Hi All

I do not have knowledge on creating library features. I just stared to create library feature for O-ring groove. I am pasting the steps that I have followed while creating a sample.

Step1. Created a basic shaft

Step2. Created a Groove profile and made revolve cut and saved this Feature as library feature

When I try to drag and drop the the library part on some part it asking for reference as I seen in image

and I selected the same, then it is saying unable to create library feature with selected reference.

I searched in internet and found one O-ring groove library file, when I drag and drop it, it is asking for the locating edge and OD. Could someone just check and let me know how it is created.

Thanks in advance
