The profile to follow needs to be a child of the pipe run alignment. In other words, you can’t have it follow another profile that is defined for an alignment other than the pipe run alignment. ---

Here is the Drawing I’m trying to get the Pipe run to follow the Layout (1) profile ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/8/d8115b31cb0a321a3971cc5151a4acf1d25415bf.png) I get the same error if I change the profile to “Existing” Maybe i’m misunderstanding how the two profiles are not children if the alignment: thanks Mike C ---

The _Layout (1)_ profile you are trying to follow is part of the _a\_Test 1_ alignment, which is a centerline alignment. The pipe run has its own alignment, which will be under the Miscellaneous category. You need to create a profile view for that alignment and draw the profile there. The pipe run cannot be set to follow a profile of a different alignment. ---

This is working as I expected. I was unaware of pipe runs having a different alignment. from the pipe centerline Many Thanks Mike C.
