Fixing the Bridge Tool Hotkey in 3ds Max When Nothing Seems to Work
If you’ve assigned the B key to the Bridge tool in 3ds Max and it’s not working — even after double-checking everything and resetting to factory defaults — you’re not alone. This frustrating issue affects many users, especially when working in Editable Poly mode.
In this post, we’ll walk through exactly why your hotkey might be failing, and how to fix it with confidence.
But first, if you’d rather see the steps in action, here’s a quick tutorial that might clear things up right away:
The Problem: Hotkey Assigned, But Bridge Won’t Trigger
You’ve followed all the right steps:
-
Opened the Hotkey Editor
-
Searched for the Bridge tool under Editable Poly
-
Assigned the B key as the shortcut
-
Clicked Assign and even confirmed it shows correctly
And yet… pressing B does nothing.
Even a complete factory reset of 3ds Max doesn’t help. It’s enough to drive anyone crazy.
Why This Happens (and It’s Not Just You)
Here are a few reasons why the Bridge hotkey might not be functioning:
-
The wrong context is selected — Bridge only works in specific sub-object modes (like Edge)
-
Keyboard shortcut conflicts — Another tool may already be using the B key
-
You’re not in Editable Poly mode — It needs to be active for the command to be triggered
-
UI mode interference — Some interface presets change how tools behave
These aren’t bugs — they’re just quirks of how Autodesk 3ds Max handles hotkeys and context.
Step-by-Step: How to Make the Bridge Hotkey Work
1. Make Sure You’re in Editable Poly Mode
Before anything else, check that your object has an Editable Poly modifier applied. Without this, the Bridge command won’t even be available.
In the Modifier panel, the dropdown should clearly show Editable Poly selected. (Refer to the screenshot if needed.)
2. Double-Check You’re in Edge Sub-Object Mode
Bridge only works on edges. So:
-
Go to the right-side command panel
-
Under “Selection,” make sure Edge mode is active
-
Select two compatible edges on your geometry
If you’re in the wrong selection mode (like vertex or face), the shortcut won’t trigger anything.
3. Reassign the Hotkey in the Right Context
Now let’s revisit the Hotkey Editor:
-
Go to Customize > Customize User Interface
-
In the Keyboard tab, make sure the Group dropdown is set to Editable Poly
-
Scroll or search for Bridge
-
Click the Hotkey input, press B, and click Assign
🖼️ The screenshot shows this process visually — note that the category must be Editable Poly or the assignment won’t work in that context.
4. Check for Key Conflicts
Use the same Hotkey Editor to verify that B isn’t already used by another command.
If there’s a conflict, try another key temporarily (like Ctrl + B) and see if that works. If it does, the issue is likely a conflict or priority issue.
5. Be Aware of UI Mode Limitations
If you’re using a different workspace like Design Standard instead of the Default UI, behavior can vary. Try switching back to Default UI temporarily to rule this out.
Final Thoughts
This issue is frustrating, but with a little troubleshooting, you can get your Bridge hotkey working smoothly.
✅ Make sure you’re in the right modifier and sub-object mode
✅ Assign the hotkey in the correct category
✅ Avoid key conflicts
✅ Double-check your UI mode if all else fails
If you’re still stuck, don’t worry — the video tutorial above can walk you through the exact same steps visually.
