There have been a lot of questions around Copying Inventor designs on the Autodesk discussion groups, so I thought I’d put together this guide for you.
If you are new to Inventor, you can get tripped up when it comes to copying an Assembly (IAM) file. This is because an IAM file only contains a list of links to other Assembly and part files.
If you want to create a copy of an Assembly, you also need to copy all the Sub Assembly and Part files (Components) that go with it.
And that’s not all. If you are copying files within a Project, you will also need to re-name all the components, otherwise Inventor may find the wrong version of the component that you intended to be used in the new Assembly.
And that’s not all! An Assembly file contains a list of Hyperlinks to other Assembly and part files. If you copy, move and rename all the sub components of an Assembly, you will also need to repair all those Internal Hyperlinks.
Note: Some of these techniques can also be applied to copying Drawing files (DWG or IDW)
That sounds like a lot of work!
It can be! So it’s worth considering your options before you start.
Six Seven methods to copy an Autodesk Inventor design file (that I know of).
- Use the Vault’s ‘Copy Design’ tool
- Use Inventor’s ‘Copy Component’ tool
- Use the Inventor Design Assistant
- Use the iLogic Design Copy Tool
- Use an iAssemby instead
- Use iCopy
- Use the Copy Design tool from the SDK

Copying Assemblies with the Vault ‘Copy Design’ Tool
Copying Assembly files with the Vault is very simple, apparently –
I don’t know because I don’t have the Vault…
Edit: I do now! We’ve recently upgraded to Vault workgroup 2014, and I can say – it’s awesome!
Vault 2015 has a new and improved Copy Design tool, and you can read about it here:
This is the only downside of this technique. If you are lucky enough to be using the Vault to manage your Data, then I guess you can stop reading now!
Thanks very much to Steve Bedder of Autodesk for supplying this Vault Screenshot.
To copy an Assembly with the ‘Copy Component’ tool, you first need to open the Assembly you wish to work with. To copy the entire Assembly navigate to the:
Assemble Tab > Component Panel > Copy
or right click on your selection of Components and choose ‘Copy’.
Tip: In Inventor 2015 the Copy tool has been moved to a drop down panel
You will be taken to the ‘Copy Components: Status’ Dialogue box, which allows you to chose whether to copy or reuse the components that you have selected.
You can select and deselect components from the Assembly browser to add them to the list. Hit ‘Next’ when you are happy with your selection.
Edit Filenames and paths
The next Dialogue is the ‘Copy Components: File Names’ Box. This dialogue gives you a lot of options to chose where you’d like to save your copied components and what you’d like them to be called.
You can use the ‘Prefix’ and ‘Suffix’ boxes to Automatically revise your file names, or you can edit each one by hand.
Right click over a field in the ‘File Location’ column to set a new path.
- ’Source Path’ will save the new file in the same location as the old file (probably not a good idea!).
- ‘Workspace’ will save the new file in the root folder of your workspace (Again, probably not what you want!).
- ‘User Path’ allows you to set your own path. Copy and paste is your friend here.
Tip: Right click over the ‘New Name’ or ‘File Location’ fields and choose ‘Find and replace’ to quickly edit repeated text strings.
Finally, you have the choice whether you want to place your copied Assembly into your current assembly – or create a new file (Probably create a new file).
Hit OK, and Inventor will create a new copy of your Assembly, including copies of all the assembly’s components, and handle all the Internal paths. Very neat.
Inventor’s Copy Assembly tool is pretty easy to use and gives you a lot of useful options to re-name and path your components. Unfortunately the Copy Component tool’s major downfall is that it doesn’t recognise derived references in part files.
Design Assistant is a standalone program that can be opened from inside Inventor or started up separately. The Design Assistant uses the Inventor Apprentice COM server to edit Inventor files without having to have Inventor running.
While copying Assemblies I recommend that you close Inventor down and open Design Assistant separately.
Look for Design Assistant under:
Windows > Programs > Autodesk > Autodesk Inventor > Design Assistant
Note: When Design Assistant starts up, it will be using the last project that you had open in Inventor. Check that this is correct before you start!
Set your Project file.
Before you start, make sure that you have the correct Project file active. Go to:
File > Projects…
And make sure that the project is active that contains the Assembly you wish to copy.
Open an Assembly to Copy
Click on the ‘Manage’ button on the left, and then click on the ‘Open’ button at the top to open your assembly.
Note: Notice that the ‘Tree’ layout shows the relationships between the components – including the references of derived parts.
Set an Action
Right click over the ‘Action’ column and choose ‘Copy’ to copy a component. You can pick multiple components from the left hand column before you pick an Action.
The note in the ‘Modified’ column will change to ‘Requires Edit’ and the Cells will change to an Orange colour to remind you which ones need editing.
Edit the Path and File name
Double click in the ‘Name’ cell of the component you wish to copy, browse to your new path and rename the part.
You will need to do this for each and every component that is in your Assembly file (Excluding Library parts).
Notice how references of derived parts and components used in more than one Assembly are changed everywhere they are used, all at once.
Save your changes
When you have edited the values of every part that you want to copy, check it! and then check it again! You really don’t want to miss out a component at this stage, it could get really confusing….
When you are happy that you’ve edited all the components that you need to copy, and that the new names and file paths are correct, hit the ‘Save’ button at the top.
Note: Until you hit the ‘Save’ Button, none of the changes will be written out to disk.
Inventor will create an entirely new Assembly, and will create all the new components on disk while creating all the new file paths (hyperlinks) inside the Assembly file.
If you browse to the folder where you are saving the copy of your Assembly, you will see all the little parts being created.
After the new Assembly has been created, Design Assistant will automatically load the new version of the Assembly.
With a really big Assembly this process can take a little while – Plenty of time for a Cuppa.
Creating all those new component names and paths for a large Assembly can be really tedious, however If you need to copy an Assembly that has been created using the Skeletal Modelling technique or Master part Modelling technique, this might be the only way of copying your Assembly (Not counting the Vault).
Tip: use ‘Pack and Go’ to copy the entire Assembly out to a ‘Work in progress’ project location and then use the Design Assistant to rename, rather than copy your components.
This saves time and effort, because you don’t have to browse to a new file location each time. When you are done, you can copy the entire set of files back into your Project location.
The iLogic Design Copy tool was introduced in the Inventor 2011 Subscription Bonus pack 1, and from Inventor 2012 is in the box.
The iLogic Design copy tool was introduced to help copy Parts and Assemblies that contain – or reference iLogic’s .ILOGICVB ‘Rules’, but you don’t have to be copying an iLogic Part or Assembly to take advantage of the tool.
Starting up iLogic Design Copy
The iLogic Design Copy tool is found under the ‘Tools’ tab > ‘iLogic’ panel
Note: The iLogic Design Copy tool is only visible when no other documents are open!
Selecting Files to copy
The iLogic Copy Design tool’s dialogue takes a very different approach to the Copy Assembly tool or the Design Assistant.
A series of ‘Tree’ browsers allow to you to pick in ever finer detail which files you wish to copy.
- Use the Files to copy tree to pick the folders where the parts are stored (Remember to include Library folders in the search).
- Use the Assemblies Tree to pick the Assembly you wish to copy
- The Parts Tree will be automatically filled out, but you can add or remove individual files at your whim.
- Use the Non-Inventor files tree to add any other relevant files to the selection set.
Renaming the Files
The iLogic Design Copy Tool is a well thought out departure from the previous examples. The fact that the component names can’t be changed in their entirety feels limiting, but I guess that if you know about this and plan for it in advance it shouldn’t be a problem.
Thanks very much to Mark Flayler of IMAGINiT Manufacturing Solutions for bringing this new tool to my attention.
Much like iParts, iAssemblies are table driven configurable Assemblies that are great for when you have a limited number of variations to a design – and you know what configurations you are going to need in advance.
You can use an iAssembly in one of
two three ways;
You could use the iAssembly on its own, as a ‘Drawing Factory’. When you create a drawing from an iAssembly you can chose which of the iAssembly configurations you want to document in the drawing. You don’t need to create a new copy of the iAssambly (and it’s components) each time to document the different versions of the design.
You can also use an iAssembly as a sub assembly within a Master Assembly. The iAssembly will reference the correct configuration of the parts it contains, so you don’t need to create new copies of all it’s components each time.
Tip: iAssemblies that contain iParts which have Custom columns can have new members added to the iAssembly on the fly as the iAssembly is inserted into a Master assembly. You could use this technique to generate entire assemblies!
If you do need to copy an iAssembly (Perhaps to create an archive version before you make changes to the iAssembly table, or the components that belong to the iAssembly) you could use Pack and Go. Other wise you will need to use ‘Copy Assembly’ or the Design Assistant, as described above.
If you know in advance that you will need to create a limited number of variations of a design (Think Kitchen units), it is worth investing the time in creating iParts and iAssemblies. This will save you time and effort down the line.
iCopy is slightly different from an iAssembly, in that the iCopy factory assembly uses the skeletal modelling technique to create infinite sizes of a design.
iCopy assemblies are used in conjunction with a ‘Skelton’ part (much like the Frame Generator). iCopy handles the creation and naming of the new assembly file and all it’s component parts.
iCopy can also be used to automate adding patterns of Assemblies, like rungs on a ladder or curtain walling panels.
Like iAssemblies, iCopy is great if you know in advance that you are going to need a number of variations of a design. iCopy is much more flexible than iAssemblies and can be used to quickly create infinite sizes of a design (Think Doors and Windows).
Note: There is no reason why iAssemblies and iCopy couldn’t be used in conjunction with each other (although the thought is pretty mind boggling!).
Tip: Check out this iCopy Tutorial for more details on how to use this tool.
The ‘Copy Design’ tool is part of the Autodesk Inventor Software Development Kit (SDK). This tool has actually been developed as an example for people wanting to learn how to use the Inventor Application Programming Interface (API).
Strictly speaking, Copy Design is not intended for the general user, and you will have to load it yourself.
The Copy Design tool uses the Inventor Apprentice COM server (Just like the Design Assistant), so you don’t have to have Inventor open to run it (in fact it might be safer if you don’t have Inventor running at all).
To load the SDK, close down all your programs and navigate to:
Note: This is the location for Autodesk 2012 running under Windows 7. The SDK will always be found in the installation location for the current platform and version of Inventor.
Double click on the User.MSI file to run the installer. The CopyDesign.EXE will be extracted. Double click on the EXE file to run.
The ‘Copy Design’ tool’ could better be described as the ‘Copy drawing’ tool in that you need to pick a directory file that has a drawing file in it for the Copy Design tool to work.
Note: The original drawing file must be an IDW. DWG’s are not recognized by the Copy Design tool.
The Copy Design tool will copy any IDW’s it finds in the ‘existing design’ folder into a new folder of your choice, and it will prefix the components names and re-map the hyperlinks if you ask it nicely.
Because the Copy Design tool runs outside of the Inventor process it works extremely quickly, however the component renaming abilities are extremely limited.
Having to insert an assembly into an IDW file for the Copy Design tool to recognize is no great hardship, but if you use DWG files this tool is no help at all.
How to copy an Autodesk Inventor Assembly – Conclusions.
Like all things Inventor, it pays to spend some time planning on what you are going to do with your Assembly before you build it.
Design Assistant is OK, but I wish it had the Copy/Paste and Find/Replace tools of ‘Copy Assembly’.
Copy Assembly is OK, but I wish it recognized components from my derived Master Part based Assemblies.
iCopy and iAssemblies are great for what they are intended for – but iCopy is difficult to apply retrospectively, and iAssemblies can be limiting.
I am extremely encouraged by the iLogic Copy Design tool, and I am looking forward to using this new tool in earnest.
On the whole, there are lots of techniques for Copying Assemblies in Inventor and none of them offer a ‘One size fits all’ approach. I hope that I have helped you to understand your options so that you can make an educated decision the next time you go to work on a design!
Did I miss anything? If you know of another way to copy Assemblies, or you would like to share your favoured technique please leave a comment.
