Dear Michael, I would like to know whether it is possible in principle (in the future) to rig elements in MOI3D?

In Sketchup has long is available plug "SketchyPhysics", allows you to combine objects in a hierarchical and manipulate arrays.
Of course, I do not suggest doing a full animation, as it allows SketchyPhysics.

But sometimes you need something like this: http://www.youtube.com/watch?v=9vU2MMc-woM
or this: http://www.giantmonster.tv/giant/?p=364

I would be grateful for your answer, thank you!

Hi krass, the overall concept behind MoI is that it's specifically targeted on modeling and not animation, so it's pretty unlikely for something like that to become a direct part of MoI in the foreseeable future.

At some point I would like to make it possible to do some more extended plug-ins though and maybe at that time someone else could do a plug-in like that.

But I'm sorry in general I'd say that's pretty far outside of MoI's main focus.

Dear Michael, of course I didn't mean no animation no animation!
I only mentioned a more convenient approach exactly (!) in the modeling.
Often, when it is necessary to operate directly with a group of interrelated parts and without the "bone" of the binding elements to each other is very difficult and long to do the job.

Example.
I have a lever attached to the other lever. So on.
And, if I need to rotate the first lever relative to their initial positions, then - of course - changing the whole relationship between the leverage in the model and you have to count all over again.
No animation! Exclusively Modeler.

So the question: does in MAID the opportunity to do something similar with the help of stannic script (or something else)? Or is it impossible in principle?

Hi krass, do you mean an "inverse kinematics" type system where types of joint movements are defined and lengths constrained and stuff like that so movement of one component brings others along with it?

If so unfortuantely there is a lot of complexity involved in the setup and UI management of such things - in an animation program where that function will be highly used it makes sense to dedicate a lot of programming time and UI real estate to that problem... For a modeling program where although it could be useful, it's just not something that is a really a core function of the modeling environment and it gets difficult to justify the resources that would be required to dedicate to it.

Maybe in the future at some point but I think it would likely be a ways off.

Possibly you might get some current use out of Transform > Rotate > Rotate Axis, which allows you to rotate objects around any arbitrary line in space. You could try something like include the axis lines in your objects and then use them to snap on to when rotating different selection sets.

- Michael

Thank you, Michael! I will try to Transform> Rotate> Rotate axis. Maybe it will help in solving my problem.
In fact, the modeling of the various methods of rigging the general assemblies and parts but not so rare vesh.

In any case, thank you for your answer, and you're so watch carefully for soobschestvomi improve your wonderful product!

Michael tried your solution - alas, it is a little what I thought.
To illustrate his thoughts would show a picture.

Maybe the free DesignSpark Mechanical (who has drawing with constraints) can help you ?

Dear Frenchy Saw, I understand that you recommend to leave alone MOI3D and switch to another product? What's the point?

Just pick functions that not yet existing (dimensions) or weak in rare situations (fillets) !)
As gobetween is very easy : Step - Sat as shown in my previous link! :)

Dear Frenchy... I'm afraid we're talking about very different things.
Or I do not understand what you want to tell me your answer, I'm sorry ....

Just that from your image/Rig that you shown, (who don't work in Moi) i believe you can make it with the prog quoted above! :)

Incredible! )))
1. You are asking me to model in MOI3D,
2. When do I need to turn a group of related objects in some corner, you offer me to go into some other program (I do not know) and continue there
3. Question: what is the point of MOI3D? After the program, as recommended by your model can be successfully done from the beginning?

How do you imagine the very sequence ??

And if we talk about third-party programs, that is, that's an interesting - Onshare.

It perfectly realized modeling techniques, of which I spoke.
But it oznachat you need to get away from MOI3D and learn other software and it design your work. The point?

PS. By the way, just such wonderful callouts with dimensions as shown in the video above, it is not enough to MOI3D. Alas.

I had understood that you want modeling something with constraints for make some rigging adaptations
and that Moi don't realise that! :)

<<Onshare ?

Onshape yet commented here! ;)

Not really.
I would like to understand whether it is possible in principle (hypothetically) in MOI3D through plug (as in sketchup, for example), the implementation of this feature.
Or the engine program that does not natively support, and does not allow for.
That was the question)))

I suppose quasi all is possible but must ask some many times to make! :)
(and of course a very solid knowledge of developpment! )

See the plugins of Max Smirnov for example! :)

Hi krass,

I guess anything is theoretically possible - maybe with several years of full time work someone could build some enormously complex scripting layer that would do that.

But to be practical a constraint mechanism like that would really need to be more built in to the core of MoI.

It is something that I want to add in the future but there is a lot of work involved and so I don't know when it will happen. MoI is currently much more focused just on trying to make the initial drawing of things to be as fast and fluid as possible and the focus is not on that kind of post processing editing that you are describing.

There are other programs out there that are more focused on doing that kind of editing, so if that's an important function for you using a different program that has prioritized that type of workflow would be a good idea. The tradeoff will be that programs that are heavily focused on parametrics and constraints will require you to do more planning and setup work for your drawing and you won't have the same feeling of free drawing as you do in MoI.

Another program that you might want to check out which is very focused on constraint editing is SolveSpace: http://solvespace.com/index.pl

- Michael

Michael, thank you very much for the detailed answer!
I like MOI3D so that I will somehow get along without these functions for them to move to another platform simulation! ))))

Yes Solvespace is cool (I have made its French Site :)
http://solvespacefr.weebly.com/

But free DesignSparks is more ergonomic :)
What do you want more simple for constraint something ?
As soon as you can see a "Star" you can edit if you are in compatible constraint!



In 3D the same!
