Changing angle on blades

[APOSTOLISZEV]

Hello,
Any ideas on how i can design blades, on a pipe lets say, so i can change the angle of them easily and fits with the pipe after that change.
Beacuse when i try to rotate them by the command "move" they don't fit to the pipe.
Thank you,

Move is almost never the correct move (pun intended).

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Ok thanks let's say we have this simply case.

I would have made the coils dependent on d1.

Sketch 5 is not fully constrained?

If I run a Compute All (Ctrl b or Cmd B) there is an error...

Sketch6 is a duplicate of Sketch1?

I don't understand why you did the two Moves?

I don't understand what the original problem description was?

Attach a file in this failed state.

Imagine that water flows and i want to find the optimum angle for my blades. To accompish best efficiency.
So i want to change them and see which is a "good" angle. I am going to use theory of triagnle velocity, but i want to see changes in fusion.
By the way thank you a lot for your interest.

Attach file that didn't work as expected.

I want in this geometry, to rotate, to turn the blades.
I want to find a way to do this easily. I dont want to have to fix this from the beggining.

Show me in a picture exactly what is wrong (I think I understand - but if I do understand the issue, you have not shown it yet).

You don't want to fix it???

I was going to recreate it myself from scratch the way I would do it.

If this is too much work for you to start over - I have other work that I need to get done.

[APOSTOLISZEV]

No i mean that i don't want every time that i want to chage my angle to fix a pipe from the beggining.
This is what is happening when i want to change angle

[APOSTOLISZEV]

Those blades had different angle. For the second blade i start over my pipe construction. My point is from the first consruction to change the angle of blades and take notes every time i change them. Not to start over the construction every time i want an different angle.
Thank you

It would have been best if you showed this image of the problem in the original problem description.

Examine the Attached files.

The height of the twist is controlled from the Height parameter variable.

Angle of twist.

Number_of_fins variable...

Parametric table.  Edit Expression as desired.

Let me know if you have any trouble - perhaps I will make a video on my process...

[APOSTOLISZEV]

I see

Thanks a lot

Hello again!!
I want to ask you sth.
Have you any idea on how can we measure the slope of the blades, on the attached file you send me?
Thank you,
