Hi everyone!
I'm trying to create assembly drawings, but I get unexpected results depending on the assembly orientation.
I have 5 instances of the same assembly type in my project. (All the instances are of Generic Models 001 type.)
1, 2, 3, 4 gives the same result. Top view looks down at the head, Front view is upside up as expected.
However, if I select instance 5 and use it to create the views, top view looks from the head to the leg as expected, but the front view is upside down.
I'm quite sure this is a bug but I wanted to ask for your opinion before submitting.
Solved! Go to Solution.

I don't know if I'm fully understanding your issue, but I get totally different Views when I Host the Family to a Face or a Named Ref. Plane.

Usually, assembly view creation is based on the assembly origin's orientation. Blue arrow is the up direction in the assembly's local coordinate system. If you create a top view it will face opposite to the blue arrow. If you create a front view the blue arrow should point up in the view's coordinate system.
This is the general rule. My issue is that this general rule breaks when the blue arrow faces down in the global coordinate system.
@barthbradley if you double click the assembly, what direction does the origin point at? Probably not aligned to the family. Try to realign, delete and recreate the views.

I think the “fix” would be something like AGACAD, a Revit plug-in, came up with: “Align Assembly Front View Orientation with Front View Orientation in Family Editor”.

You ought to bring it up here and see if it gets any traction:

If you do, let me know. I’ll vote.

A manual half-fix is to select the crop box and rotate it 180 degrees.
Still, when opening the top view, the front view section symbol is facing the wrong way and its Far Clip offset is zero.
So to get a correct representation, you have to fix the section symbols too.
If the correct views can only be created manually then we can state that Revit's Create Assembly Views feature is broken for assemblies where the orientation Z axis point downwards.
So for me this is not an Idea Station topic because it is not a missing feature. It is a bugged feature and should be reported as an issue. I haven't done this before, maybe you can point me in the right direction if you agree.
Thanks for the suggestion, I know Smart Assemblies, been using it for a while, though not anymore. Maybe I'll download a trial later, though I doubt they hard coded a specific fix for this case.

That's exactly the same workaround suggested in an AKN Support Article addressing this "BUG" - which of course is a term they never use in these types of articles. Instead they always report "this incident is being investigated for possible cause and resolution".
Anyways, if you want to report it, open a Support Case through your manage.autodesk.com home page.
Best of luck to you.
