Excellent!

[image: OuoI_HiddenGeometry.jpg]Hi mptak, It's the hidden geometry in the track elements that is set to Box. These are the parts that are in contact with the floor.

Not me. SketchyPhysics 3.2 tends to crash on SU2013, so I use it in SU8. Meanwhile, I do wait for an update and the bug fixes.

SU 2013 doesn't appear to have any drastic changes - I hope it hasn't thrown up any hurdles to SP development? http://www.sketchup.com/products/sketchup-pro/new-in-2013

oops rereading your post I don't think I answered you question. I will leave this up and think about the script changes which I presume requires changing instance variables. Yes this is possible via a variety of routes. I think you can just do it by having them all access the same slider value. (just pick one for instance slider('piston2091') and copy that to the others). Otherwise to do it by scripting you just put a variable @@value for instance or ...and this is not recommended $value in the controller field and then change that the value of @@value (or $value) with script. The program can be a bit sketchy sometimes so for original troubleshooting I generally just risk the wrath of ThomThom and go with the global variable $value.

First I drew the two spirals 180 degrees out of phase and superimposed them on a central cylinder. Then I selected the band on the cylinder between the two spirals. Next I selected the other band moved it away from the original cylinder and scaled it down to 90% in both horizontal directions and put it back into the original position. Using one side of each of the spirals, I built a box that fit the two curves. I made the box into a component and set the Shape to ConvexHull. I then copied the component 31 times and lined them up to make a 3D spiral.

Thank you so much! That's exactly what I needed!

@mptak said: Cool beans! I'm glad to see that others are struggling with all this and sticking with Sketchy Physics. I'm by far not an expert but have picked up a thing or two. Your model looks great but I fear that the base cylinder around which your screw is attached may not be being read as a cylinder. It tends to cease a bit on me and I would guess that the large wheel is correctly modeled. Once I get it spinning I'll try to do some of the movie capture I have been playing with and share it back to you. Mr. K provides a great script to enable good capture. I'll look forward to it!!

Thanks MPTAK! I never knew you could define track and follow in a scene description like that. By putting a 'follow' object on a piston, you can have a camera traverse like a 'dolly' shot. I've always tried doing this by starting the simulation, then assigning track and follow by right-clicking, but this is really much better.

@chri said: HI please look a the next picture and try the SKP file may be , it can help you ! bye chri Hi thank you very much. You solved one of my problem with red box. My red box was short.Yellow part some how interact with this red box. Now it fixed. BUt my main problem is with blue part. When yellow part is in down position blue part still move it is aproximately 80 mm . I was expected that this will not move but this blue part continue move . I thought it is fix .

You should just put hinge to limit movement, and motor to move. Put high damp and high speed on motor to make it stand still in position. That is how I make my models, which you can see on my site: http://forsa07.wix.com/dl-design#!design/cc9

Maybe it is best sp setup, but pieces (legs, arms ...) dont colide as they look like. You can see my models similar to this on my site: http://forsa07.wix.com/dl-design#!design/cc9

I have used the left button only until now, is this such a huge problem for you? I have SP 3.2 and scaling the joints with the scaling tool works just fine. Actualy, the models of the joints are made with SU too, so if you enter their group you can also modify them I have not really worked with the gear-tool, so I have no answer here, sry I think they are just some random units with no representation, just as they are used by the integrator. Some real units would be very fine, I think, but unfortunately SP wasn't updated for quite a while Yeah, that happens sometimes, but I lack the insight in the code to say you, what causes it. Better save your model before running the simulation. And don't copy any joints as the integrator can't handle multiple joints with the same adress

Thanks so much guys! Though I had a bit of difficulty installing TIG's truetangents, once installed it solved my problem. The link to the thread was most enlightening. Fredoscale also looks to be another very useful plugin. Thanks again for the help, I really appreciate it.

I believe that the scripts that are embedded in objects in sketchy physics travel with them (they must be attributes) when you copy items but they often go awry because of the naming conventions. I actually have started to put my regular webconsole scripts into an object using sketchy physics as it seems a pretty good way to keep scripts within the file. I just leave a note to copy the script back out of the object and into the webconsole (or what has become the developer console).

Sorry.......I didn't realise the first version had uploaded

The issue solved - the imported model wouldn't move itself, but somehow, placed in a new group, it started moving. Strange things...

@unknownuser said: I did make a small modification to SketchyReplay that records the camera along with the model, and you can then go to Plugins -> SketchyReplay -> Export animation, to export frames as models or images. I'll upload it if that is the sort of thing you are looking for. Hey, thanks Mr.K! I downloaded yellow box, made few scenes and replaced that script, and sketchy animation with controllable camera works! I exported frames as models, because I want to render them. Now I have around 700 .skp files(11 gigs) and don't know how to import them in indigo automatically, only manually one by one. I didn't have problem with static camera sketchy animations where it creates series of .igi files which I can import into indigo all at once and let indigo render for few hours. So my question is how to do it here, how to make 700 indigo scenes out of these .skp files? or any other ideas maybe.. I am not an experienced sketchup user, so sorry if it's a dumb question

Hello Mptak, As Ashscott suggests (thank you!), you should find your happiness with our plugin. You will indeed quickly be able to drive transformations of your choice (rotation, translation, visibility, color, position ...) from data contained in a CSV file. Do not hesitate to ask me your question, for now I suggest you download the trial version and try the quick-start guide (http://www.simfonia.fr/SAT/index.php?page%20=%20&%20PHPSESSID%20=%20r5d5vdo38o0taei07aaqaj9j04%20documentation) P.S: what is a servo? Is this an actuator such as in radio control plane?

As is often the case with geometry errors in SP I exploded every bit of geometry within a certain radius of the problem joint (including geometry it was not attached to) and re-grouped it all. It took some time but the problem is solved... Thanks for the attempt to help Chri Note to anyone else with these kinds of problems - explode EVERYTHING to base level and regroup. Ash
