Users reported that it could be helpful to "customize" default preferred settings of the "Place Constraint" dialog box (Type and Solutions).
In fact, adding constraints in an assembly is a very frequently used operation and the possibility to customize the default settings ("type" and "solution") of this box could be really time saver.
Adding customization could be in Application Options or directly inside the Place Constraint dialog box.
As an example, the "solution" of angle constraint is set by default to "explicit reference vector".
And for some users, setting back by default to "referenced angle" could be very helpful.
An alternative proposition of enhancement could be that Inventor remembers the latest "type" and "solution" of constraint used.
When a new constraint is generated, Inventor could proposed directly in the place constraint dialog box the latest used "type" and "solution".
Many Thanks
Best Regards
