Look at - flip upside down -

[Anonymous]

Ok so this is not a bug or anything I think but it is soooo frustrating.
When in orbit mode .I want to get a paralell view, I press the look at
button and pick a side, kazam! model flips upside down. Why ? Should not
the positive z direction allways be UP ?
99% of the times I do this it goes upside down as it was just to annoy
me....argh!!!

Why is it then when you press isoview you allways get up "up" ?`Inventor
knows where up is but it chooses to (edited)- espacially when I have
clients standing behind me...(Allways get a comment on that, they tilt
theyre heads and say something smart 😞

I know you can press space or rmb and choose common view, but that will not
allways get you the right result if you want to look at a side that is not
paralell to the common view...see? I still want to look at it without
having to stand on my head everytime....

I know exactly what you're talking about. I have a part that appears in
most of the assemblies that we make and it has the most easily accessed
surface to select for a Look At, and of course, it flips upside down.

The way to stop this lies in how the part was created. When you create the
sketch that will become the surface you will be selecting, before drawing
any geometry, check to see the orientation of the xy axes for that sketch
(Edit Coordinate System) They can be different from the part's xy axes. If
the x axis is not pointing left and the y axis pointing up, re-orient the
axes until they agree with what you want. Now create your sketch and then
your geometry and it should be fine.

Hope this helps.

Umm.. oops. I mean the x axis pointing RIGHT and the y axis pointing up.

It flips the way you constrain it. . Had you constrained the part in
question using the opposite end it would flip as you would expect. You can
use "look at" before you constrain it to see which way it should go.
Orientation does seem to leave something to be desired. For instance: a part
being placed in an iam doesn't adjust it's orientation to look the same as
it looked in the ipt. It has to do with the way workplanes are set up, so
making a part orientate a certain way depends on which sketch plane you
start on and the direction it is drawn on that plane. One would think that
redefining the sketch plane would solve the problem after the fact, and it
will, sort of, but it won't keep the constraint to the origin when
redefining and it won't flip but one way, and that's usually the opposite of
the way I want it, from my experience. Then, assuming you have an
extraordinary amount of determination, it becomes necessary to mirror the
sketch. I remember starting a thread about this a few releases back, but
don't know if it registered with anyone.

I see your points. But, If you press look at at a part within an assembly,
the view aligns with that particular parts up direction....
I would like the view to align with the assembly, not the part, nomatter
what part surface I click look at. This way it would not matter how you
created your parts, as long as they are constraind correctly to the assembly
planes.

You see, when you select isometric view, Inventor knows what side is up- It
should deepend on the same info for "look at" - is what I`m trying to
say...

Right ... it aligns with the part. If you want the whole assembly to always
flip the same relevant direction (which it won't do automatically) when you
place the ipt in the iam, pick "Look at" on the outside face and see which
way it flips, then constrain it to the assembly that way (as long as the
part is reversible). If it's not reversible, you can extrude a basic
plate/whatever to start with, place it in the iam, constrain it so it flips
the right direction, then in-place edit something to show the correct
orientation so you can go back to the ipt or just make the part from there
in-place. It's a bit of trouble, but if you have folks commenting about the
flip, it might be worth the effort. You could also start out in the iam
using the Top Down approach exclusively. I usually work the way I said,
because I want all my parts constrained to the sketch origin (just a
personal preference).

Yes, I understand your situation. Larry is right too. I try to design my
parts with the "up" direction in mind as I design if I know I will commonly
be picking it with Look At, but that doesn't work when the same part is used
in different orientations in the same assembly.

I do wish that IV would just remember which way is up for each assembly.
Now, here's a question for you. If you edit a part of your assembly in
place, and you choose Look At on a face of that part, do you want it to
choose "up" for the whole assembly, or "up" for that part?

Anyway, I don't disagree with you. It would be nice, but I don't know an
easy way to do what we want.

Exactly, I suspect that's the reason it's the way it is: not a real good way
to do it because of the variable aspects of geometry. One of those hard
problems.

What's about using "look at" with the origin planes in the browser,
i guess that will give you the right orientation.
In sketch mode I always use "look at" with the sketch entry in
the browser to have x going right and y going up.

    One other thing to note if using look at with a user defined sketch
plane and its upside down you can RMB on the sketch plane and flip normals,
this will turn the view over but not necessarily the exact way you want.

Hope this is of some help.

I'm glad this question was raised, I have been meaning to ask the same, as I have encountered this also. Just so happens the other day I had to do a presentation to the big boys and had concerns about this issue. Fortuonately I noted a few parts that I can "look at" click on and have the complete model orientate in the correct position just for the reason that Jason mentioned. I suspected that it had something to do with the creation of the part, but was not sure, kinda workin around it.Good thread though, for me at least. Just wanted to add my 2 cents, or dos centavos.

I know there are worksarounds like many of you
mentioned, but just hoped it could be done easier in the future.

For my case, we design process plants. That is a
lot of components and piping. Now, a valve or instrument don`t allways have a
"up" side spesific. It might be placed, rotated and constraind in all possible
directions. But when you are zoomed in on that walve amongst all the spagetti
piping, it would be nice to just select one of the valve sides and have it
rotate the right way. You see, if the valve is not placed paralell to one of the
origin planes there really is no good solution to the problem. All you have is
the valve in front of you, it is not paralell to your workplane and there are no
other components that are...you now have to use orbit and grip one of the
quadrants to rotate it around ( first setting COG for the valve) guess that
will be the solution for now. Could this be on a wishlist perhaps

Thanks

I think everyone agrees with you, Jorgen ...
something like the align/rotate for drawing views, maybe. It would also be nice
if you could implement the orbit cube without having to go to the menu, as
well.

I find that there are generally key parts that I want to view over and over
again while working out assembly details. It would be very convenient if I
could look at a part face and rotate it to my desired position and then
assign a view direction to the part. The part would then take the assigned
orientation every time I look at the face. Each face could be assigned a
direction so different faces could present different view directions if
desired. This would be kind of a variation of the current view concept.
