Is there a way to use either an input value or the scale tool to set the Len value of a DC?
So the problem is that if you are needing to set values for attributes XYZ or LenXYZ and particularly if you need to use a formula to do that but you do not want them to be fixed.
For example: sometimes the X position needs to be defined based on user input but you still want the user to be able to move the object without it snapping back to the defined X position.
… Or be able to scale it without snapping back to the defined LenX
The answer as best as I was able to determine is that any components that need those attributes fixed should be placed as a sub component where the parent has floating values
It is also possible to make the XYZ or LenXYZ user editable by using the visible option window but you can not make it equal some other variable -for example var =5 LenX =var+2 would lock LenX to 7
But if LenX was user editable it would work as the primary parent
