-The trenches are cleaved and their profiles inspected in a SEM. Instead of adding a ton of measurements to each SEM image while at the SEM and hence spend an unreasonable amount of time there, I prefer to do the measurements afterwards: Opening the images with Irfanview (or any other image viewer with the same possibilities) and drawing squares (the pixel dimensions are shown in the top) as measurements. These squares are one pixel wide compared to the 2 (or even 3) which are default for the annotations in smartSEM.
+Many users make measurements using the annotations in the SEM. However, instead of adding a ton of measurements to each SEM image while at the SEM and hence spend an unreasonable amount of time there, one can postpone making the measurements till afterwards. The only requirement is that the pixel size of every SEM image is known - one can add it to the datazone: See any SEM manual for instructions.
