Sketch Orientation; "Look-At" Feature

Status: Accepted

Autodesk, please fix your broken "Look at Sketch" feature, which currently rotates the camera in asinine fashion such that your little labeled viewcube is upside down, where "up" is actually "down".


When I create a sketch on the "right" plane, the "look at" feature should cause 'up' to be 'up' (RIGHT should be right-side-up on the viewcube).  When I create a sketch on the top plane, down should be forward (TOP should be right-side-up on the viewcube).


This problem has been in existence for at least four years with no fix.  This seems like an exceedingly simple problem. Please fix the problem.

Funny, I never bothered to post about this because I thought it was something I was doing wrong.  I hope they fix this, it's very aggravating.  Thanks for posting it.  (Again.):smileyhappy:

Augh, this continues to cause frustration.  Moments ago I created a sketch on a surface, looking at my model in more or less the "RIGHT" view.  Inventor drew the sketch and then sucessfully "looked at" the sketch with the correct orientation; RIGHT is rightside up, in the up-is-up orientation. Yay.


Well, then I realized I actually wanted to offset that sketch from the surface I originally drew it on.  Inventor won't let me drag an offset plane from the "redefine" dialog (why not?) So I created a work plane by clicking my surface and dragging to offset it from the surface... then I redefined my sketch on it... which Inventor promptly proceeded to rotate by 90º!




One thing this does seem to cement to me is that it is indeed the "look at" feature that is borked and not talking to the viewcube (or the user).  The sketch drawer can't really help itself; I understand that Inventor wants to keep Z and Y and X in the same direction, and that when I'm on the left face of a part at least one of those vectors end up reversed from the right face.  But Autodesk, surely you see that the user does not want or need to have the view orientation itself flipped with the CS each time we change sides, especially if we have gone through the trouble to remap the view cube already!  I don't think the user cares much about X and Y and Z for thier own sake; I care about meaningfully interfacing with my model and naming my views what i want in a consistent manner.  XYZ is a last-resort when I need an objective frame of reference.  


I'm not asking for inventor to actually draw the sketch in an impossible "up-is-up" CS orientation every time, whether or not I'm on the left or the right or the top; but I am asking that the view the user is presented with be put through a transform that corrects it such that the up-is-up orientation is what I get to work with.  If I create a sketch on a surface, I want a view that has the smallest possible combined angle between a named-view-zero (in "up-is-up" orientation) and a view normal to the sketch plane.


In summary:  The viewcube is great. The viewcube in intuitive. Please abandon XYZ as a view-governor to the greatest extent possible; the viewcube does that better.  In most cases the user does not need to see XYZ when the viewcube is working properly.  Currently "Look at" is encouraging a needless fistfight between the UCS and the Viewcube.  Let the viewcube win.


Just for fun, I'm taking a break:

I speak english; Inventor and the UCS speaks technobabble. But! we have an interpreter: the viewcube.  The viewcube sure seems like it is designed to translate technobabble into english, and it does a great job at doing so.  I talk with the viewcube and we communicate very nicely together.  Then I tell inventor I want to draw on it's right face, and what happens?  Inventor nods it's head, covers the viewcube's ears and mouth, then speaks to me in Technobabble.

Changed my mind.  "Look at" works great.  What is needed is not a "User-View Orientation transform" but rather a "Sketch CS Transform".  The view transform is insuffiecient becuase of what happens to sketch text.  Reorienting the view, while better than the status quo, would still leave inventor drawing 90º or 180º rotated text on sketches... which happened to me this morning, and is what changed my mind.

Update: the text issue is a pain, but text is only rarely used in sketches. The major cause of pain for most users has got to be the trail-and-error nature of using Horizontal vs Vertical constraints. 


Also, given that fixing this is going to require a complex and somewhat intelligent CS transform (or at least a CS check) for every single new sketch, this is not really a 'simple problem' and I regret the snarkiness and dismissiveness of my original post.


Nonetheless, the annoyance and time waste factors are large.

I wonder if this is related to the horizontal and vertical constraints meaning one thing when you're working on sketches on XY / XZ and something entirely different when you're working on YZ?

Sweet!  Once again, it's a more complicated issue than I thought, and I apologize for the aggressive and angry nature of the first post.  It has generated lots of frustration, though.
