library features not behaving 3

[roadapple]

I am trying to use my library features, which are API 6A flanges. They will typically insert with no problems as long as I do not deviate from the orientation from which they are created. However, if I want to use a flange on each end of a part, then one side will work and the other side will return an error message that states: Unable to create library feature with selected references.

The funny thing is that all the geometry is in place and correct when this message appears. Once I click “OK” the geometry disappears – I and the placement routine starts over. I have forever wrestled with these problems since we switched to Solidworks from Pro-e.

Does anyone have any suggestions?

I would like to thank you guys for taking the time to look at the example that I made up. I have a couple of additional comments, but I think I know how to proceed with them now.

CBL
The base part was intentionally empty as I was going for as simple of an example that I could reproduce the behavior in. As the library feature is just a sketch, I do not think that it is an issue of multiple base features. The behavior that I see is when I insert the library feature with the placement plane as Top and the Right plane selected as the Right reference, the library feature inserts ok. When I insert it with the placement plane as Top and the Front plane selected as the Right reference, the library feature inserts, but the resulting sketch gets flagged with the warning triangle and is considered not updatable. Does it not behave this way for you?

I removed the locating constraints and used the edit sketch button to specify the location and was able to achieve the desired behavior. This is conceptually different than how I was trying to use the library feature. I was trying to push the method of locating the feature into the feature definition. Your way leaves locating until the placement step. In addition to providing more flexibility in the placement of the features it has the added bonus of working. I will try it that way in the future. Thank you.
