Change in arc start angle and end angle on 3DRotate.
I created an ARC, start angle 0, and end angle 90 degrees. Please refer to the below screenshot
Then I did a 3DRotate, from the start point of arc, about X-axis 30 degrees. I check the start and end angle it remains the same. i.e. 0 and 90 respectively. Please refer to the screenshot below.
Next I again did a 3DRotate from the start point of Arc but this time about Y axis, 30 degrees. On checking the start and end angle this time, it got changed to 49 and 139 degrees respectively. Please refer to the below screenshot.
So my question is, how come the start & end angle changed upon rotating it to Y axis, but not changed when rotating it about X axis.
I understand that there will be some mathematics behind this calculation, if someone can refer the behind the scene calculation it would be really great.
Please help me to understand this.
Thanks,
Yash
