...Compatible with WCS points in planes parallel to WCS plane.
And based on an arc which turns counter-clockwise. And now I see (sorry again, the last days were a little bit stressing) that my first posting was not precise as it should be ...
The starting position of the problem was:
- there are three given points A, B, C
-> I can create an arc from A - B - C
-> A is startpoint, B is somewhere on the arc, C is endpoint
- The solution should be
mathematical, not using entities.
Question A (can be answered with the existing 3P-Arc functions)
- How to calculate centre and radius?
Question B:
- How to find if the arc turns left or right (clockwise or counter-clockwise)?
- How to find the included angle?
- How to find the middle of the arc?
Please consider:
- For me, I find the solution based on entities above.
- Any further solution are interesting and maybe can be helpful in other cases, but are additional work and not necessary at the moment.
- If someone wants to find a solution for this, he (or she or me) should start a new thread where the question is newly defined.
Thanks a lot!
