Automatic update of constraints
Automatic update of constraints
(OP)
I'm haing a brain freeze moment. One of my users has got an assembly of gas springs which he is constraining to sketch curves, datums and axis to imitate the opening and closing of the engine cover. However when he edits the angle of a curve or datum to which a component is constrained, it moves, but the component doesn't. All the delay options are off in tools --> update, but still still the parts will not move. However, if i togle the constraint off then on again, it updates, also if I then go and switch on delay assembly constraints, then change the angle of something, I get the yellow exclamation mark in the constraints list which I can right click on and say update. So what I want to know is which setting have I missed which ensures a component will update when something to which is constrained is moved?

No, all parts are fully loaded and the load options are set accordingly.

...dialog, but you seem to already be aware of this so I assume that's not the problem.
I don't know what to say. Give my simple example a try (change the value of the expression 'Ang'

need to redfine assembly constraints.[strangely if you select move it will show correct position]
need to run Tools- Update everytime .
the same assembly used to run properly for some time [without manual update] don't know what happened now..
ps - parts connected thru interpart expressions..
