OFFSET CONSTRAINT

[rjkdk]

For some unknown reason after many years of use my inventor 2010 offset constraint is acting strangely.

At the moment I need to always reset the offset constraint to zero, whereas previously this was the default setting.

Have I inadvertently changed something?

Very strange

Hi, you mean the offset of the restrictions? By default this box is deactivated. It is very useful to activate it when you have a very large assembly and you want to locate a piece at a distance that you do not know but you have an idea of where to position it then the restriction will give you for example 33.2658985 and you place 33. Also if in the very large assembly you have to locate a very small piece and you do not want to be "lost" in the assembly, after placing all the restrictions you will take them all to zero

Hello there,
That is not quite the problem.
For years I could just access the "place constraint" command and select
"mate" or "flush" as needed. The default dimension was always 0.000.
As it stands now the offset dimension can be any number, the source of which
I have not yet discovered. So I must now always make sure I reset the new
default number to what is required, most often zero and not the number that
the program has selected for some unknown reason.

@rjkdk,

The way he explained it is a bit confusing, but @Sergio.D.Suárez's suggestion actually is the most likely cause.  If the box he pointed out is checked, the offset value defaults to the current distance between the selected faces, instead of zero.

If you don't know what that setting does, it would appear random, but it actually isn't.  In reality it is an automatic measurement, intended to constrain the parts at their current relative locations.

Hi! I agree with John and Sergio. If the explanation does not apply to you, please share a video of such behavior. There should be a logical reason.

Many thanks!

Hello  rjkdk,

Please have a look below mentioned solution which seems similar problems solution.
