Help with saving out parts, derive, export, or save as

BillGEGHV — Fri, 09 Jan 2026 19:40:09 GMT

Hey All,

I could use some input on 2 project files I have for my Airsoft AR-15 upper and lower receiver build which are for CNC. In both files I have multiple components as part of an assembly. At this point I need to save out the upper and the lower into individual part files and move on to version 2 of each part/assembly. Ive watched several videos on configurations and derive but I’m unsure of what is the best way to move forward. Also, considering IF just using export is the way to save out each of these parts. Ultimately, I will need 2 of each of the upper and lower and they will need to be completely independent of each other with no associative link/s to the original master file/s. They will have features and changes independent to each version. So basically a version 1 and version 2 type of thing. Both files will contain an upper and a lower for the different assemblies with different functions. Im just really unsure how to move forward, I’m afraid I’m going end up with all kinds of problems if I don’t get this right, I don’t want to chaise my tail.

In the case of the upper file there are 15 components currently in the file and I would like this current file to be version 2 and keep everything as is, so basically no changes to this file. I then need to export, save as, or ?? to ONLY the upper part into a stand alone file.

As for the lower, this is file I did all the modeling as well as all my CNC set ups, fixturing for many different operations and all the CAM programming in. The file eventually grew to an abomination, and HUGE file I would also like to clean up. I will need to save out just the lower part and make changes, this version will be a component of my version 2 as explained above for the upper.

With all the options in Fusion for this what is the best way to get to my desired result?

Hi Bill,

If I understand your request correctly, you may simply save the the upper component as a different design (assuming there are no linked components and every component is local within the design). For the lower one, you may use Derive command to bring the body to a brand new design and then sever the link back to the original design.

Many thanks!

Hi Johnson,

Thank you for the reply. I was starting to think I would not get an answer on such a basic question. Fusion's saving options are kind of confusing!!

Do you mind if I DM you directly I would like to send you some screenshots to clarify what I need and make sure I get this right before I move forward.

Thank you,

Bill

The question might be basic, but the answer isn't necessarily so.

Most Fusion users don't have the discipline to create components that can simply be saved out into their own file into the data panel, without features in the timeline breaking in the new file.

A component derived out into another new component in the data panel does not contain a timeline in the new derived file. That's a limitation.

Sorry if this is redundant.

I need to retain the timeline of all parametric features to make some changes within them, as well as for future editability if needed, and then add some new features that the orginal dose not or will not have. This second version needs to be a new, independent, standalone file that will not reference the original in any way. In addition, edits to the original must not change the new part file.

SO what option do I use?

Select a component in the component browser, right click, and choose "Save Copy As":

The scenario you describe is exactly what this command is intended to do. It creates a new design with no references to the original, and includes the timeline.

However... As @TrippyLighting said, for this to be completely successful requires some attention to detail that is hard to do, especially for new users. If you think about it a bit, you can understand why. You said "This second version needs to be a new, independent, standalone file that will not reference the original in any way". But, references to other components, in Fusion, is very easy to do. If you, for instance, sketch on a planar face of another ~~command~~ component (edit - sorry - typing reflex), you have created a reference to that other component. In this simple case, Fusion can cope - it will just create a standalone workplane for the sketch to live on. But, more complex scenarios are not so easily handled in a standalone design. For instance, "to object" terminations to a complex surface in another component require that surface to be copied. The more complex these inter-component references are, the less likely the copy is to be successful. There are bugs in this command, but mostly it works OK. Give it a try.

Jeff, Thank you for clarifying this and answering my quesion, much appreciated!

Do you happen to know if there is an AD document that lays out all the different options for saving, exporting, derive, configurations, and what they do in a simple bullet point list type of thing? I've been looking into this for a week so I can move forward with my project, trying to get the answer you just gave me in 1 sentence, LOL. Would be nice to have something like that for future reference.

😀

Hello,

in my opinion, for all designers who have migrated from other CADs (SW, Inventor, Siemens NX, SolidEdge,...), work with components, internal, external, you can joint, you can not joint, ... make a lot of confusion.

I think that is the best way work with new parts and save as part. Later You can make drawing or assembly from saved parts.

But if You have to work with join/combine option, it is normal that we have option to save as every solid body into multibody part (not assembly). Sometimes, i construct plastic mold tool using this method. When i split tool into core/cavity/side cores, i MUST save as part by part! I have no other option.

I migrated from other CAD and I have the biggest problem with project-components- ... sometimes I forget to open new project then i have to "catch" all my pieces in recent or wherever(i know i will cure my "childhood illnesses", but reqiere lot of time, patience and nerves). For all easy jobs I have not problem, but when i start with complex jobs I have to go through some mental preparation first.

But all praise for Autodesk Fusion team. 👏
