Question

Dynamic Clearance Measurements

I need to determine the clearance between two parts as one pivots around
another. The parts are assembled with mechanism constraints and will
move properly. I'd love to see the clearance on screen in a note and
have it change dynamically as I pivot the parts.



Best I can tell, however, I need to create an analysis feature for each
measurement I want, then create an annotation feature and within that
create a note and then enter the secret gibberish code
(&dim:FID_feature-name) to extract the dimension from the analysis
feature and then place the note someplace.



Is that it, or is there an easier way that I'm missing?

    create a simple part to part (or whatever to whatever) ANALYSIS FEATURE
    that you are interested in, create the motion analysis (movement) in
    Mechanism, then use the ANALYSIS- MOTION ANALYSIS ; selected the
    appropriate mechanism analysis and analysis feature and it should dump
    you right into MS EXCEL graphing out the analysis feature...

    Thanks...

    Well, what I thought I was going to do (described below) didn't work as
    the annotation feature doesn't update dynamically.



    Several have suggested a 'Motion Analysis' in mechanism. I switched to
    mechanism mode and selected analysis -> mechanism. I stared at the
    dialog that popped up for a bit. Couldn't figure out how do even start,
    so I went back to simply positioning the assy so that it was visually at
    the minimum distance and taking a measurement.



    I wasn't looking for any sort of detail or a report in Excel, just a
    simple number on screen that would update as I dragged the mechanism.
    Seems like I did that before, but can't remember how.

    I like to insert a point where you are concerned about the clearance.


    Run the mechanism and then select: Insert> Trace Curve


    The resulting curve can be used in a drawing to measure the clearance.

    Hello,

    actually, that is not so difficult to accomplish.

    Create a *saved *measurement (point to arc, part to part etc) that gives
    you the desired distance and then switch to application/mechanism. If
    you drag your parts, you will see that the saved measurement updates
    dynamically. This is a fast and easy approach!

    Hi,

    Yes, I believe its good to make the measurement as a feature and save in model
    tree.


    I guess you directly insert a dimension (Insert-Annotations-Dimension) on the
    model. It will be dynamically changing.

    Thanks,
    KS Jnanesha
