Using Fusion 360's "Paste New" to create Similar Parts

Before diving into my next post, I wanted to say that I'm glad the solution I shared to fix the broken threads issue in Autodesk Inventor helped so many.  When it first occurred earlier this week, I thought it was just me.  Little did I know that so many others would run into it!

I originally found the issue on the Autodesk Community, so credit where credit is due.  The link to the post where I found the information is in the original post, as well as linked here.

Now, I'm back to a little Fusion 360 work I've been doing.

As part of an ongoing project, I've been slowly building different parts here and there, mostly off of vintage prints from AirCorps Library

One of the challenges I ran into was building a model of a continuous, or piano hinge.  It's based on the AN951 standard, which has since been superseded by the MS20257 standard,

One hinge leaf.  A little examination shows how it's mate has to
vary to mesh correctly.

Modeling the hinge isn't a difficult task, building the individual hinge leaves is easy, but they need to be made to mesh correctly.   That means the hinge knuckles have to be offset, and that's where the knuckles have to be different.


But other than that, everything is the same only the hinge knuckles vary.  So it would be ideal to be able to create a new copy of the existing hinge leaf, and make the appropriate changes. 

It turns out that Fusion 360 has a functionality known as "Paste New", and it's exactly what I needed.  It will create a new, independent copy of first hinge leaf, while leaving the original alone.  That means being able to reuse as much of the design as possible, while only changing what has to be changed.

I started with an assembly with one of the leaves modeled as its own component.  You can see that in the browser..  Now it's time to make the other side of the hinge so it can be changed so it can mesh with its mating hinge leaf.

 All that needs to be done is to right click on the existing component and choose "Copy".  It's just a good old Windows Copy.

Copying the part is where it all starts. 
Now move the cursor onto the modeling canvas, right click, and choose "Paste New".  A new, independent, hinge leaf can be placed and positioned. 

Pasting the new copy using the Paste New command
I'd suggest getting the part as positioned in it's "nearly" correct position.  Then you'll be able to make changes to key features, the hinge knuckles in this case.

Positioning the part. You can use the handles, or dialog box.
Now all that's left to do is activate the new copy, modify it so it meshes with the original, and assemble.  And we're off to the races!

There it is!  All done! 

So keep this in mind when you have similar components to build, and modify it for your needs.  It can really help in not recreating extra work!

  1. when i right click, there is no paste or paste new option. any idea why this might be missing from my program?

    1. I had to try it again to make sure a recent update hasn't changed anything. The one thing I did notice is I had to make sure the original part wasn't selected. It changed the context and didn't give me the paste new option.

      I hope this helps! :)
