Sketch Does Not Rotate View Consistently

[Anonymous]

Create a new part

Click "Start 2D Sketch"

Click on the XZ (Top) plane

Watch as the view rotates to "look" at the sketch plane, but does so such that the plane is rotated 90 degrees. What is technically vertical is now rotated to be horizontal. Every. Single. Time. I don't remember Inventor 2014 behaving like this.

This complaint goes hand-in-hand with my other complaint, which is that horizontal is vertical on the left and right faces of the view cube (the constraints are flipped). It's frustrating because I have to constantly check "Am I on top view? Is my vertical constraint making things horizontal because the view cube rotated itself or because I'm on a left or right face?"

I make a fair number of bent sheet metal parts, and Inventor doesn't seem to care what the view cube orientation should be (according to the view cube text); modifying a sketch just moves the view to whatever is "closest" to the existing view. It can rotate the view to put a face right side up, upside down, or sideways. 

I would like it if every time I go to a sketch I get the view that the sketch was created on. If I make a sketch clicking on the "Top" of the XZ plane, I want the view to adjust to make Z up, X horizontal, and to look at the model from the +Y side of that plane every time I go back to edit that part. What's especially frustrating is editing a sketch and having the view rotate such that the body of the part is between the camera view and the sketch plane. Then I have to rotate the part 180 degrees to get the proper view.

Hi! Chuck,

What you are seeing on 2015 is the default "minimum rotation" behavior. The option is helping to avoid unnecessary rotation of sketch coordnate system when the sketch is placed on a face. The behavior is indeed different from 2014 or earlier. If you prefer the old behavior, you can change it back. Go to Tools -> Application Options -> Display -> scroll to the bottom -> select "Align with Local Coordinate System" -> Apply -> OK.

Another option you might consider is to create UCS before creating a sketch. This will ensure the exact orientation you like.

Thanks!

That works, thanks so much!
