Losing Joint Reference When Updating Sketch Parameter

[locjeffery]

Hi all,

I just watched the following of your "tutorials": https://www.youtube.com/watch?v=jWvd8l0ONOY&t=2967s

In there, it is tought to have seperate File with a Sketch that holds the cutting dimensions of the Fe-/male Connections. These files are imported into a new File to be used there as a reference. This is exactly what I with my model.

In addtion to that I have a Parameter "Spread" that regulates how far apart the two sides of the train tracks are apart (see video). Unfortunetly, everytime I update the parameter to another value, the "Joint"-Features loose their reference and I have to update these references. Since I am using this model also in another assembly, I have to fix a lot if things if I change the parameter. This can't be right can it?

I hope, that the video explains the problem better than the text 😉

In case the uploaded video does not work, I also uploaded it to Youtube: https://youtu.be/fmIb5LcAXU4 

Best Regards

Need the file.  First guess is the parameter change is for the track curve.  Pin socket Pattern was not in that sketch.

Might help.....

Hi,

here are the files.

Yes, I want to change the parameter "Spread" which should set the curvature of the track.

I hope I attached the right file formats.

Thanks for your help!

The error can be intermittent, been reported before.  Didn't break with small steps

You may have better success by joining to the swept body (if you didn't use it), than that sketch, but not sure.

Will let someone else mention fully defined sketches.

Might help....

You need a little more control on your Derived Cutouts to control the placement when you change the two parameters.  Model is attached, I will caution you to place it in a separate folder so you will not contaminate your work.  Let me know if you need help figuring out what I did but I think it will be obvious.

Thanks a lot! Thank you both!
Joint Origins did the trick 🙂 

Happy New Year!
