Why doesn't 'Snap to middle of 2 points' work the same way twice?

I wanted to draw a line up the middle of 2 cylinders (water tanks) using 'Snap to middle of 2 points'. It didn't work.

So, I created a horizontal line below the tanks as an experiment. I can successfully use 'Snap to middle of 2 points' on the line, but not when I attempt to use the centers of 2 cylinders.

Why?

    Some codec issue prevents me from watching the screencast. But my guess is that you have DUCS switched on.

    Roy:

    DUCS is on.

    Help me understand - how does that affect getting to the mid point between 2 points? Those points are in 3D space regardless of how the UCS is set.

    Also, I downloaded the screencast to my box from the web site and it plays on my box so the file is OK. It's an MP4 I created from a default screencast .webm file format using VLC Media Player. I do that conversion because when filing a bug report that system refuses to accept .webm files. Can you play other mp4 files?

    Basically points are acquired in the current UCS. If the UCS changes during 'Snap to middle of 2 points' the resultant point will be unpredictable.

    I can usually play MP4 files.

    OK - I get it. When the UCS changed it destroyed the first points reference leaving only the second point which is where the line started.

    I tried it without DUCS and it worked fine, so your educated guess was correct.

    Thank You

    Ran into that too.
