Best way to know the distance between parallel planes

[[Ch...]]

I have a revolved part with planes at the ends. And I want to measure the overall length by measuring the distance between the parallel planes. What is the best way to achieve that?

"Two Point Distance" in "Size-Standard" Menu is one way to do as per my understanding. But I don't know how does it works concept wise (symmetry plane and stuff)?

Secondly, Is there any way to find the axis of the part? I mean as a characteristic. Then I can find its intersection with the planes.

Your help is highly appreciated as I am fairly new working with Calypso.

What do you mean by axis of the part? What measurement are you wanting to get? If the part is cylindrical, you would measure it as a cylinder, and there will be an option to shell the cylinder when creating an intersection using that feature.

Thanks Justin for the link.

The part has a random curvature along the length with flat ends. So If I can find the intersection of axis with both the flat ends. That would give me overall length.

The majority of thickness measurement were/are handled with the Cartesian Distance (Perpendicular Distance works as well if you know how to setup the Feature correctly).

The way that Cartesian Distance works is that Feature 2 is the Feature that is the reference feature (setting plane), and Feature 1 is the Feature that is being evaluated in reference to Feature 2. It is creating a distance from Feature 1 that is Perpendicular to Feature 2.

Symmetry Plane is great for being able to check fit/function, and as of 2021 being able to calculate the LP and Envelope directly.

The thing to remember about Plane to Plane measurements is that you are assuming that they are parallel, but in reality they are not.

...which is why I use caliper distance for measuring planes. You can set to min., max. or centroid distance and you can use secondary alignments, both of which allow a more precise functional check.

The Caliper Distance can work well or it can work against you.

Measuring a distance between two planes via the Caliper Distance can work well for small planes that are far apart, but I don't know if I'd want to use it for functional checks.
