rotating parts in Studio animation?

[Anonymous]

How do you redefine/define the axis? using the animation constraints method is not the answer Im looking.

I want a method as efficient/quick as the tweaking method in the .IPN environment.

the lack of help files, tutorials and tech support on IV studio is going to make it extremely difficult to convince my boss to switch the 100 or so licensees of  AutoCad we have to Inventor. ....or perhaps Autodesk cannot answer a problem so simple because they do not know? 
 
 
 
Im starting top feel like Microsofts beta tester for Windows XP when it first came out.

Won't help you with the animation, but we are doing articles on Studio ( long tutorials) in The Creative inventor Magazine.

The May/June issue contains an article on IV Studio lighting. More are being planned. Stay tuned.

Thanks Dennis, that magizine looks very helpful, i glanced at it 2 weeks ago, ill take another look on my lunch break, thankls again.

For "non-constraint-based" animation motion you need to do the following:

1. Use an animation action to suppress any conflicting constraints for the motion you will animate.

2. Use Animate Component to transform the component - be sure you are familiar with the 3D Move/Rotate tool and it's nuances - for moving globally, planar, and rotationally.

3. After animating the component, be mindful of what will happen when the constraints are no longer suppressed.

I know a couple of people who have a tutorial for Inventor Studio that has an index - it's very helpful.  You keep it on your computer so anytime you need to know something just search and watch the corresponding video.  It's kind of like having your own help desk and the quality and content of the videos is excellent.  I can get you the website if you would like.

[Bill_Bogan1]

I pretty sure several of us would like to see that. Can you share it here?

Ive spent about 30 hours trying to use the animate component/3d move tool.  One major problem is it takes the cpu about 3 minutes for each action (4 or 5 total/15 minutes) to use the animate tool and another is that the move triad only button is always grayed out.  My computers horsepower is in my signature.

So for every solution Ive tried (moving UCS, etc) the outcome is always the same.....whenever I try to move the triad the component Ive picked also moves.

Ill need a step by step soilution including what to do eaxactly with the mouse and mouse buttons when the during the 3 minute time the cpu locks up during the excution command.

also can I make all the part movements in the IPN envirmonent and just use  stuidio for the fades, cameras and lighting?

 Thanks in advance.

Nice overpass! Ok... so a couple of things I  can tell you...

IPN (Presentations)

   - designed to help make assembly exploded views.

   - animation was a by product of recording the explode process.

   - a separate file type, it allows multiple explosions of the assembly within the same file

   - it DOES NOT make use of or exchange anything with Inventor Studio

   - If you have Inventor 2011, you have access to IBL and Realistic materials, but not the mental ray rendering engine.

Studio

   - designed to fill the gaps presentations left out, such as constraint animation and realistic rendering

   - uses the mental ray rendering engine to create high end graphic output

   - lives within assembly/part models, removing the data management requirement of IPNs

   - Animating constraints allows for the design intent for movement to be achieved easily.

Alright, with that out of the way...

What are you wanting to move in that assembly? If you are trying to move the entire assembly, then use a wrapper assembly for your top level model. (search in help for explanation of wrapper assembly if you need one.)

If not that, then can you provide more detail on what needs to move in the scene?

So far I have 16 cameras...have of them move......and during those cams i have about 30 movement actions....only one of them was a rotation and it was a pain because i used constraints from points that did not yet exist in the original assembly non studio environment.

but in the small pic I just want those i beam columns to fall down on the ground plane.....rotate around the axis of its lower point 90 degrees

So for future projects can I just start in the IPN environment for all the movements and move to the studio for effects?

In this job I was trying to show the feasible complicated construction sequence of the new bridge being built on top of the old pipe bridge. It has to be done this way because the fluid flow of those pipes cannot be shut down. Only after the new bridge and piping is built can what is known as a “hot top”……….. can the  fluid flow be transferred to the new piping un interrupted. This is at our local oil refinery at Valero.

I will post the 90 sec animation so far on youtube when I get home…its blocked at work.

[Bill_Bogan1]

Sorry, perhaps I wasn't clear, anything you do in IPN/presentations, is NOT transferrable to Studio. The IPN has no association with the assembly, beyond components. IPNs were designed as a separate document to support moving assembly components without affecting the assembly structure/content/positioning and so that it could be edited by non-engineering personnel - such as an illustrator or marketing animator.

So, Presentations and Studio do not PLAY together, at all.

For some of this, if you knew how to use Dynamic Simulation (DS), you could simulate some actions in there and export that to Studio - that IS possible. And, it would allow you to "drop" things. However, if you do not know how to use the DS functions, then I would not suggest you attempt that when you don't have time to learn it first.

I'll have a look at the video when you post it to see if I can think of some alternate possibility.

Just as a thought... does your company happen to have the 3ds Max product?

Sure - I asked my friend when he came in and he said that it is a series of videos, but you only have to order the Inventor Studio one to get the index and videos for Studio.  He said that they are one of the best tutorials he has ever used.  It's called Accelerated Productivity and the website is http://www.trainingtutorial.com/Inventor_Studio2010.htm

The guy who makes them has done up to 2010.  Hopefully he'll have 2011 out soon.

yes we already own one license of 3D studio max... but my main goal was to use IV studio to hook my boss into trying IV out here and once we had IV then to show him the DS and Stress AN capabilities and even Ilogic...all of our engineers are currently using a old stress program.....starts with a C...i forget the name.

As you are aware it is extremely difficult to convince the powers that be to upgrade cad software especially when the boss/owners started out using a pencil and protractor.

like I said Ive figured just about everything out in studio except redefining the axis in rotations. Ive been using IV since 2002..... 5.0 when I took the 40 hours course and have about 8000 hours since.

[Bill_Bogan1]

Sounds like you're trying to help them see the value of digital prototyping. I applaude you for trying to show the value to them.

Once I see the video, I'll let you know if I can assist in any way.

im building the video in reverse so my next step is at the begining to make the 2 columns fall on the ground.

[Bill_Bogan1]

Vincent, that is excellent!

Building it in reverse... interesting. So, the ultimate goal is to "deconstruct" the frame around the piping?

Given that you already know what you're doing, please take the following as simple brainstorming from my perspective - which is, I have no idea what constraint relationships you have assigned.

If I understand, you want to tilt the beams up/down, just as you have done for the other pair on the right. Did you use an angle constraint for the beams on the right? The left would be similar.

E.g. constrain an EDGE of the beam to the ground component, this would allow you to keep it in contact with the ground but it could pivot at an angle to the ground as well. Then, the angle constraint to tilt the beam.

To slide things around, you could use a constraint between the appropriate origin plane of the assembly and that of the component that is moving.

Those are just a couple of thoughts in passing.

You done a beautiful job so far.

this is a .IPN video I made in 2002 with IV 5.3.  I made the model in a month and the animation in only a day....it was 10 times easier.

http://www.youtube.com/watch?v=yV6xeDba6qM

Yes i used constraints to move the other 2 columns which was too much work. I want to use simple tweaking rotations as in the IPN.

"E.g. Constrain an EDGE of the beam to the ground component, this would allow you to keep it in contact with the ground but it could pivot at an angle to the ground as well. Then, the angle constraint to tilt the beam."

this will not work.........as the the path does not always stay flush with the ground.And even If I adjust the flush constraining there is on more constraint I will have to make locking the distance back to the structure to that bottom so the column base doyens kick out.

Forget the constraint idea..Just imagine that I am trying to move a entity in a zigzag-  path.....Then rotate...Then another zig-zag and another rotate.

I need to know how to move the triad

[Anonymous]

I forgot to mention...im building the animation in reverse because the "destructed" scenes final locations of each part as a lot more lee-way than the "constructed" scene where all the parts mate up perfectly.....animating the components whith the drag of the mouse.

and fyi i reversed the animation back to the original order in sony vegas video...not the reverse button in the animation rendering box...i dont trust it.

[Bill_Bogan1]

I think the workaround to your problem is a positional representation. If you want to do complex motion, you will need to define more positions than just start and end, specific interim ones where the positioning changes are what you want.

See attached wmv. The wood block has no constraints on it, I just dropped it in.

1. Create a new positional representation.
2. Select the component that will change positions, right-click and select Override...
3. On the Component tab, check the box next to Grounding, set the value to ungrounded if not already so.
4. Check the box next to Position Offset
5. Move your component into position. Click OK.
6. Test the posrep by dbl-clicking the master, then the move posrep.
7. If you plan multiple reorientation moves, use several posreps as keyframes for the moves.
8. Go into Studio.
9. In the animation timeline, set the time slider to the time you want the movement to be completed.
10. Click the Animate PosRep command.
11. Select the From and To posreps, specify the timing for the action.
12. Repeat as needed using the various posreps you created.

When doing any animation in Studio, people often overlook the fact that you can make animatable action an instantaneous action. This technique allows you to position things in frame 0 so they are where they need to be before you ever start recording the animation.
