Flexible Library Assemblies

[Winks87]

If I create an assembly for a library, do I have to create positional reps before saving it to the library folder?  I would like to modify the overrides on a library assembly.  Is this possible?  I really dont want to lock in the positional overrides - think of a flexible cylinder assembly used in multiple assemblies.  The "extended" length of the cylinder could be different.  How to do?

I guess you have setup a non-editable library in your project file..

A cylinder could be done using constraint limits and thats it.. You don't necessarily need pos reps..

Also many people simply make a new project that allows them to edit library files..

If I use constraint limits for the cylinder assembly, does this give me free motion?  Can I constrain the cylinder rod end to another component to have it in various positions of extensions?  I assumed it being a library part I could not do this... I will try this when I have time.  Thanks for the response.

Confirmed:

1.  Create a project file that enables you to modify library parts - I did this by setting the library path as my standard workspace, no "library" defined.

2.  Create an assembly with constraint limits - I used the new "joint" command with a cylindrical sliding fit  - with limits set.  The idea is to set the limits of a moving part, but not to lock it in to one position.

3.  Go back to the standard project file and insert your new assembly - IMPORTANT - set it as a flexible assembly.  This will allow you to constrain it to other moving parts.  The best part is the sliding constraint limits - this allows you to "check" a design to see if it falls within the limits.

Thanks mcgyver!!
