Sketching angles question

[LibertyMachine]

I'm wondering if perhaps I am doing something wrong.

When working in a sketch, I would draw a line and specify an angle that I wanted it to be at. Now, one would think that the angle is locked into how you are looking at the part, not how the part was oriented. So, 3 o'clock would always be an angle of zero, due north would be 90, so on and so forth.

However, I find that when I start drawing sketches on the sides of parts, or on the bottom of a part, the angle actually ends up getting inverted and then I have to start doing some calculations to make sure that I am drawing in the proper direction.

Operator error and working as intended, or......?

@LibertyMachine,

When sketching the length and angle are shown.  If you type in a value and press tab that will lock the value and a dimension will be created.  I have created a video of the workflow, if this differs from what you are seeing please capture what you are experiencing.

What you are descibing is Skethcing 101, and I understand what you are saying.

However, what I've experienced is this:

First sketch, select line. Click start point. Press tab. Type in a value, such as 60 degrees. Line shoots northeast, as I'm looking at the screen. Press enter, type in a length, press Enter again.

Second sketch on another surface, or with the view of the part rotated.

Click start point. Press tab. Type in a value, such as 60 degrees. Line DOES NOT shoot northeast, but might head South West, as I'm looking at the screen. Press enter, type in a length, press Enter again.

Sorry, I can't do a screencast, I'm at work

@LibertyMachine,

Thank you for the workflow, I now understand what you are experiencing.  What you describe is as designed, the angle that is created when sketch is referencing the origin, along with what is positive x,y and z.   The angle does not take into account view orientation.  My suggestion would be to draw your geometry and then add dimensions.  This way you can select what the angle references and there should be no reason to manually calculate the angle.  If you believe that this should be an improvement, please add it to the IdeaStation.

I'm just a simple user, but yes, I think that it should most definitely take into account view orientation. Working in a 3D environment, you don't always get to postition things with perfect relation to XYZ and sometimes you may have to rotate the part 90 degrees (in view) to even get the relevant features on screen (working with larger drawings)

I shall toss this topic on the black hole of the IdeaStation

I've marked the post by @promm as an "Accepted Solution", only because it is the answer from Autodesk, not that I agree with the "intended flow".
When you are in a 2D sketch environment, north should always be 90, south should always 270, or -90.
I've tossed a suggestion onto the IdeaStation. And....i'ts got one vote. Maybe I'm in the minority?
