Sketch coords - relative to sketch or part?

Keith Rice Oct 26, 2011 10:00 AM

Hello,

Maybe I've missed something really basic, but I always assumed that if you were in a sketch, you sketched according to the part coordinate system. So if you are in the Right Plane and create a line from the origin immediately to the right, it should be going in the Z direction. But its not. Until you actually place the line, the system bar at the bottom says that you are going in the X direction. See the attached picture to see what I mean.

Now what is really crazy is that once I place the line, and then select the end point, it then gives the coordinates with respect to the part.

Hope that makes sense. Is this always the way it has been?

Thanks,
Keith

if you look at the Z the possitive direction is to the left or pointing to you!!!!!!
put it into an iso view when you draw the line makes it so much easier to understand..

yes it has always been this way..... look at the triad in iso pos Z points to the wall behind you

Keith,
Your plane must be running in the "X" direction. I tried what Lenny suggested
and my line remained parallel with the sketch plane and the only
numbers that were chaning were the length of the line and the vertical direction
depending on the direction I was going.

Hi Lenny and Scott,

Attached are two pictures in Isometric view. As you can see, the numbers in the status bar of "pre.png" (before I had placed the line) do not correspond to the standard order of X, followed by Y, followed by Z. Then, once the line is placed and the point is selected ("post.png"), they do correspond to that order.

Start a sketch on the Right Plane. Do you not get the same result?

  For what ever reason I am not able to open your images.
  And chance of instead of posting them to inbed them in this thread?

    Scott,
    
    See the updated post or attached images. Thanks for the help.

      use jpegs, not png's

      Keith,
      Still can't see them. But as I have been sketching today I have taken notice of your
      issue and I am not getting the same results as I always have. Just the "X" and "Y"
      are showing the movement in the coordinates. Not the "Z".

        The forum has a bug that cropped up in the last day or so. Image links are not working.
        
        Cheers,

        Thanks Anna.
        There has been a thread circulating about this. It has been intermitant.

  While sketching and pulling it is using the the plane for the X, Y of a 2D plane aka vertical, horizontal. then when you have stopped pulling and just click the end point it is in the default world view X,Y,Z until you start to pull which activates the sketch vetical and horizontal again.
  
  makes sense to me

    It is quite annoying when programmatically creating sketch entities with the SWX API.
