Nx Journaling - Orient WCS as per User selected Cylindrical Edge.

Kumaresh_07 · May 14, 2020

Hi all,

I would like to create one journal to Orient my WCS as per selected cylindrical edge.
I have spent so much of time with this. But still I couldn't figure out.
My requirement is while running the journal, it will ask me to select a Cylindrical Edge, Once I select the cylindrical Edge, WCS will oriented as per that edge (Note : Selection scope should be Entire Assembly).

If you have any further clarification means, please check attached Nx Recorded video.

It would be great, if someone help with this.

niedzviedz · May 14, 2020

Did You try to record journal, it's much easier (sometimes) to edit recorded file, than create it from scratch? Sometimes nothing is recorded, so the nxopen doesn't support some features for example boss.

With best regards
Michael

What do you mean
“Orient my WCS as per selected cylindrical edge” ??

Where do you want the origin, the x-axis, and the y-axis to go?

Kumaresh_07 · May 15, 2020

Hi Bubbak,

We can orient wcs as per Csys of Of object.(Note : X,Y Origin Not needed).
Please refer below attached video link ,you can easily understand.

Hi Michael,

yes , i have also tried to create my required journal from recorded journal.
But I don't know how to code for user going to select cylindrical edge.
please check below recorded journal & attached video link for better understanding.

I want to modify above journal as like below steps.
while run the journal,
1)User prompt to select a cylindrical edge.
2)once cylindrical edge selected,,, then wcs going to automatically oriented as per selected cylindrical edge.(Using Orient WCS option).

please check attached video.

Hi Michael,

First of all ,I m a beginner in Nx journaling,From you people i learned lot of stuffs.
You almost done.Thank you very much for your efforts.

Yes , In Your modified journal the one and only issue is wcs orientation.
I m trying to figure out almost 6 hours for this.Still i couldn't. But i have some hints ,it may be helpful to you.

Code:

workPart.WCS.SetOriginAndMatrix(origin2, matrix1)

The above code snippet shows main functional part of our journal. The main two stuffs are origin2 & matrix1.
You already fixed the first stuff origin2 as per selected cylindrical edge.
But the second one is : matrix1.
As of my knowledge, For fixing orientation we need 3x3 Matrix. So we can declared above matrix1 as matrix 3x3.
But here my issue is , I don't know how to extract matrix 3X3 values from selected circular edge.
So for, temporary solution : By using below code snippet, I have extracted matrix values from current wcs orientation.

Code:

Dim matrix1 As NXOpen.Matrix3x3 = workPart.WCS.CoordinateSystem.Orientation.Element

But this temporary solution is not good so far.
Please let me know , if u have any idea about extract matrix 3X3 values from selected circular edge.

Thanks for everything Boss!

In niedzviedz's code, an arc (edgeCurve) is created from the selected edge. You can get all you need (origin and orientation) from this object.

[spoiler big hint]take a look at the .Matrix property. The .GetOrientation method would also be useful here, but might take more work to get what you want.[/spoiler]

Kumaresh_07 · May 17, 2020

Thanks for your information Cowski. I will take a look on these topics.

niedzviedz · Jun 1, 2020

I dig in documentation and Arc.GetOrientation provide origin and 2 vectors3D x and y. What about third one z? Matrix3x3 need 9 values: Xx, Xy, Xz, Yx, Yy, Yz, Zx, Zy and Zz. How to convert Vectors3D to Matrix?
I tried this, but it doesn't work properly (Csys vectors are in different directions):

Code:

Dim Vec1 As NXOpen.Vector3d = New NXOpen.Vector3d
Dim Vec2 as NXOpen.Vector3d	= New NXOpen.Vector3d
edgeCurve.GetOrientation(origin3, Vec1, Vec1)
Dim x As Double
Dim y As Double
Dim z As Double
x = Vec1.x - Vec2.x
y = Vec1.y - Vec2.y
z = Vec1.z - Vec2.z
Dim Vec3 as NXOpen.Vector3d	= New NXOpen.Vector3d(x, y, z) 

Dim matrix1 As NXOpen.Matrix3x3 = Nothing
matrix1.Xx = Vec3.x
matrix1.Xy = Vec3.y
matrix1.Xz = Vec3.z
matrix1.Yx = Vec1.x
matrix1.Yy = Vec1.y
matrix1.Yz = Vec1.z
matrix1.Zx = Vec2.x
matrix1.Zy = Vec2.y
matrix1.Zz = Vec2.z

With best regards

The .Matrix property of the arc object is the easy way out. But if you really want to use the .GetOrientation method, you can use the vector cross product <Xvec> x <Yvec> to get the Z vector and use those values in your matrix. There are functions in the API for the vector cross product (or you can create your own, it isn't difficult math). However, I'd suggest using the UF_MTX3_initialize method. This method will take the X and Y vectors (3 element arrays of values representing the vectors) and return an array representing the orientation matrix. These values can then be fed into your orientation matrix object.

Do select face instead of edge with
the z axis normal to that face
help you.

niedzviedz · Jun 3, 2020

.Matrix property of the arc gives Matrix 2x2, so I have to convert it to Matrix3x3 to use it in "workPart.WCS.SetOriginAndMatrix(origin2, matrix1)". I have changed csaslculation for Z vector, but result is alvays the same.

Code:

x = Vec1.y * Vec2.z - Vec1.z * Vec2.y
y = Vec1.x * Vec2.z - Vec1.z * Vec2.x
z = Vec1.x * Vec2.y - Vec1.y * Vec2.x

lw.writeline(Vec1.tostring)
lw.writeline(Vec2.tostring)
lw.writeline(Vec3.tostring)

Here are values for 3 vectors, and there aren't much changes if hole is horizontal or vertical = first vector has some values, but second and third are zeros.

[X=0,Y=1,Z=0]
[X=0,Y=0,Z=0]
[X=0,Y=0,Z=0]
