im trying to push down a curved surface but can't get the desired effect , my shape get slivered on the edges. and i have to delete lots of curved faces one by one. how should i decrease the thickness of solid the way a normal flat solid would work?

Joint Push/Pull is working normally. It just pushes all the faces in the direction of their normals which will leave those faces.
For something like your example I would either draw a curved face where you want the new surface to be, intersect it with the existing geometry and then erase what I don't want or I would draw a 3D shape and use the Solid tools to subtract the stuff I don't want.
Inspecting mirrors is a job I could easily see myself doing.
3 out 4 people make up 75% of the population.
solid tools and booltools often don't work since we have little hole in our geometry. so they don't get qualified as a solid. Intersecting faces is an untidy and a bit long way.

I'm trying to extrude a multitude of faces with the same kind of behavior than the jointpushpull plugin. My concern is that I need as many solids than faces as a result.
If I jointpushpull 5 adjacent faces, they will end in a single extruded group. What I would like is having 5 adjacent solids as a result.
The ky Group PushPull 2D Faces plugin does that very well... it found out to be the best solution for me make in making that sketchyphysics video : http://youtu.be/v9jWE1aoueA
BUT for this video the faces were all parallel. What I didn't find yet is a way to obtain the same result (multiple adjacent solids) when the faces are NOT parallel. The ky Group PushPull 2D Faces plugin actually does it, but the groups all interpenetrate, which does not end with solids, which is not ok with sketchyphysics...
My point is I would like to extrude this wonderful head model by 3D creator (http://sketchup.google.com/3dwarehouse/details?mid=d34e5f52b8698e0e72879169b6bea9fb&prevstart=0) into multiple solids, then use it in sketchyphysics (if my iMac accepts to deal with sio many entities...)
Any idea ?
Thank you for your answer, and congratulations for the great job you do with all these plugins.
I tried what you suggest, but as a result I have one group, and I would like to have 5 different groups / solids>
Joint is an image of what I get.
Can you think of a way to do it ?
Once you have made the 6 'segments' [it's not 5?], you can edit the resultant group.
Use Select 'by fence' so that only the edges/faces of a required 'segment' are selected and then 'group' them.
Any shared edges with non-selected faces are duplicated automatically.
Repeat until all 'segments' are groups.
Now edit each segment-group in turn.
Over-draw an edge bounding any missing faces [e.g. at junctions], these faces should then reform...
Tip: to see what you are doing set your View > Component-Edit to 'hide-rest-of-model'.
Now you should have the main [original] group containing 6 solid sub-groups.
If you want them 'loose' you can just Explode the original group...
thanks for your answer.
The problem is I have 6500 groups on that model !
I couldn't treat them individually...
Do you think there is an automated way to do it ?
On the image below, I used Ky,'s Group and Pushpull 2d faces to extrude a few faces as groups. But the groups interpenetrate, which is unsuitable for sketchyphysics (this is my guess, but I could be wrong —I discovered all these great plugins you guys make just a few days ago...)
I could use the SU feature Solid Tools >Trim, that would do the trick, but this tool seems to apply only on two solids, which is not enough... (again, I could be wrong on that point...)
On the other image I used Joint Push Pull
Would you have any more idea ?
The purpose of all this is being able to "play" with such a model in sketchyphysics (collapse, explode, etc...)
I think (am I right ?) that it has to be separate groups in order to do so...
If the groups interpenetrate, the sketchyphysics contextual menu or dialog box will not unfreeze the groups. Do you think it's true ? Or am I making a problem where there is not ?
Thanks again for your patience
Awesome tool. Works great most of the time, but i am getting a crash attempting to JPP the surface in this attached file.
Indeed, it does bug splat.
After a rapid check, it seems that the configuration with those holes and concave sides of faces is precisely one case that I left for future implementation.
I suggest you cut the big face into smaller chunk with vertical lines. Then it works.
Sorry for inconvenience
I've got some problems about Joint Push Pull - v2.0b: I followed all the steps for the installation, but when I open the program a window appears and says "Error Loading File jointpushpull_main.rb undefined method `get_last_state' for nil:NilClass".
Fredo6, what does it mean?
Thanks a lot!
Ps: I have Google Sketchup 8 pro...
With the visual edition, you have a preview mode and you can type the offset in the VCB. The dialog box can be invoked by pressing TAB or via the contextual menu.
What is exactly the option "Thickening" against the normal use ?
Can you put a little image before/ after

Is beautiful that please without concept!
I try to use the plugin to create a skin within an angular 3D model.
It gives some trouble at a point where 6 edges intersect. The plugin creates a new point, after averaging all 6 normals to the faces, but keeps the edges together. I would like to see a result where new lines are created and previously horizontal or vertical edges stay hor/vert.
Is this plugin or another plugin/function in SketchUp able to do this in a single operation or do I have to adjust it all by hand?
I installed this tool months ago, but only just realized what it does. Another great plugin from Fredo6. Thank you.
I read through the suport literature and cannot repeat something I'm seeing there: According to the support document, if my neighboring face normals are less than the angle of influince from the target face normal, the they will influince the targets offset. Correct? I tried to re-create what was shown on page 13 & 14 of the document, but my model seems unaffected by angle of influince. Did this functionality go away in later versions, or am I mis-interpreting something?
In your image, did that one face not extrude in a multiface selection and extrusion? Occasionally, this may happen, or it seems it has happened with me. Maybe the selection was made appropriately, but that face was spontaneously deselected?
In this simple example, you obviously could construct the missing portion by using JPP by normal or by vector, or even draw the completion with the pencil tool. In a more complex example, any of these corrections could get tedious.
I take the slow, deliberate approach in my aimless wandering.
I think OP is looking at how the angle at the sides of the extrusions are normal to the extruded face and not influenced by the angle of the adjacent face.
It has been a while since I did this similar operation (the faces on the left). As I recall (and I probably have that file) the edge faces did angle outward and not come out square. I can't repeat this now myself...so, good question.
pbacot is correct. I've attached the relevant portion of Fredo6's support document to make the point clearer. In attempting to reproduce his example, I find that no matter what the angle of influence is, I only get the results of the Fredo's middle image. That is, extrusions next to deselected faces are normal. pbacot, you said this feature worked before. I wonder if your file was done with a previous version of JPP? I grant you the support doc is now 4 years old.
This script is very close to doing exactly what I need, and I'm hoping somebody might help me figure out how to take it the rest of the way... I'm trying to take roof systems that are drawn as single-faces, and then vector push them vertically into their proper thickness. JPP works fine for this, but it ends up with vertical hidden lines between the upper and lower face, which make it messy to turn the final roof into a solid, which is necessary for further editing. Outside of going through the complex roof form and deleting or filling-in every hidden edge, is there a way that vector push pull can just make a standard solid geometry?
Since JPP 2.0, the angle of influence is not used any longer (see release note).
I don't remember why I had to suppress this.
I'll try to have a look at the code to see if I can re-stablish it
