    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!

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

                    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."

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

                            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!

                                  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.

                                      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.

                                      Anton

                                        Hi Anton

                                        Many thanks for your reply. The solution makes sense. It will make modelling gears a little more complicated but that is ok. I guess I could also let the gears run as cylinders on a box collision shape for the rack (so they roll effectively) and null the gear teeth on both.

                                        I don't know if it helps you to know that when Collision Wireframe is enabled on the simulation it shows fine but if you use orbit the wireframes are lost. It means you effectively have to stop the simulation, orbit to where you want to see and restart in order to get the view you want with wireframe.

                                        It is a minor problem for me but maybe it is a bug that you are not aware of and can fix.

                                        Thanks again for your help.
