Hi Pilou, for moving the text you can do that with a regular dimension by selecting it and turning on edit points using Edit > Show pts. There will be a point on the text which you can drag to reposition it. The dimension text will also automatically rotate itself to be legible in any view of it so you don't need to manually rotate it.

Well the PDF/AI file only has 2D coordinates so when you read it back in it's going to be on the x/y "Top" plane.

For your case there you could do it like this:

Select dimension, export to PDF format using "Projection view: Right", "Scale: Preserve units", 1 units in MoI = 1 cm on page, and "Center on page" off.

Next run File > Import, pick your PDF file, then run Transform > Orient > View to view and click once in the Top view and then next in the Right view to reposition the dim back to the Front view.
