Import Revit FBX file with correct scale

Anonymous — Mon, 25 Jan 2021 22:41:12 GMT

Hi all,

I have tried numerous things that I have found on the internet re importing a Revit FBX so that the scale is 1:1.

I use 3ds Max 2019 and Revit 2019

These were the two methods I have tried with no success.

This workflows is getting FBX models into max at the correct scale WITHOUT any scaling on the geometryJ

(I work in mm as my base System Units)

Go to “Customise/Units Setup.
1. Change the system Unit scale to 1 Unit = 304.8 (millimetres).... Uncheck “respect system units in files”

File/Import/ FBX File
1. Under presets, select ‘autodesk media and entertainment’.
2. Basically turn off all settings (animation, cameras, lights)
3. *** Under units (turn off ‘automatic’, set File units converted to: “FEET”. Scale factor should automatically change to ‘1.0’.
4. Click “ok”. FBX file will import.
5. Save the file

Reset Max
1. Go to “Customise/Units Setup.
2. Change t the system Unit scale to 1 Unit = 1.0 (millimetres).... Check “respect system units in files”

Go to “File/Import/Merge”
1. Select the file you saved on step 2.
2. Simply click ok and “hey presto”.

And this method

This workflows is getting FBX models into max at the correct scale WITHOUT any scaling on the geometry.
(I work in mm as my base System Units)

1. Set System Units to mm with Unit Factor @ 1 Unit = 304.8 (feet) and respect system units scale Enabled.
2. FBX Import settings, turn off "automatic" in Units tab and select "Feet" in the pull down to force Scale factor of 1.0.
3. Import and save
4. Reset Max
5. Units back to normal (set System Units to mm with Unit Factor @ 1 Unit = 1 and respect system units scale Enabled).
6. Merge in previously saved model.
7.

= Model at right size with no scaling of the geometry/mesh.

Both of these were found here...

So far I have not been able to get both of these to work. If it helps a 1400mm wide window in Revit when imported into max becomes 13654mm in width.

Any help would be appreciated.

Thanks
