Hi everybody,

I've got an issue with post output regarding operation transformations. I found these two topics, which are quite similar, but didn't find an answer.

https://community.plm.automation.siemens.com/t5/Discussion-Forum-NX-Manufacturing/PostProcessor-Tran...

https://community.plm.automation.siemens.com/t5/Discussion-Forum-NX-Manufacturing/Transformation-ins...

Actually I'm trying to do the same thing as in first link.

When I transform an operation in a circular pattern like this.

I get these values for the first instance (Number 2)

Var: mom_tool_minimum_length = 0.00000000000000000

Var: mom_transformation_matrix[0] = 0.00000000000000117

Var: mom_transformation_matrix[1] = -1.0

Var: mom_transformation_matrix[2] = 0.00000000000000000

Var: mom_transformation_matrix[3] = 1.0

Var: mom_transformation_matrix[4] = 0.00000000000000117

Var: mom_transformation_matrix[5] = 0.00000000000000000

Var: mom_transformation_matrix[6] = 0.00000000000000000

Var: mom_transformation_matrix[7] = 0.00000000000000000

Var: mom_transformation_matrix[8] = 1.0

Var: mom_translation_vector[0] = 99.999999999999943

Var: mom_translation_vector[1] = -0.00000000000005684

Var: mom_translation_vector[2] = 0.00000000000000000

The Block is 100 by 100 mm. From the transformation matrix I get the rotation of 90 degrees. But i neither get the center of rotation nor the translation vector makes sense.

Which distance does mom_translation_vector specify?

Kind Regards

Alex

Matrix

[0..2] = [i, j, k] values of "x" axis vector of matrix

[3..5] = [i, j, k] values of "y" axis vector of matrix

[6..8] = [i, j, k] values of "z" axis vector of matrix

I think there's another variable specifying the origin (looks like it should be about (50,0,0))

Production:NX10.0.3.5 MP16/TC11.2

I'd rather be e-steamed than e-diseaseled

I am not sure, but transformed operation is just transformation of operation in NX.

It has nothing to do with postprocessing.

(Or there is some another variable but I believe not.)
