Cylindrical coordinate system

[shanghongcao]

How to turn on the cylindrical coordinate system when building a 3D model? The cylindrical coordinate P is normally given in (r,θ, z).

Another question: how to convert cylindrical coordinate system to rectangle system into (X, Y, Z)?

X=r*cos(θ)
Y=r*sin(θ)
Z=?

NX does not support a 'cylindrical coordinate system' as such. However, you can enter Points using so-called 'cylindrical coordinates' by going to...

Insert -> Datum/Point -> Point...

...and in the section of the 'Point' dialog titled 'Offset', set the 'Offset Option' to 'Cylindrical' and you will find your (r,θ,z) entry fields.

Thank you, John
What can I do if there are thousands of these points and the coordinates are given in an excel file?
Please find one coordinate file attached.
How can I import these points?

Write a program. That's why we offer as many toolkits as we do since we can't possible provide a built-in function for every possible 'interface/exchange scheme/converter/data reader/etc' that could be dreamed of my man.
