is usually difficult if not impossible to find boards wide enough to allow parts to be cut out across the grain. The most important reason, though, is that wood doesn't have much strength across the grain but it has a great deal of strength along the grain.
Suppose your chairs were built with the grain running across the arm rests as you show. If someone were to sit on the arm rest, they would likely break it.
If you are more interested in learning about methods of cutting logs into boards, you might want to take a look at sites like this and this for examples.

Thnx dave for your celerity.
First, I am not a woodworker, so be indulgent.
When I saw a piece of wood I am confused with the grain variation from one essence of wood to another. So, IF , I think, we modelled a log of wood in SU and then slice it we can see the grains and then grasp the structure behind.

A parliament or a boxing hall ... as you like.

It works for me. I don't know why it didn't work for you. How were you trying to extrude it?
-
Hello Dave,
With Joint Push Pull. It works for the first file and not for the second. It looks like it's me who doesn't work.
-
I just used the normal Push/Pull to do that. Joint Push/Pull is not required.
-
You're RIGHT, Dave. I did it now.
It appears that this is a straight grain. I'll do the same thing with spiral and reverse-spiral (interlocked ?). reverse-spiral is from me. Is there others type of grains?. My ambition is to recognize any part of wood by its grain. Yet it will stay a hobby. Any suggestions?
-
My suggestion would be to skip trying to draw wood gain in SketchUp. Your drawing doesn't actually show how the grain of the wood will be. It just shows the annular rings. Interlocking grain and other grain features would be very difficult to draw in SketchUp. Here's an example of a wood species that has interlocked grain.
Here's another.
If you can draw these in as SketchUp models, you'll be doing quite well.
If you want to learn about wood, and its grain, get some wood and look at it closely. Not all species create interlocking grain. Some species exhibit a wide variety of wood grain patterns. I think instead of drawing, I would search via Google for the huge amount of information that already exists.
-
"skip trying" ? For sure no.
and Thanks a LOT. -
I think I will initiate (later)a topic on wood grain. Because I have a 1000 questions about it. But not now, I am not yet bored with my chair. Any suggestions. What do you think Dave?

This arrangement is made with clf_component_stringer plugin.
Thanks Chris.

A newborn named: Larsen-Marough.
Please, I want the opinion of all pro woodworkers.thanks.
-
Well, it's red.
How do you propose to build it? how high is the seat? It looks like it would be difficult to get out of without it tipping forward.
-
Now it's green.
tipping forward: yes Dave, i've take into account this; the gravity centre i.e distribution of mass is (in theory)at the back making stability of the structure. But who knows?
Thanks to all.
-
Please, is there nice wood textures all around? I found several but all are not well grained.
Yes, grain became a obsession for me.Thanks.

You should invest some time searching the forums as it has lots of user contributions regard wood images. But this link is a good place to start.
As for the chair.....rule#1

You can go through the links here . I think you'll find some decent wood grain materials at some of those links. Arroway has some nice, high resolution wood grain images. It depends upon what you want, though. Do you want seamless or do you want extreme realism? Real wood grain isn't seamless. That will be more difficult to come up with, too.
