My sketch keeps rotating?

My sketch keeps rotating?

My sketch keeps rotating?

(OP)
Alright, so I have this project that requires me to input coordinates for the location of specific circles in a sketch on the XY plane. After finishing the sketch and saving my CATPart, everything is fine and works properly. Then after loading the CATpart again and starting a new sketch on the same plane (XY plane), my original sketch is rotated and my new sketch doesn't follow the same coordinate system.

Here is the original sketch that follows the coordinates I used as instructed by my project.


Here is the second sketch which does not follow the same coordinate system. Notice how its rotated.


As you can see from the original sketch image, the largest circle sits on the origin (0, 0). But when I create a new sketch on the same plane, I get a rotated view of the sketch and the coordinates are completely different.
Say if I chose to edit the original sketch (named sketch 6) and placed a point at (10,10) and then chose to edit the second sketch (named sketch 9) and placed a point at (10, 10). These two points would NOT share the same X-Y coordinate. Rather, the point from sketch 9 would be elsewhere.

Any help?

RE: My sketch keeps rotating?

Is the sketch rotated or is the view just rotated? Look at the trihedron on in the upper right corner. You could also use a positioned sketch. Draw a point at the origin and a horizontal line in the X direction. Make a sketch, switch it to positioned, pick the point as the origin and the line as the horizontal. You may need to flip the vertical direction depending on how it is oriented. Constrain your sketch to the H and V inside the sketch.

I,

when you create the second sketch, the horizontal and vertical axis, are switched. What you see is just a rotated view. If you want to maintain the same orientation of the previous sketch, you need to select the sketch, right click it, and change sketch supports, there you can arrange the orientation of vertical and horizontal axis.

regards

Thanks for the advice guys! Really helped!
