Hi, I'm having an issue in Fusion with a very large STEP file that was not created by me. The model contains multiple assemblies and many nested subassemblies. I need to modify specific components, but when I edit one component, the same changes are automatically applied to other components that should remain independent. There are no joints or rigid groups involved, so the issue appears to be related to the model structure itself. How would you investigate the root cause of this behavior? What approach would you take to identify whether the problem is due to linked/instanced components, the STEP import process, file format/version compatibility, or another underlying issue? Would you be able to determine the cause and estimate how long the analysis and resolution would take? Thanks.

Hello, I'd be happy to investigate this Fusion 360 assembly issue. Based on your description, the most likely causes are linked/instanced components created during STEP import, duplicated references within the assembly structure, external references, or how Fusion interpreted repeated geometry from the original CAD system. My approach would be to: • Review the assembly hierarchy and nested subassemblies. • Identify whether affected parts are instances of the same component or truly unique components. • Check for external references, linked components, and import settings. • Trace the component relationships to determine why edits propagate across multiple parts. • Recommend and implement the appropriate fix (breaking links, converting instances, restructuring components, or reimporting specific assemblies if necessary). Once I review the file, I can determine the root cause and provide a clear estimate for resolution. For most assemblies, the investigation typically takes a few hours, depending on file size and complexity. Portfolio: https://www.freelancer.in/u/CreativeDesign50 Could you please share the STEP file and Fusion version you're using? I'd be happy to review the assembly structure and provide an accurate assessment. Best regards, Kirandeep Kaur

Hello, I exclusively work with Fusion 360. Most probable cause of your issue is that the Components were Copy and Pasted instead of Copy and Paste New. This creates linked components instead of separate Components and editing 1 of them updates the other also. Based on the complexity of the assembly and models/components, I can maybe edit the Components as separately using the Paste New command. Happy to help you in any way. Cheers! - Prasad

Hi, "Same changes applying to multiple components" in a STEP import is almost always a linked component instance issue. Fusion 360 treats repeated geometry in STEP files as instances of the same component rather than independent copies, so editing one edits all of them simultaneously. The fix is breaking the instance link by right-clicking the affected component and selecting "Make Independent" before making any edits. I'm a Senior Engineer at Vercel with Fusion 360 assembly debugging experience across complex imported STEP files with nested subassemblies. I've diagnosed and resolved instanced component conflicts, broken unwanted links, and restructured assembly hierarchies without losing geometry or reference relationships. My investigation approach is to first check the component browser for duplicate icons indicating instances, then trace the parent-child hierarchy to identify where the shared reference originates in the STEP import, then break instances selectively on only the components that need independent edits while leaving intentional instances intact. Send the file and I can assess the root cause within a few hours and give you a firm resolution estimate before any billable work begins. Best regards

Hi, I can investigate this issue in Fusion 360. The behavior you describe is typically caused by instanced/linked components — when multiple components share the same definition, editing one affects all. I'd like to review the STEP file first to confirm the root cause and give you an accurate time estimate before committing to a full solution. Would you be able to share the file? Best regards, Maryan

Hello, I can help investigate and resolve this Fusion 360 assembly issue. Based on your description, my initial suspicion is that the STEP import may have created multiple occurrences of the same component definition rather than independent components. In Fusion 360, editing one component can affect all instances if they reference the same underlying component, even when no joints or rigid groups are present. However, I would perform a structured analysis before drawing conclusions. Before providing a firm estimate, I have a few questions: Approximately how large is the STEP file (file size and component count)? Which version of Fusion 360 are you currently using? Do you know which CAD software originally created the STEP file (SolidWorks, Inventor, Creo, CATIA, NX, etc.)? Is the issue affecting all repeated components or only certain assemblies/subassemblies? Can you share the STEP file or a sample assembly that demonstrates the problem? For most assemblies, I can usually identify the root cause within a few hours after reviewing the file. Once I examine the model structure, I can provide a more accurate estimate for both the analysis and the resolution. I look forward to reviewing the file and helping you get the assembly behaving correctly.
