FlexDoor Hardware

FlexDoor has 5 basic hardware component types.  Each is interchangeable with it’s own type.

FlexDoor Hardware
  1.  FlexDoor_Hinge – Hinges (currently not fully editable).
  2.  FlexDoor_Lockset – Includes the Handles & Lock Mechanism Components.
    • FlexDoor_Handle – There are two handles – one is a mirrored copy.
    • FlexDoor_LockMechanism – Anything you want to sit in between the handles.
  3.  FlexDoor_DoorJambHW– Anything you want to fit on the Frame side.

How to Change Door Handles

FlexDoor Hardware - 3DWarehouse Reload

Hardware can only be changed with Dynamic FlexDoor Hardware Components that have been created from within FlexDoor.  You can download FlexDoor Hardware Components from the 3DWarehouse or you can create your own Hardware Combinations.


To change the FlexDoor Hardware with one from the 3DWarehouse:

  1.  Double click on the FlexDoor handle until you reach the ‘Lockset’ component.  You will know you’ve reached the right place, when it reads “Lockset Customization” in the ‘Component Options’ window.
  2.  Right click on the Hardware Component ->  3D Warehouse -> Reload
  3.  Search for the tag words “FlexDoor" or "FlexTools” > Choose the desired Lockset > ‘Download’ and it will be replaced.


📌  Do Not Scale & Do Not Move the Hardware Component! – Edit its contents only.  If you accidentally move it, or it loads into the wrong location, click on it with the ‘Interact Tool’ - It will then jump right back into place.

Creating Your Own Hardware Combinations

You can change the handles within the ‘Lockset’ component to any shape and size you desire.

You can make your own combinations, for example:

  • Handles with or without a bolt assembly,
  • Different handles on each side.

You can delete or add a different ‘LockMechanism’.  And more . . .

Important First Steps

When editing a new ‘Lockset’ always begin with these 3 very important steps:

  1. Under the main menu select Window ->  Model Info ->  Components ->  Check ‘Show component axes’
  2. Make sure '# doors' is set to 1, and that the door is swinging towards you!
  3. The handle you will be editing must be the one closest to you.  It must be for a ‘left hand’ – The opposite (mirrored) ‘right hand’ handle will update itself when the editing is done.

Take Measurements

Measure and write down the LenX, LenY, LenZ boundary dimensions of the new ‘Left Handed’ handle you want to place.

📌  You may find Draw Boundingbox plugin by Thom Thom very helpful for taking measurements of amorphous handles.


If the handle is asymmetrical/ NOT round, measure and write down the distance between the handle ‘Axis of Rotation’ and the ‘Right Component Boundary’.

Replace with a new handle you created

See Video above


  1.  Double click to enter into the ‘Lockset’ component.
  2.  Select the ‘left handed’ handle (closest to you).
  3.  In the ‘Options Window’ change LenX LenY LenZ dimensions to correspond to the new Handle dimensions.
    • 📌  The current handle will deform - that’s OK!
  4.  Under ‘Axis Adjustment’ - If the new handle is
    • symmetrical on the YZ axis, or round like a knob – Choose ‘(a) centered‘ and ignore the next setting.
    • asymmetrical - Choose ‘(b) from right boundary‘ and enter the distance you measured from the right boundary.  (This setting makes sure the ‘Handle Distance’ FlexDoor setting is correct).
  5.  Right click on the Handle and choose ‘Scale Definition’.
  6.  Double click to enter into the handle.
  7.  Place the new handle EXACTLY within the new LenX LenY LenZ boundaries.
  8.  Delete the old handle.
    • 📌  The ‘Lockset’ is positioned according to its ‘Component Axis’ – Its axis must remain on the right boundary.  It’s Z position may be altered – Remember that its Z position is determined by the the ‘Handle Height’ FlexDoor setting.
    • 📌  The opposite (mirrored, right hand) handle will re-scale to the new scale only after it’s refreshed or if it moves.  To make sure – move the mirrored handle a little in any direction – it should then re-scale and jump back into place (If not… something is wrong! – undo and restart whole edit procedure).
  9.  Make sure to ‘Purge Unused’ to remove any remaining definitions of the old handle.
  10.  Follow the same procedure for the Bolt component.  You may also just delete the Bolt Component.
  11.  Right click on the ‘Lockset’ component -> ‘Save As’.
  12.  Done!  You can now Swap any ‘Lockset’ components with the one you just created.


The same procedures apply to the separate FlexDoor_DoorJambHW component.  (It is visible only if ‘# doors‘ is set to 1).
