Fixed sketch orientation

[christianherrera4MSAN]

Hi all,

So when entering 2d sketch mode, Inventor will sometimes decide to enter the view rotated 90 degrees right or left. Is there a way to always enter a 2d sketch in the same orientation?

I just never have it rotate. I manually do it. That is just me.

Hi!

I agree, this is odd behavior in Inventor.

Try to disable it and check if you prefer like that... if not, change it again.

You can disable it here:

That's the problem, it rotates on it's own. I could have a sketch oriented with up being positive y, but then when I go to edit it later it decides positive x is up. Even if I exit the sketch in the orientation I want, it will return to having the incorrect orientation. I was hoping there would be some kind of option to have a fixed/locked sketch orientation so it always opens in the same orientation.

Thanks for that, it's less jarring than when Inventor decides to do a complete 180. Holding out for someone to swoop in with a hidden option or something lol.

Hi Christian,

This is due to the way Inventor derives sketch coordinate on a given selected planar reference. On XY or its parallel planes, it works perfectly. On other planes or planar faces, the sketch coordinate can be determined by the face loop geometry, which may not be aligned to the global X and Y.

You may finish editing the sketch and right-click on the sketch in the browser -> Edit Sketch Coordinate -> realign the sketch origin, X ,and Y desirably. Another option is to create UCS and create a sketch on the UCS XY plane.

Many thanks!
