[Plugin] Shell
-
Ah!
Now I understand what this all is about!
You're trying to use SketchUp Solid Tools's "Outer Shell" command - instead of "Shell" which is this plugin. I can see how you got confused.
-
Aha!
His video shows him trying to use [Outer] Shell on a non-solid object !

mr TIG, thanks you for your reponse but i dont know how to make any form to solid form with sketchup, can you make video tutorial for this plugin plzzz

No.
If you do not grasp the concept of what a solid is how would showing you help?
Most simple forms made by Sketchup like boxes and cylinders are 'solids'.
When you add them together they can make internal partitions etc which need removing before it's considered to be a solid.
Try my SolidSolver tool which attempts to turn non-solid groups into solids...
However, your example of a 4 sided box could never be made a solid unless you add more faces/edge etc... -
But he doesn't need a solid at all. He simply confused the "Outer Shell" menu item for my "Shell" menu item.

thanks
i confused the out shell with shell
your plugin work perfect nowthanks thomthom and thanks TIG too

Great plugin, already works well for 0.2!
-
This is really useful.
Thank you so much. -
Thanks, i'm looking for something like this.
-
Thanks Thomas, this plugin is very useful!
However, I don't seem to be able to commit after typing a thickness.
The shell is generated, but neither double-clicking or Return finishes off the process.
The space tab brings me back to the selection tool, but the already generated shell is lost.

Got a sample model?
The plugin is a very early experiment - so very prone to errors.
-
Thomas, my apologies for having bothered you without testing more thoroughly beforehand!
Although the error is reproducable, it is limited to geometry that has rounded corners in combination with an offset of the shell, that is close to or greater than the offset of the rounded corners.
I have attached a sample model with some tests - the red shape produces the error.

In case you haven't tried it, Fredo's Join Push Pull is more mature and does a better job.

This issue is the same as the 2d offset when you get reversed edges in the internal offset loop on tight corners or narrow peninsulas.
I have an unpublished version of some 'smart_offset' code that spots this issue and offsets in 2d 'truly', ignoring these glitches... I might dust that off...
In the 3d equivalent - like 'shell' - we need a similar 'reversed faces' catcher.
Perhaps we make the internal 'shell' faces, then intersect everything in its group with its entities, to 'split-off' any 'crossovers', then we erase any faces that when raytested from their center by their normal hit the parent object's entities, finally erasing all single faced edges that are left over and any unfaced edges left after that...Just some ideas...

I pull and click or enter the distance and click but it never completes... allows me to choose again and again.
works on simpler mesh though. like box and sphere. wondering if it's my mesh that's the problem.
it shows me the preview of what will be made. never makes it. I wonder if there is another way to complete other than double click?

Does the Ruby Console display any error.
It it quite likely to be bugged - it's a very early experimental version.

What a bomb "shell" Thomthom. Thank you very much for this beta that is already a great plugin.
I've been long waiting in the shadows, looking for a way to make myself useful around here. And if you don't mind, as I'm no coder I offer myself as a crash test dummie. I made some observations too and I hope you may be able to take some conclusions from them.
1 - As was already mentioned before, I noticed that with some geometry the preview is being shown but the shell isn't created with double click or enter. In my case It usually happens when the preview draws extra faces that intersect the original group/component's faces, getting outside. Besides that the preview is accurate. (If there was already a way to force the previewed geometry to become real geometry, this could be an awesome plugin.)
2 - This preview geometry thing is more prone to happening with closed or revolved shapes. Sometimes It works but creates strange intersections inside. If those faces are open and the shell isn't too deep, it works just fine and it's also very fast. When it does work it is flawless with all faces parallel and at the same distance from each other! I made some (almost) manual shells, just to compare and they were always perfect matches.
3 - I also tried negative shelling just to test if I could get the same shape back. When tt_shell works, the negative shell also works. I also noticed that once I inserted the negative value, SU remembered that direction as being positive. So if I wanted to make a "regular" shell after, I had to input a negative value again.
4 - In the file below there is an example of an object that did not create a shell but got some interesting results:
a) I tried creating a 30cm shell and it failed.
b) I created the shell above using Normal Push Pull and the usual intersect faces method. I got the resulting 30cm shell I wanted.
c) From this resulting shape I tried using the plugin to create a second 30cm shell and it worked, wich I found strange.
d) So I tried to make a negative shell wich would grow the shape back 30cm. This again worked and I was back with the shape I got in b).
e) I picked back the smallest shell from c) and I tried to make it grow 60cm so I could have the initial shape in a). It failed to do so.
f) I tried again, but with a 59cm value and it worked.
g) I noticed that there were some edges that were very small and that if I would have tried to reuse the 60cm value that I did before, they would become vertices.What this suggests me is that maybe the plugin isn't able to manage edges that shrink until they become vertices. The reverse should also be true and that means the plugin also can't handle vertices that must grow into edges. Of course I'm not absolutely sure but probably there's something down this line.
This is all illustrated in the scenes from the attached file.
If it is ok I'll keep testing the plugin until I find some more examples of this.
I really hope I made a small contribution and thank you again for all the hard work. It's much appreciated.
