Good day all,

Is it possible to create a user defined cylindrical coordinate system using the Calculix Keyword Editor ?

Is there perhaps any tutorial video on this ?

@FEAnalyst  
Pretty straight forward and easy to apply.  
It worked perfectly.  
Thank you.

Below is a link for further guidance:

PS. Looking forward to the day that PrePoMax can accomplish this via picking surfaces/points and the user defined axes is then displayed on the part.
