CATIA measure along direction 2

[Xaver]

Hello, I want to measure the maximum distance between a line and a surface along the z-direction (vertical). Is there any way to do that? All I get is shown in the screenshot attached. Please note the axis system for z-direction!

I haven't dealt with complex surfaces like that so I'm not sure, but the screenshots in this post may be helpful:

Measure Between to find minimum distance between 2 surfaces in a plane - DASSAULT: CATIA products

I am trying to measure the minimum distance between two surfaces, but I only want the minimum distance within the y-z plane; I don't want the x-direction to be taken into account when calculating minimum distance. Is there any way to do this? Thanks!

Thanks! That's not exactly what I need, I want the x- and y-delta to be zero. Verbalized, it would sound like this: "Return the maximum distance along the z-direction between the curve and the surface."

I would try the "Extremum Definition" under points.
Generate one Extremum point on the curve in the Z Direction.
Generate one Extremum point on the surface in the Z Direction.
You can toggle Max/Min to get the opposite results.

Then you can measure between the two points and get the "Z" component value.

If you want a 0,0,Z dimension, then create a plane "parallel through point" through one of your two points parallel to XY (normal to Z).
Then measure from the other point to this plane.

Thanks a lot! To clarify, I want to determine the maximum distance in z (and only in z) between the curve and the surface. So I'm not interested in the lowest or highest point of either the surface or the curve. If I were to draw lines from the curve to the surface in z direction, I would try to find the longest of those lines. Hope that heps...

See if you have "Distance Analysis" command might not be available depending on which license you have.

I left projection space as 3d and measurement direction in "X" (X for this model orientation, Z for yours).

OMG, that's exactly what I meant! Thank you so much! What a shame that the normal measuring tool doesn't include that option... Thanks a ton!
