I use Vision Assistant 2019, 32 bit.
When I have 2 points from Find Circular Edge, I use Caliper: Line Fit, to make a line from that 2 points.
And then Set Coordinate System, using angular motion mode, which the only X-axis angle that I can refer to is the line from Line Fit.
Finally I saw that the X-axis angle is not related to the line that I refer to.
Is there any explanation?
Or is there other method that I can set the x-axis correctly to the line?
Thanks.

Hi
I had tested the Set Coordinate Function in different angles of the detected point. All my coordinate showing perpendicular 90 degree. I believe you have the Geometry setup in rotation mode, therefore your set coordinate doesn't look perpendicular.

Hi Elson,
Thank you. Unbelievable someone looked at this question.
My question may not be clear to you, so I would repeat:
1. Get two points
2. Draw a straight line between those two points.
3. Set a coordination system on one of those points, with X exactly on the straight line that just made (and Y will be perpendicular to the straight line)
You may try with any picture that has two circles.

Hi man
Can you clarify how to draw the red line? I tried the caliper but I did not get to draw a straight line between two points.

Hi,
You can use this function to build a coordinate system

Let me teach you.
Select Caliper, and then inside Caliper, select "Line Fit".

This is exactly what I want.
But it seems impossible in Vision Assistant. Or it could be a bug..
