Just installed Sketchup Make 2017 and tried to install MSPhysics 0.9.6 and AMS 3.4.0 and got this error ---

That's unfortunate. Looks like I will need to create another account to ensure that the encoding error is actually not fixed.

Hi,

I'm want to do a path following object, but I don't really know how. I found on this thread that it's done with curvy joints, but I'm lost. Please, can you explain how or do you have kind of example?

Thanks!

Anton_S

Okay, those loading and encoding issues should be fixed now. Upgrade to 0.9.7.

Hi M3one,

At the moment, you can refer to this tutorial on curvy joints.

You can also check out this example model at 3Dwarehouse.

Thanks Anton, I'll check it later

Thanks Anton that has sorted the loading issue with Sketchup 2017.

Hello, I can't download MSPhysics 0.9.7 plugin from your link!

First of all thanks for sharing this great plugin
Please I need help. with chains.

I installed the last version 0.9.7 and it appears this message:

Hello !!!
I think most stable version is MSPhysics_0.9.4 for now ... in MSPhysics_0.9.7 "Drag to orbit" does not work when the simulation is runing...
Emersonvip - you can browse through this forum about chains ( http://sketchucation.com/forums/search.php?keywords=chain%26amp;t=56852%26amp;sf=msgonly ). Here you have a file, see how it was done this chain piece by piece and you will understand how MSPhysics it works with chains.
as Anton wrote in a reply "You can adjust Update Timestep, Solver Model, and Update Rate for the desired speed, performance, and stability."

Hi Anton and thanks for MSPhysics your done a great job so far congratulations.
only problem for me is new MS scripts are confusing....old sketcky user
waiting on more models with script examples in them.

Scaled down my j-pod/cable car model from Eneroth Railroad plugin

Curvy piston joint testing

thx again

The same here - Orbit doesn't work during simulation. Zooming in and out works.

Yes, For me also don't works the Middle click in 0.9.5+

Anton_S

Hi,

Oxer, I fixed the loading issue on Mac OS X.
Cristyan, Faust07, PituPhysics the orbiting issue should be fixed new.

Please upgrade to 0.9.8.

Thanks y'all for reporting!

Anton

Oxer

Thanks!!
All works fine right now on Mac.

Hi Anton

Please, please could you help me.

Firstly thanks for making it possible for us all to have this plugin. I really appreciate your work.

I have one little problem which I am sure is easily remedied. In my models the groups or components are falling through each (like in the following post) a lot of the time.

http://sketchucation.com/forums/viewtopic.php?f=61%26amp;t=64189

I need to change a setting somewhere I guess but I have no idea which. I hope I haven't missed something obvious, I have tried looking for the solution online without success and I have tried systematically changing setting also without success.

Many thanks once again.

Hi Anton

Is there a way I can tidy up the collision wireframe for Compound from CD shapes in the UI. Both the rack and the pinion I have drawn are not getting a very good collision detection wireframe so the gears are jumping out of the rack.

I have checked the geometry in the models and they appear to be sound so I am assuming this is related to the way the wireframe is generated/calculated.

Thanks again for this great plug in.

Anton_S

Hi, DonDeEs,

The Collision from CD shape is not reliable. Its ability to calculate proper collision is limited. What you can do is manually divide sub-geometry of the gear into convex-hull groups. Then assign Compound shape to the top level group. So, for the gear, every tooth should have its own group. The top level group, of Compound shape, should contain all the teeth.

For the chains, using collision as the constraint for keeping the objects from falling apart is not a viable approach. Yes, increasing the density of all chain links can get all pieces to hold tight, but they will break once a certain amout of force is applied. What would be a better solution is having every peace of chain interconnected by a ball-and-socket joint. There is a very efficient way to do it. Here, check out this example:
artificial_chains.skp
I might create a YouTube tutorial for it later.
