how to bind a screw in a curved compas

[vincixanni]

Hi, I'm new to the forum and I've probably published in the wrong trend, so sorry. I have a problem to bind a m24 screw in a 30-width curved bay and describing an 11-degree angle. the goal would be to make the movement of the free screw within the limits of the asola but, I managed only with the transitory bond to make it move tangent to the surface of the asola. Trying the internal tangent bond instead I can't set the limits well to make it move from one joke to another.
I hope I was clear and thank you in advance.

I would do like this:
- creation of the two axes of the asola;
- flat creation with the above axles;
- constraint axis of the vine with the plan of the previous point;
- maximum axis distance bond from the two axes of the first point.

the screw remains untied in its axial movement that must be set according to the needs.

oyster... I didn't notice that the asola was curved.
my advice was for a straight asola.. .

try to create a halfway plan between the two inner faces of the axle and ties the axis of the screw with the newly created plan. If necessary to set the limit of the screw I would give a +/- bond between the axis of the screw and the axis of the initial circumference of the asola.
In this way the screw can move only within the specified limits but coincide with the plan.
I hope I've been clear.

misses little to the holidays! ! ! ! !

I would do like this:
create in the screw a distant axis as the central radius of the asola (and also in the asola create the same axis, from the center of the axle)
the two axes by setting the limits with maximum equal to half of the game and minimum 0
ties the angle movement with plans.

If the screw is in the center, I see it hard.
If you look at my footage, that is the right method, I have been using it for years and I have never found anything better, few constraints and safe behavior.

I agree with the stefanobruno system.

Thinking about it, it is a pity that in addition to axles and planes you can not create other surfaces to use as constraints. in analogy to the equidistant planes, it would be interesting to be able to build a cylindrical surface as equidistant from other two and then use it as a bond.

Nice, man. very close to what hypothesized.

From the formal point of view, this seems to me the best solution, even if I would have built the reference surface to the center of the axle and I would have bound the axis of the screw and not its outer surface.

In this way, even in case of change of the width of the socket, the screw would have maintained its position.

But it doesn't seem to work with the axis...

 

[exxon]

That's what I'm feeling.

 

[stefanobruno]

Yes, it is true, only that the transient bond has unpredictable behavior.
works 3 (or x ) times and then jumps out of the path, no apparent reason.

1) with the "transitional" bond you can only work with the tangency, so you can not bind the axis (spected... ).

2) I confirm certain "foreign" behaviors: I have had errors of incompatibility between the constraints that then have resolved only inverting their assignment (bad thing...).
