Simple distance measurement and Space point

[[yo...]]

Hello everyone,

I am relatively new to Calypso but already have some experience with other CMM software.

I would like to measure a simple dimension AB (see the attached photo).
This dimension involves an angle, but that shouldn't be an issue in Calypso.

To measure this distance, I follow these steps:
1- Create points A and B.
2- Configure clearance and retraction settings based on the geometry.
3- Create another point near A and construct a line.
4- Measure using the "perpendicular" function (between B and the previously created line) and select the "depth" option.

Do you agree with this approach so far?

If so, my question concerns how points A and B are captured.
I have the choice between "Touch Point" and "Space Point."

I should mention that I do not have a CAD model.

With "Space Point," the AB dimension can vary significantly just by slightly altering the direction of the i, j, and k vectors.

Which point capture method do you recommend for my application?

I hope this is clear. Thanks for your help.

I usually use Plane point - forcing vectors to nominal.

Hi Martin,

 

Thank you for your advice.

 

I set my point with a plane point but i don't see any improvement in my results they are not stables.

I noted that there's 3 different option to determine the normal:

- Probing direction

- Plane measurement always

- Plane measurement in manual

I didn't find in the manual any explanation on this matter, but they affect a lot my results and the stability.

When i choose ''plane measurement always'' because my faces are little, the probe miss the surface and then the normal vector is affected and of course my results.

 

Also, when i create my line ( i attached a figure), the line is not connected to the 2 points.

Is it a graphical issue or a problem in my construction?

 

Thank you for your help.
