SketchyPhysics 3.2 Need bug reports!

qpwoeipt

Hi there

I think I have one... I noticed that size of a given object it doesnt work.... if I scale it up past a certain size it works.... (ujoints) any answers to that thanks

I'm using MM and the object size (doesnt work) is 16mm radius!! will post and exact point when it starts to work..

Hi C. Philips, I also found a problem with size.

I was building a mechanism and found that some parts didn't move but others move.
Isolating the problem I found that small objects were rock solid.

To further debug I started a new design with only solid floor and a vertical bar measuring: 7.5mm x 1mm x 65mm
You do the sim you will see it doesn't move anywhere.

But as far as I see it's a great work so far, but needs really some huge work to improve usability regarding the collision hull's, it's a lot of work to convert concave objects to sub-groups of convex objects. Maybe some automation could be done here.

Other thing I believe is that as less tools added to SU, as better. So the plug in should adapt seamless to SU and add only tools for joints and sim. Also copy paste, is other thing to improve - solving sketchyphisics problems - not creating other tool to copy

Other suggestion: a joint path tool : object moves along a defined polyline on space: just like follow me tool of sketchup but for movement of objects.

What about just having one joint for any work ? After all a joint defines 3 degrees of liberty of linear movement on X,Y,Z axes and three degrees of angular motion in each axe. So you could have a joint and you simply lock the degrees of liberty you didn't wanted for some joint.

Well it's better I don't say anything more you should have your hands full of work.

Thanks for this great plug in.

I think it is the dl.bundle

Version 8 with SP3.2

Can't connect joints. Ctrl does not bring up (+) on cursor.

Following the directions on the bottom bar the same problem existed until the Option [⌥] Key was used instead of Ctrl.

I ‘think’ that the version of SketchyPhysics that is in use is 3.2.
That is I downloaded from a link that implied it was SketchyPhysics 3.2.
In SketchUp under Help>About SketchyPhysics it is quoted as SketchyPhysics3.

In the same vein under this forums FAQ on SketchyPhysics there is a post indicating that the latest version download will be contained in a ‘sticky’ at the top.
Of course I may be the only one unable to see this ‘sticky’, but being able to immediately locate the latest version of this most valuable PlugIn would be very much appreciated.

With regard to actual ‘Bugs’ I find that e.g. Wheels set to Shape = Convexhull sink into the StaticMesh Floor if they are attached to another Object, or fall through if they are not connected to anything else.
Changing the Wheel to Shape = Sphere resolves the problem.

With regard to stability my experiences are similar to other posts above, very frequent crashes improved by not attempting to use the Mac Ctrl Key when using the JointConnection Tool to attach a Joint to a Mother Object.
I always try to recall the events leading up to ‘crashes’, but for less knowledgeable folk such as me it would be useful to learn what is most useful to you in these instances.

Power to your fingertips, your efforts a truly appreciated.
Very best wishes.

Hello,

I'm new to Sketchup, SketchyPhysics (1 week now) and SketchUcation .. I'm a fan of All and I'm an Autocad user from R12.

I've Installed SP3.2 from (SetupSketchyPhysics3.2-Dec2.exe).

It seems to work ? ...I have a 'blue axis' learning curve.

However,

I have a constant note: "Requires SketchyPhysics3.2" in the upper-left-hand corner.

I cannot seem to access 'joint settings' from rt. clk on a hinge (for example).

I don't know of those are bugs ?

Thanks for the very coool 'SketchyPhysics'

I also have downloaded sketchyphysics 3.2-Dec.exe for Mac, and keep getting the same error message (requires SketchyPhysics 3.2) Mac OS 10.6 Sketchup 8

I have just updated to MAC OS X Lion 10.7, Sketchup 7 (7.0.8656), Sketchyphysics 3.2
All my Sketchyphysics tools are empty, I can open them but nothing in and I get this error loading message when I open Sketchup:

Having fun playing with SP - my first go at real physics modelling.

However, I'm having lots of random crashing when the simulation is running.
Sometimes I can run many times over without any crashes at all, other times, almost immediately after pressing the play button.

-Seems to affect all of my models, not any one particular file or geometry type.
-My 'noob' models are all pretty simple, mostly using just the default geometry from the SP toolbar.
-Always crashes to 'Runtime ended in an unusual way' or just straight to the desktop, never a 'bugsplat'.
-Tried all the forum recommendations I could find - no shadows, no edges, SP UI screen closed, disabling OpenGL acceleration, etc.
-Apart from the crashes, the models behave just as I would expect.
-SU8 is generally very stable on my machine when not running SP.
-WinXP SP3, Q6700 CPU, 2GB RAM, GeForce 8400 GS, SU8, SP3.2.

I did see in earlier posts a request for error report generation. I think that this would be a very good idea, even if it is just a 'crash dump' text log that could be e-mailed manually.

Models slipping and sliding on "floor".
I just made a simple 4wheel drive model with a servo for steering, steering works. model moves,model doesn't respond to steering, "floor" is just too slick (or at least that is the way I am describing it)
Also there is a "hopping model" issue.
any solutions?
I also just noticed this thread was started nearly a year ago, several reports, nothing from the creator of this plugin within the past few months. Is there anyone reading this?

Camera track and follow, do not work when recording animation frames.
A screen recorder doesn't work well at all, the video is stuttery, and looks like junk.

If one downloads a Sketchyphysics Model from 3D warehouse directly into Sketchup it needs to be Exploded first in before running it else there will be a Bug Splat!

Never had that issue, but you need to make sure that you are running the same version of SP as the downloaded model, this has been my experience anyway.
Bug Splats are a way of life when using SP, you just keep going, and if you have more than two or three splats on one model, then you may need to figure out why.

yonic

Uh... well... I used SP for 2 years... but now that I donwloaded the new version of SP, I founded a bug...

On SketchUp 8 Pro, when I use the Joint Connector, in SketchyPhysics 3.2, the cursor turns white somehow, when it should be black. When I hold the CTRL key the plus (+) mark does not appear near the cursor...
And so, connecting joints don't work anymore.

I tried to follow the message of NotSoNaff, but nothing works.

Is there a fix for SketchyPhysics 3.2 so it will run on a computer that says you need 3.2. Every time I load 3.2 it shows that I still have 3.1. I finally have created a car with motors attached to each wheel. This model will move in a straight line and I can successfully change speeds of the motors. However whenever I ad another function i.e. a hinge on the front wheels to have the car turn, the model falls apart. It appears that adding any new functions to the successful moving model just negates the first setup. Where can I find good tutorials for the use of this program. I've seen amazing videos of models doing great things with SketchyPhysics i.e. a jeep traveling across ruff terrain. I would like to master these things. Please help.

Hi Don, OK when you add another ie a hinge so a car turns, first thing is don't use a hinge use a servo. What I did at first, was hit all the tutorials I could find, and get other people's models from the warehouse, take them apart see what makes them "tick".
I have done OK, using this procedure. there is one tutorial in particular, that helped me out immensely. look at this.
http://www.youtube.com/watch?v=71NlDJlA9S0
watch this perhaps even save it and watch it again, when needed.
This video will get you started.
Let me know if I can help you out.

Don East

tspco, I have been working with the YouTube video you listed. An it's the one I'm having the problems following. It works fine until I put on the servo and then the model falls apart. It's like the servo planed over the other hinge or motor just negates all the previous setup. Any thoughts?
Don

tspco

in this case the hinges are grouped to the boxes, servos are connected to boxes, then the rear motors and the servos are grouped to the body, then it "should work". please note the difference between grouped and connected.PM me for more
just a thought, grouping the motors and servos to the body should be the last thing you do before running the simulation. If it works great if not post your model to me in a pm and I will try to troubleshoot it. just the skp please. SP is a tough one to learn what is connected to what and what is connected to what. Again pleaase PM me for more that way this thread stays as it was OK

Hey Chris are you still out there? Never found an answer about the error message in this thread!?

Chris..

there appear to be at least 117 issues logged,... none have been acknowledged that I can see.
