Assembly Constraints, Sweeping between limits.
Assembly Constraints, Sweeping between limits.
(OP)
Hello All, I did a bit of searching and am looking of the best way to sweep a mechanism between limits. In the past, using mating conditions, I'd often 'vary constraints' to show the sweep of something. (Is this still available in NX7.5?..couldn't find it.) Now, I usually just know the angle of the stops, and vary an expression between the angles ends (several key-ins). Or sometimes I use multiple constraints suppressing those that are not needed to show the positions. However, I want to vary an angle by sweeping (much like in vary constraints) between it's mechanical limits using the dynamic handles, or by having arrangements cycle through a range. What is the best way to accomplish this?
Regards, and have a Great Weekend!

An alternative would be to use Move Component, but in that case you may need to suppress any constraints which define the exact position of something. In your example of a part which can rotate, as long as there is nothing preventing (constraining) the part from rotating, you could just go to Move Component, select the component/sub-assembly you wish to rotate, set the Transform Motion type to 'Dynamic' and then just use the drag handle to move it. or you could pick an explicit motion type, such as 'Rotate', where you define the axis and type in an angle.

I tried going the sequence route, but I am missing something or it will not work for me. I have multiple components with different stops. In other words, one component stops but the next one needs to keep going until it stops (collides), but they share a common part that is actuating them. (It seems as if I will need redundant components to do hide shows with different assembly constraints as assembly constraints can not be manipulated once in sequencing...?)
Thanks for all your help,

BTW, even if you do not yet own the Motion Simulation module you can still review the Help files which might help you determine whether this will better address your needs and if it looks promising you might be able to convince your Siemens PLM rep to get you a trial license.

I'll look into a trial of kinematics.
