Hinge 6 moving parts 7 rotation points

[willem.creffierKCWFB]

I have the drawing of a hinge, in which I clustered the six moving parts as different blocks.

There are 7 rotation points.

The red piece on the right is fix, all the rest moves.

Is there some kind of tutorial or example  I can follow, in order to modify the Dynamic block, and have this work properly?

I guess I start at the other red element, and work my way up to the fixed red element? 

Kind regards,

Willem

I don't know of any tutorial.  

You only show 6 parts total and one of them is fixed, so only 5 can be moving.  There are some hidden lines that don't seem to have any relation to parts that are behind. 

I doubt that is possible using dynamic parameters/actions or at least not possible for single grip movement.  You could obviously add multiple rotations at the various points and then need to manually align the various points.  Single grip movement might be possible using constraints.  @j.palmeL29YX would likely be the best source for advice in that case.   

Post your block for better advice.

You are right, 5 moving elements.

I removed a spring to make the drawing more readable.

Single grip movement sounds promising.

I have no clue what the exact functionality is we need within Dynamic blocs, but I would be disappointed if we had to purchase Inventor in order to make this work.

You don't need Inventor. Post your dwg file (don't remove the spring) please.

Without knowing the correct dimensions, attached you find a principle solution how the mechanism may work. Drag the rotation grip on the top of the model.

Hi Jürgen, 
nice to hear from you.

Please find the drawing attached.

The spring is the yellow line.

the result should be something like this

It would be nice to have the link to some kind of tutorial on the subject...

Kind regards,

Willem

Please follow the steps shown in the video. 

(Sorry for the small typos in the video). 

Modifying the sub blocks is not shown in the video, you can examine each of them one by one.. The main changes: I deleted not needed dashed lines and converted dashed contour lines to continuous linetype. Additional I filled each of the contours with an invisible hatch (color 255,255,255) to hide the objects behind. I think these modifications are for you easy to understand and to do.

Hi @j.palmeL29YX ,

nice that you take the time to make this very instructive video.


Everything goes well, except for the penultimate step...the selection of the last block.

For some reason, the point on which to select does not pop up.

So I have a functional hinge, except for the orientation of the last part.

Is this Karma, or is there a rational explanation?

I try to explode and recreate the block, but this doesn't help.

When  I make a new block...even just  line....I get it up & turning.

Nice to see that the maximum rotation equals the specs of the manufacturer.

I can continue my design, but I would appreciate if you could check why the last block is not "selectable"

MFG,

Willem

You set the subblock "Wand Arrm b" to "annotative", but that must not be. 

I'd suggest to redefine this block:

All right, thank you so much!

For information only (I "played" a little with this model): 

Since I don't know what you actually want to achieve, I'm still not sure whether my suggestion above really was/is helpful in solving your problem. Is it just about depicting the mechanism in different positions or moving it dynamically? Then my suggestion above should be sufficient. Or do you absolutely need the hidden lines to be displayed during movement? That should also be possible in AutoCAD (with some limitations).
But if you want more, you will need a more powerful program. For testing purposes I modeled the mechanism in Inventor. Here you can analyze and research the mechanism in detail. For example, it is easy to see that the spring in Pos_1 (the second to last image) has the shortest length. If you move the mechanism towards the end positions Pos_0 (the image before) or Pos_2 (the image after), the spring relaxes. In other words, the mechanism is depending on the current position moved up or down by the spring force (inclusive the gravity). Or you can determine what forces are necessary to move the mechanism depending on the mass attached to Part2 (the rosa/pink one), and much more. But all of this cannot be discussed within this thread. 

An Inventor example for demonstration:
