I would like to request to have an option for a virtual ruler appear within an assembly, part or an IDW. I find myself moving assemblies or parts off to the ends of my screen to quickly double check if surfaces are coplanar, or for checking if features have draft applied, or if drawing views or annotation balloons are lined up etc. etc.. It would be cool for this type of a reference could be available without it adding any geometry or model tree entries. When you are done "checking", it would just disappear. Maybe it can be integrated within the new 2018 measure tool.
Thank you,
Stephen R.
