I placed the fixture in the Ceiling plan from First Floor. But the light fixture is not placing from the top of the pending part and instead is placing from the main fixture in the bottom of the family. It is supposed to be hosted on the nearest ceiling on the ceiling plan but apparently is not placing it properly. Is this an error or a bug, or what parameters do I have to tweak. Or do I really have to dig in the family editor? Why is this family placing that way when it is a premade family from the main Revit Library.
Thanks in advance I appreciate your help
Post the family. If you can't, then I would have to speculate that the family is acting out Maybe due to a bad diet or parent -- or quarantine.
when you place your component did you select place on face??etc.. thanks

What does this mean? It doesn't make sense and your image doesn't illustrate the problem.
I opened the family editor, I selected the reference plane indicated with the blue arrow, and I noticed that in the properties palette, the define origin checkbox had the checkmark. So what I did was: I selected the reference plane indicated with the red arrow and then I just applied the checkmark on "the defines origin" checkbox. That automatically removed the checkmark from the bottom reference plane indicated in blue, I guess because they are parallel to each and never intercept each other. What I'm concerned about is that this is a default family from Revit, I guess I have to upgrade to Revit 2020 as I'm currently in the 2019 version, in order to have it fixed. hehe, thanks for replying @barthbradley I thought I had to dig through all the family settings in order to fix it, but came across an Autodesk link that explains how to adjust the origin placing of a family. the origin is defined by the intersection of 2 reference planes.
Excellent detective work. I just opened the stock Revit 2020 Pendant Light - Hemisphere family and it DOES indeed have 2 Origins defined in Elevation. That's just plain wrong. No wonder it was "acting out". Bad parenting. he, he.
I was curious about that family myself and just checked my 2019 version and it appears that is was rebuilt since then. The origin is correct in that one. I'm no expert in lighting but the 2019 version seems to have problems with the light source. Maybe someone was "fixing" the light source and "decided that the reference plane should be at the light source.
I opened the family (Pendant Light - Hemisphere) right now because I did not save the previous editing and indeed, Both of the reference planes are not intersecting with each other and both have the "defines origin'' checkmark.
But once I unchecked it from one of the reference planes, now the checkmark holds on with only one of the non-intersecting reference planes in question. And let's say if I decided to apply the checkmark back to the reference plane it automatically clears away the checkbox from the other non-intersecting reference plane and vice versa.
I hope that I have explained myself well hehe. But I'm glad it was simple to fix, But now I'm wondering How do I put the checkmark on two nonintersecting planes at the same time, is it possible for a regular Revit user to do that?
I'm pretty sure a regular Revit user would know that two parallel reference planes cannot define the origin. Unless... there's a way to have more than one origin. Hmmm...
I attached the family in this reply, feel free to open It and check it on one of the views, select and review each of the parallel reference planes in question and you will see that both have the "defines origin" checkmark. It is a default Revit Family that comes with the installation of the program.
I'm still learning how to use Revit and I was doing an exercise were that specific default Revit family was loaded into the project. And it was not placing the ceiling-based lighting fixture in the correct position. I guess when a default Revit family behaves in an unexpected way it is frustrating to a beginner user as the situation gets a little puzzled.
I wasn't doubting your family. The screen shot I posted is from the 2019 family that I have. It's quite clear that it is different. Maybe from a different library, I don't know, don't really care. As far as I'm concerned it's just two more examples of the fallibility of the OOTB content.
