Markup, measurement and section in SE Viewer works only for .pcf files. Not for SE native .par .psm and .asm files.
There is a paid version of SE Viewer called View and Markup. It comes bundled with Solid Edge and can also be bought separately. The idea is that the engineer opens an assembly in V&M and saves it as a single .pcf (packed collaboration) file for review purposes. He can send the .pcf to anyone with SE Viewer installed, without giving away the entire design.
What was mentioned by @vongahlen is correct for ST7, but you can use measurement in ST8 viewer on native SE files. Unfortunately section is not allowed in it, but I don't understand why? Anybody from developers? 😎
