Angle between global coordinate system and local coordinate system

I am working on complex geometry. I am making some experimental modal analysis for that.

So I am suppose to place the sensor on some inclined positions.

Now I want to know what is the angle of inclination of some surface with respect to global axis in all three coordinate system using hypermesh.

Thanks in advance.

HyperMesh

create a node on the surf

duplicate it

translate it along x axis

duplicate it

project it onto the surf

now enter panel f4, select 3 nodes to get angle value

Hi Tinh,

Thanks for your reply.

I need angle in all three coordinate axis.

like how much angle it is inclined in X,Y and Z.

In the above method the angle between three points can be measured (only one angle)

but I need three angle

Hi,

please do it 3 times, you will get 3 angles (just change direction of translation from x to y and z)

If you did steps as I guided above, you would understand

Q.Nguyen: I am trying to use your script. I need more details please. I downloaded it and it is a .tbc file. How can I use it? Thanks

File => Run => Tcl/Tk script

Nguyen: thanks for your reply. I will try it.

Meanwhile, would you look at my post below and let me know if you have any suggestions? Thanks

Hi @Q.Nguyen-Dai, could you kindly upload again your script syst.zip for this solution? Thanks
