Hi, i try and try to move a part on my path, i look many youtube tutorial and i look at SWX tutorial, all seems simply and easy but when i try to do the same exercise with my swx professional a fail all times ....
Here you find my last experiment, an here you can look how it fails ....
http://www.youtube.com/watch?v=JMoFJffarYA&feature=player_embedded
Could you help me to find the right way?
Hi Scott,
Tnx for your attention and reply, the only fixed part is the path (i think this is correct)
all the other parts are free to move long the path (as you can see it in Youtube video
or in the attached assembly).
As I write i "think" i do all right, but the simulation run badly...
Could you help me finding what's wrong?
PS: i've swx2011 professional (non premium) but i think simulations it possible
also with professional... or not?
Hi Luca,
Yes the simulation is offered in the professional as well as the premium.
http://www.solidworks.com/sw/products/simulation-software-design-analysis.htm
I have used the simulation, but last version I used it on was 2009.
I looked at your youtube video and while I could not read the spanish, it looked
as though the assembly moved quite well around the track. So what am I missing?
I do remember that depending on how you had the time intervals set would determine
whether the video cam out jerky or smooth.
Ok, so with my version IT'S POSSIBLE TO DO!!!
...but in my YT video you see thet my assembly come out jerky AND smooth....
... also changing speed and or time it come again out jerky AND smooth... and some times it come ahead and go forwards...
...and i dont understand what's i wrong...
Pleeese help me with example or tutorial or something else...
PS I'm write Italian not Spanish (if you dont understand, dont mind it's just profanity and outbursts ;-P)
Hi Mark,
tnx for your reporting,
Yes, it seems that Alessandro and I are working to the same thing.... but we are not colleagues or neighbors ....
I believe that Alessandro wanted to help me with this problem, and I believe that Alessandro took the zip file from the Italian forum... no problem, indeed, I thank him!
I usually try to resolve the problem by asking first to the Italian forum (written and understand in Italian it is easier for me), but if I can not fix, I try to write here in the international forum ...
At this point I see that Alessandro wrote in
"SolidWorks Forums> SolidWorksSimulation> Motion Studies> Discussion"
and I wrote here in
"SolidWorks Forums>SolidWorks> Assemblies"
I think it is better to continue the discussion in "SolidWorksForums> COSMOS> Motion Studies> Discussion ",
so I ask you all to follow thediscussion in that place: D (https://forum.solidworks.com/message/217554#217554)
PS: Before I answer in one place, I want to test the examples that you have attached.
Thanks and see you soon!
Sorry about not recognizing the italian. And seeing it was profanity, I am ok with not being able
to read it. Don't need to see that stuff!!!
Here is a instuctional link to simulation. Also go back to youtube and look there which I think you \
already did. Did you check out the tutorials inside of Solidworks on simulation as well?

Hi Scott and tnx to be here again
I see you link to me instruction to do a simulation and now I understand that I have NOT explained well what I want to get: I dont want to test the material (Stress Analysis), but i just want to "simulate" a motor applied to my part in order to have a file.avi showing the movement (without my hands/mouse)... ok?
(I'm sorry my bad English)
In my YT video you can see the 1# part when I move around by hand and the 2# part you can see i've lot of problem to do the same with the motion study...
"Also go back to youtube and look there which I think you \already did." ??? I'm sorry but i dont understand what's you mean..
PS: As I write here above, I invite you to follow this discussion in the other discussion.
Tnx and see you soon
No problem Luca. Just trying to help you figure this out.
Are you talking about Cosmos simulation like for stress analysis?
No, not Cosmos simulation for stress analysis but just "Motion Study"
please continue this discussion in that place -> (https://forum.solidworks.com/message/217898#217898)
Good Luck Luca with this.
I believe you can do this and it will work out fine. (I just did a very similar animation last August that worked fine, too.)
First, you shouldn't create animation points that move more than 90° around a bend at one time. It's best to break it into smaller pieces (such as 45° or 60° increments) per move in the animation. This helps prevent SolidWorks from getting confused and causing the jerks.
Next, be sure to "rebuild" the animation after adding each point of motion. This will also help SolidWorks from getting confused.
Next, I don't think you need two paths. This can cause trouble. If you can use a single path, this will be best. Constrain the rest of the assembly from moving unpredictably by adding mates, such as the "front" plane of the moving assembly is parallel to the "front" plane of the top-level assembly. Then, when the moving assembly follows the path, it will move predictably. If you need both of the twisting parts in the moving assembly to work in unison, simply apply a plane mate between the parts (such as parallel or coincident) and that will still function with a single path.
For the path, it will probably work best if the path is a single surface--as opposed to tangent surfaces--so you can convert the sketch that makes your path surface into a single-entity spline with the Convert To Spline feature in the sketch.
I think that's all you'll need to get this to function. Good luck.
--Forgot to mention this--to calculate equal distances around your path, do the math and add a sketch to indicate your starting and ending points per move in the animation. (Remember, you don't want to rotate your movement more than 90° per step in the animation.) So the sketch can indicate the starting and stopping points per move if you're doing this manually (which will be more smooth than a motor for this oblong shape). The result will be a very smooth animation all the way around the path.
Hi Jeff, Hi Scott, I think i'm on the right way, so if you want, please follow me in this discussion -> (https://forum.solidworks.com/message/218479#218479)
Thank you very much!!
Luca,
First make sure your model is not fixed in the assembly. You can tell be if you
look in the feature manager you will see an (f) next to the component. If it is
RC on it then select "float". If this is the case now try it and see what happens.
