There has been an option for this as long as I can remember. Here is a link to the SOLIDWORKS 2010 help topic where it is listed as the very first option:
and that same option is in the same location in Tools, Options, System Options, General in SOLIDWORKS 2018:
I believe the option existed before SOLIDWORKS 2010 as well, but 2010 is when we implemented web help, so that is as far back as I can look easily.
You can see that you submitted the ER on 5/12/2017 and it was closed 7 days later on 5/19/2017 which is probably when it was reviewed internally by someone in product definition. At that time, you should have either received a notification by the reviewer of the assigned SPR# (if it turned into an enhancement request), or in this case, to tell you that the functionality already exists. If you did not receive a notification, I don't know why. Perhaps it went to a spam folder or something?
Interesting, not a setting I was aware of.
I have recently had my registry settings wiped by my VAR tech support, so this may be a default setting that has changed over the time I have been a user.
Either way it is a welcome feature I have always used in other software so it is good to have in SolidWorks.
Thanks for the reply.
