Viewer is still 32 bit so it will install on either x86 or x64.
To set up for measure/markup in Viewer, you need to open the SE file in V&M and save it as a PCF with those options set in the Security/Password options.
IMHO I have to disagree Your statement.
For a couple of version the measurement is available also for non PCF files.
So You directly can open any SE file and You can use the measurment tools in free SE viewer.
See picture from SE viewer with an original SE part.
after sending my last article, I have seen that the question was regarding View&MarkUp and not the free SE viewer.
But the content still is true for the View&MarkUp too.
See toolbar for measurement in V&M
You have to decide wether You want to have the measrument from points or edges, for a single eleemnt or for two elements and then select the items, followed by the placement of the dim.
It's a pretty awful tool for measuring. The interface is awkward and you don't know for sure what you're picking because, unlike in SE, the entities don't highlight until after you pick them.
Yes this is absoluteley true!
And AFAIK the measurement points might be based on a triangulated boundary,
what also is regarded with the "~" sign in front of the dimension value.
But maybe this only is true for a PCF type of document.
I agree that is terrible for measuring. Is there a better way for non Solid Edge users to take measurements on a DFT file? We have the Free 2D drafting pkg loaded, but they cannot place dimensions on true SE files. I have found a workaround - save as a dwg and then re-open the dwg file, but that's sort of a PITA, but it does work.
