BasicsWhen you run Sketchup you should see several new tool bars. If you don't see the toolbars go to View->Tool Bars and turn on all the Sketchy ones. This is the main tool bar The three buttons are Play/pause,reset and UI.
Load one of the examples and press the play button on the toolbar. You should see the scene animate. Dragging
CreatingAny group can be a physics object. But the physics engine can only simulate certian types of shapes. Those shapes or "primitives" are box,sphere,cylinder,capsule,chamfered cylinder and convex hull. This isnt as limiting as it sounds because you can combine those simple primitives into far more complex shapes. Primitives tool barThe easiest way to create a physics object is to use the SketchySolids tool bar.
Load one of the examples and try adding a few primitives to see how they react. Notice how the primitives can be built on top of each other. BoxFastest and most flexible of the primitives. Can be scaled in any direction. SphereCan be scaled in any direction. CylinderCan only be scaled uniformly or non-uniformly in the up/down direction. You cant "squash" the cone. ConeCan only be scaled uniformly or non-uniformly in the up/down direction. You cant "squash" the cylinder. Capsule/chamferCan only be scaled uniformly. FloorThe last primitive (the gray one) is a "floor" you usually only add one per scene. It gives the objects something to land on. If you dont have a floor the objects will just fall. Scaling may cause unpredictable behavior. Convex HullUsed when none of the existing primitives will do. Made by right clicking a group. Group must contain only faces (no sub groups) The shape is a "shrink wrapped" version of the mesh. Here is a very detailed explanation of what a convex hull is: http://www.rustycode.com/tutorials/convex.html Scaling may cause unpredictable behavior. Static MeshActs as the non moving part of a scene. Can be almost any arbitrary mesh but it cannot move. Made by right clicking a group. Group must contain only faces (no sub groups) Scaling may cause unpredictable behavior. Object attributesRight click an object to set its attributes. FrozenObject will not move until touched by another object. Very handy when setting up scenes. StaticObject will act solid and unmovable IgnoreObject will be ignored. Used to keep an object from having collision. Not quite the same as NoCollision NoCollisionObject wont collide with anything. Doesn't work yet. EmbededGeometryNot used anymore. Will be removed Joints
Hinge is like a door hinge. But it can also be a wheel. Hinge is the joint you will use most often. Slider allows the object to move like its on a rail. Corkscrew is a combination hinge and slider Spring is like a slider but the object will try to "spring" back to its original position Universal joint is like 2 hinges at right angles to one another. This joint can become unstable and fly appart if moved to fast. Ball joint will allow an object to move freely around a single point. This joint is also unstable if moved too fast. Joint connectorThe joint connector tool is used to connect and disconnect objects from joints. Example
You can connect joints to multiple objects by selecting the joint first, then selecting each of the objects in turn. You can connect connect a object to multiple joints (rarely done) by selecting the object first and then the joints. Joint attributesIf you right click a joint you can edit its joint settings. Each type of joint has its own settings. Hinge
Slider
Spring
Compound objectsYou can group 2 or more objects to make a compound object. This means that the objects will move together as if they are attached. If you made a table out of 5 boxes (4 legs and a top) then started the simulation the table will fall appart as soon as something bumped it. If you group them they will behave like a table. Grouping jointsJoints can be grouped with other objects. Because this allows the joint to move it allows you to make more complex machines. NOTE: You can only connect objects to joints that are only one layer deep inside a group. <more to follow> Bugs and known issues
Future work

I am floored!
Sketchup is the ultimate app now...hands down
Great work guys.
this makes SketchUp? all that i dreamed it could be!!! keep up the good work, a few bugs kinked out and you are gods amongst insects. i have stayed up for hours making all sorts of little gizmos, like a domino chain that stretched into eternity!!!

Whenever I hit the "play" button, sketchup gives me a "bugsplat" message, then crashes. This never happened before, can anybody help? please.

I had this great little program working nicely yesterday and now I can't get the shapes to drop with the play button. Nothing is moveable. Am I doing something wrong?

Oh my God - you just killed Autodesk Inventor!!
Oh my God - you just killed Autodesk Inventor!!
Guys...how do I actually post an animation online?...how the heck did you guys do it?!!! I want a slice of the pie.
How do i install the plug in?
WOWOWOWOWOWOWOWOWOWOW!
thanks for all your help, it's amazing now.
i am going to build www.wolffaerocycle.com already did the aero work in x-plane
Is there somekind of limitation ?
When I animate some objects, they all stop moveing when they are moved away from the center of the scene.
Thanks for this funny playtoy :-) Jorgensen
there are limitations though... You can't make things too small or too big
and if you throw something far from the center the object will freeze
It's great... but hard to use. Don't forget you need google sketchup not the other one to use this.
Could someone please update this page with the current set of joints, functions and tips? The QuickReference? card as well.
what about the universal, the screw and the ball, what do these joints do?
does anyone know how to install sketchyphysics 2 some one plz tell. write back....
How to modify objects mass? Thanks.
How Do You Install It???
What version of sketchup do you need to use it????????????
hey thanks for making sketchyphysics.. though its still undergoing betta testing. i think i would like to see a nicer GUI.or icons interface for the plugin(though that would be the least of worries for now :) )
GOOD JOB
Whenever I hit the "play" button, sketchup gives me a "bugsplat" message, then crashes. This never happened before, can anybody help?
This is awesome!
I have a few questions.
First, how do you resize a floor? For that matter, can an ordinary box act as a floor?
Second, I attached two objects to a hinge. However, only one of them will move when the hinge is set to act like a motor, and the other one starts moving only when the first one spins around and bumps into the second one. Thereafter they both spin, but remain in constant contact. What am I doing wrong?
Third, is there a way to tell a hinge/motor not to have a maximum angle? I'm just using really large values (like 1000000) for that purpose, but I'm worried that doing so might have a performance impact.
Fourth, is there a way to tell an object (a freely-moving object) that it has momentum in a particular direction? I'd like this so that when I hit the "play" button, a particular object starts moving immediately. I could always create a motor to swing something at it and "kick" it per se, but that seems somewhat combersome.
Fifth, I'm having a problem where objects that are moved away from the center freeze (during simulation), and not even dragging will get them back. The only way to get them back is to reset the simulation. Is there a solution to this?
Other than those questions, this is an amazing tool!
here are some answers to your questions javawiz.
1)You can't resize a floor, but you can copy and paste lots of floors.
2)This may just be a glitch. I would suggest grouping the two objects together by selecting them, right-clicking and press 'make group'.
3)There is. Just don't put any number in the box.
4)You do know that you can drag objects when you play the simutlation. just click on it and drag it.
5)This is a limitation. The program has a limit to the distance away from the center point. So there is no solution to this.
I hope this was helpful!
This needs to be updated for the new SketchyPhysics 3(alpha) version! We need some instructions on the new keyboard use.
when i hit the play button the model i downloaded falls and breaks apart, can anyone HELP.
Anyone new to this app go here and all is explained....follow every tutorial to get the best results and to understand how it works.....it will save you hours of frustration :-) believe me! http://sketchyphysicstutorial.googlepages.com/home
How do i control stuff with the keyboard? Please reply. Thanks!
Very great thing! Unfortunately could not find a way to program the behavior of objects in the simulation. Need a scripting language, with which we could do animation. Another would be not bad to create entity "Sensor". Its purpose is to find objects (groups) around itself and measuring distances to these objects. People who are involved in robotics would be very grateful.
Whenever I hit the "play" button, sketchup gives me a "bugsplat" message, then crashes. seems like other people had the same problem too, not sure if anyone could find a solution for this. any suggestions?!
I dont see the motor, piston, gyro tools in my sketchy physics toolbar. Can someone please help.?
So I am using SP3x now, and trying to edit joint settings, but nothing shows up when I right click, and select "joint settings". Shouldn't there be like a pop-up box or something like that? I am using Windows Vista home basic OS if this helps. I would like to get on with using the new version without the hangups. Thanks! brandonp1ster@gmail.com if you have any suggestions...
it's great, through some experimenting and tutorial viewing, i found out how to do a fair deal. problem, sometimes the physics shape, in particular cylinder, is horizontal, when i want to rotate the part along the horizontal axis, i get big bumps, is there no way to change the orientation of the physics shape? perhaps set it to a shape that's attached to the joint that is individually modifiable? as is, i can sometimes twiddle it to the right orientation, but not always.
Does this plugin support the collada export? (collada physics)
pls help.. if i right click on hinges, motor etc.. and clicking joint setting, no window will open. how can i fix this.. thanks.
open the UI function then select the joint, for sketchy3
Is the VCB supposed to be still usable with the sketchy3 prims? I try entering numbers while creating the various prims but they're not being recognized.
That's nice, it's useful to who wants know about 3d animation like me. I enjoyed this plugin..thanks
This is fantastic work. I look forward to your updates!
In my JOINT SETTINGS for the corkscrew I only have min and max, but on tutorial videos I see on youtube they have accel and damp. Can you help mo how I can add this additional joint settings
How do I know if I got the latest Sketchy Physics version
How do i instal V3 on a mac ? plz respond ! thanks :-D
Absolute gold. Thanks! This kills other 3D animation software. Sketchyphysics is my god!
