@surfmike In case you're dealing with tiny objects in your model, you need to adjust some world parameters. For your model, changing gravity to -1.0 and setting world scale to 20 prevents the penetration.
Group the joint with object A worked out way better. Thanks.
However the other "sink into ground" issue still remains.
Do I have the right settings?Also the test file "curvy_joints.skp" have the same issue...
-
How about you try setting material thickness to 1.0. Maybe that will prevent the issue. In Newton, there is always fraction al penetration however you can adjust world properties to minimize it.
-
Nope, material thickness 1.0 made it even worse. The objects also started shattering...
-
Thanks Anton, that did produce an error, though I don't understand it.
Here is what it gave me:Error; #<NoMethodError; undefined method `solver_model=' for #<MSPhysics;;World;0x0000001036bf18 @address=287093504>> C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;2632;in `activate' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;27;in `select_tool' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;27;in `start' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/main.rb;575;in `block in <top (required)>' SketchUp;1;in `call' Error; #<NoMethodError; undefined method `valid?' for #<MSPhysics;;World;0x0000001036bf18 @address=287093504>> C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;3181;in `getExtents' Error; #<NoMethodError; undefined method `valid?' for #<MSPhysics;;World;0x0000001036bf18 @address=287093504>> C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;2761;in `deactivate' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;35;in `select_tool' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;35;in `reset' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;2164;in `abort' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;2148;in `rescue in call_event' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;2141;in `call_event' C;/Users/Chris/Dropbox/Sketchup Stuff/Plugins/MSPhysics/simulation.rb;2948;in `onMouseMove'
Thanks for looking at this!
Never mind.... It was idiot error! I had installed it through Sketucation AND through the Ext Warehouse and that was causing the problem.
Thanks again!

Sutfmike does that happen to the sample model you posted here?
-
Anton_S, yes it does, also the same happens in the "curvy_joints.skp" file as well.
We're talking of a minor sag, but still... -
Surfmike, one last thing I can recommend is changed solver model to 64 passes.
-
A new version 0.9.4 in the first post but I can not find any information about what has been changed...?
-
I recently saw a IKEA presentation where they used a custom plugin in Max for placing things more naturally. It had no setup if I'm not mistaken.
Would it be possible for a quick use mode where you with minimal input could simulate things like pens in a mug or stacked items like plates, books and such?
The key word is "minimal input" for quick, one time simulations like the above examples. -
Faust, I fixed the friction bug and improved start performamce witb joints in this, 0.9.4, version . However, I did break some things in the dialog. So I guess you're going to have to wait till next week for the fix.
Pixero, that's interesting. At the moment there is no simple way of simulating for siref groups till they stop, however, I added this to the list.
-
Here is some more info on IKEA's "earthquake" plugin:
http://vimeo.com/163789781It starts approx 23 minutes in but the whole video is very interesting to watch.
Martin says in the comments:
"The physics simulation is using a physics engine and is a plugin. Only one button setup. All hidden geometry is not used. All non selected will be unyeilding and all selected gets hardbody physics properties."Something like this would be very useful in SketchUp.
-
Not new - but SketchUp + MSPhysics. The rendered version looks much better...
Time: Modelling and MSPhysics 0,5 h; Layout and GIF-Output for this post 1,5 h (max. 2 MB)...
Edit: + a quick indigo render frame...

hello
how to change the color of a solid?I tried :
onStart{
@box = simulation.find_body_by_name("box")
or
@box = simulation.find_group_by_name("box")
}onUpdate{
if key("up") == 1
@box.material.color = [0, 255, 0]
Else
@box.material.color = [255, 255, 255]
end

Hi, select the Paint Bucket and add material to group and try again.
-
Pixero, I'm working on that feature.
Faust, that's a stunning piece of animation!
SynSuka3d, like Istvan implied, you can add material to group prior to changing its color. You can also do it with script, in case the group doesn't have a material associated with it. However, if the inner faces are already colored by a different material, you must decolor them to default material, both front and back faces, so that the group's top level material is able to color them.
Note that the object that contains the script should be part of simulation, that is not ignored; otherwise, the script of that object won't execute.
Now, to answer your question, if the script is associated within the body you're coloring, you can have
@box = this.group
. Otherwise, it should be@box = simulation.find_group_by_name("box")
. Note that the name is case sensitive and considers all the blank spaces. Anyway, here is the script containing it all:onStart{ @box = simulation.find_group_by_name("box") # Add material to the box in case the box has no material. if @box.material.nil? mat = Sketchup.active_model.materials.add("BoxMaterial") @box.material = mat mat.color = [255,255,255] # optional end # Record starting color, just so we can reset it in the end @starting_color = @box.material.color # Utilize 'flag' variable to avoid coloring group the same color multiple times. # Just for optimization purpoposes... @flag = nil } onUpdate{ if key("up") == 1 if @flag != 1 @box.material.color = [0, 255, 0] @flag = 1 end elsif @flag == 1 @box.material.color = [255, 255, 255] @flag = 0 end } onEnd { # Reset color (also optional). @box.material.color = @starting_color }

Thank you Anton_S
Good !!!manage transparency of objects ?
alpha ? scriptEnvoyé de mon PRO 5 en utilisant Tapatalk
-
SynSuka3D, to change opacity, you have to utilize the material's alpha function: http://www.sketchup.com/intl/en/developer/docs/ourdoc/material#alpha=. For your model it would look like this:
@box.material.alpha = 0.5
or any other alpha ranging from 0.0 (transparent) to 1.0 (opaque). -
I have a bug to report, maybe. I've noticed that if you use programmed ratios for things, such as gear reduction, if you leave objects as default (where they can sleep when still) you can cause things to sort of slip, and lose sync with each other. (example: gear teeth phase into each other)
The only way to stop this seems to be to make them never sleep. Is this behaving as intended?
I also have a file that causes crashes when I try to make a door work, but it seems to have stopped doing it. I will attempt to re-create the bug and post the file here.

Announcing version 0.9.5!
This version comes with more compatibility with Mac OS X. Now keyboard input and MIDI work on Mac OS X too. Also, a few new features were added, such as another play button, along with plenty of fixes, upgrades, and improvements. Check out the ChangeLog for more information. -
Hi. Hope you can help as I'm unable to get past an install error on Windows (64 bit machine). I'm using Sketchup Pro 2015 and attempting to install on a device connected to a workplace network which I think is the cause of the problem. I can install it successfully on a separate standalone (at home) laptop. I am installing with network administrator rights.
Having installed both the ams library v3.4.0 and ms physics v0.9.5 through the sketchucation plugin store button within sketchup, they both give confirmation messages that they have successfully installed. They both appear in the window>preferences>extensions list and are checked. At this point no toolbars are available, so I restart sketchup. I then receive this message...
