Transformation inverse problem

[Anonymous]

Hi,

I found a bug in Transform.Inverse.

I am using Transform.Inverse on this matrix : [ 0 1 0 -29.3 ; -1 0 0 3; 0 0 1 -0.73; 0 0 0 1] and the result is : [0 -1 0 -3 ; 1 0 0 -29.3 ; 0 0 1 0.73 ; 0 0 0 1].

According to matrix inverse calculuation the result is [0 -1 0 3 ; 1 0 0 29.3 ; 0 0 1 0.73 ; 0 0 0 1].Also using the formula for transformation inverse :

http://www.cg.info.hiroshima-cu.ac.jp/~miyazaki/knowledge/teche53.html , the result is the same [0 -1 0 3 ; 1 0 0 29.3 ; 0 0 1 0.73 ; 0 0 0 1].

Thank you for letting us know that it is solved.

However, the link that you posted does not work for me.

What section of the help file are you pointing to, please?

Hi Jeremy,

I'm pointing to:

Revit API Developers Guide ->  Revit Geometric Elements ->  Geometry -> Geometry Helper Classes.

Have a nice day

Dear Daniel,

Thank you for the detailed path.

For Revit 2016, that leads me to

Wow. I just tested that link, and that one does not work for me either.

Strange.

I reported the error to the powers that be.

Another question, though: 

How did that help solve the problem for you, please?

Thank you!

Cheers,

Jeremy
