You are comparing dimensions from multiple levels. The dimensions from the two points on the push buttons are probably on the same plane where the ones from the push buttons (one level) to the corner of the box (another level) will give a different values. The Measure tool is not restricted to measurements in a 2D plane. Attach your model and someone will show this to you.

Hello,
The file is sensitive so I will not be sharing publicly.
Yes I am aware it is a 3d measuring tool. I am not sure how the two points relative to each other can show an offset in X, when comparing each point to an external reference shows no offset in X.
I do not think there actually is an offset... If I create a sketch and project the parts onto it, there is no X offset between the two parts. See attached image. Happy to hear your thoughts when you compare this with the video.
Peter.
I do not think creating a sketch and projecting the two points into is is a valid test. A sketch is automatically on a 2D plane and the points will automatically only show the same X value. You can copy and paste to a new model the components in question and attach it if you want to so we can get the model. Other than that, the Forum users are blind and up to your interpretation of the measurements.

Ok, I could not use "create a copy" and then link to that for whatever reason so I had to export them as step, then import back. Joints disappeared so I just made a rigid group.

I definitely know that measure is 3D, the point of the sketch was to compare in the X axis only, not in Z (the sketch moved everything to the same Z plane).
The model is a 4th axis tombstone, the black parts are being machined. I am making the pocket for them to sit in, but started to question whether or not the parts (black clamp parts) are square (aligned?) to each other despite them being positioned by joints (tried all different joint origins and types and I get the same result). They should be in the same Z plane (which they are), but their alignment in X is confusing due to the results of the measure tool.
So when you compare two vertices (in green circles) on the two clamp blocks together they show they are not aligned in X (left and right, in red).
BUT when you compare those two vertices individually to the same corner of the tombstone they show that they are aligned in X (left and right).
I get strange results depending on which point I pick first. The screenshots above are with selecting the corner of the tombstone first.
I hope the point I am trying to make is clear here, One way of measuring shows the two blocks are not aligned in X, and the other method says they are. The tombstone is also verified to be aligned with the origin (so the X sides of the parts are in line with the X axis of the origin).
Regards,
Peter.
The Screencast will present my explanation why you are getting an X value when you measure between the two point on the black blocks. The points your are using are at a very small angle to the white component, which you call the tombstone. The edge of the tombstone is square to the model origin and therefore you will get a different X value measure from the corners of it and the two points you are measuring in the black blocks.
