We didn’t make it easy to get this dialog back…
Updated: but we did make it easier than I originally thought! Thanks Electrotoast!
Step 1. Run 3ds Max with the one of the following command line options: -df, -dfc or -dfd
You can do that by editing your shortcut or by running 3dsmax.exe from a command line.
The three options are:
- -df: gives you the dialog again so you can chose which mode you want to use
- -dfc: no dialog, runs 3ds Max in Classic mode
- -dfd: no dialog, runs 3ds Max in Design mode
Step 2. Remove the user settings
And rename or remove your user settings C:UsersYOURNAMEHEREAppDataLocalAutodesk3dsMax2016 – 64bit (where you replace YOURNAMEHERE with you Windows login name).
The next time you start 3ds Max 2016 you’ll can choose your initial 3ds Max experience again if you’ve used -df. Or you’re straight in Classic mode (with -dfc) or Design mode (with -dfd)
You can also add the following flags to the end of your Shortcut’s target:
a. Right Click your 3ds Max shortcut > go to Properties
b. Under Target: add one of the following flags AFTER the quote “C:Program FilesAutodesk3ds Max 20163dsmax.exe”
Display the dialog:
Start with Classic:
Start with Design
EXAMPLE to launch the window again: “C:Program FilesAutodesk3ds Max 20163dsmax.exe” -df
Finally, rename or remove your previous user settings: C:UsersYOURNAMEHEREAppDataLocalAutodesk3dsMax2016 – 64bit (where you replace YOURNAMEHERE with you Windows login name).
Once you have reset the defaults, remove the flag, otherwise, you will get the dialog everytime you launch.
