File menu > Open
Keyboard > Ctrl+O
Open loads a scene file (MAX file) or VIZ Render file (DRF File) from an Open File dialog. You can also choose a previously opened file and use command-line options.
The MAX file type is a complete scene file.
A DRF file is a scene file from VIZ Render, a rendering tool included with AutoCAD Architecture (formerly Autodesk Architectural Desktop). The DRF file type is similar to MAX files from previous versions of Autodesk VIZ.
If the file you're loading was created using plug-ins that are not installed, a dialog lists them. You can still load the file, but any entities in the scene that were created by the missing plug-ins are replaced with stand-ins; non-rendering boxes or placeholder modifiers. You can safely delete these from the scene, unless you are sharing the scene with a user who has the plug-ins installed.
If the file you are loading contains bitmaps that cannot be located, a Missing External Files dialog appears. This dialog lets you browse for the missing maps, or continue opening the file without loading them.
When Respect System Units In Files is turned on in the System Unit Scale group of the System Unit Setup dialog, loaded files that have a different scene unit scale display a File Load: Units Mismatch dialog. This dialog lets you rescale the loaded scene to the current scene unit scale, or change the current scene unit scale to match the one in the loaded file. No conversion is done when loading files created in Autodesk VIZ 1.x.
-
If you choose to match the units in the loaded file, the System Unit Scale setting in the System Unit Setup dialog is changed to the setting in the scene file.
For example, if the current system unit scale is set to 1 unit = 1 inch, and the incoming file was set to 1 unit = 1 foot, a sphere with a radius of 100 feet remains 100 feet.
-
If you rescale the file objects, the objects are scaled as if they had been created using the current scene unit scale.
For example, if the current system unit scale is set to 1 unit = 1 inch, and the incoming file was set to 1 unit = 1 foot, a sphere with a radius of 100 feet becomes 1200 inches in radius (assuming the unit display is set to generic units).
If Respect System Units In Files is off (which is not recommended), Autodesk VIZ disregards the units chosen in the loaded scene file.
For example, a 100-unit radius sphere that was created in a 1 unit = 1 foot scene becomes a 100-inch sphere in a 1 unit = 1 inch scene.
To reopen a previously opened file:
-
From the bottom of the File menu, choose the file name.
You set the number of files listed by changing the Recent Files In File Menu field on the Files panel of the Customize > Preferences dialog.
The Open File dialog has standard Windows file open controls. At the right, the Thumbnail area shows a preview of the scene whose file name is highlighted in the list on the left.
Tip: You can resize the dialog by dragging an edge or a corner.
Clicking the plus button appends a sequence number to the file name you entered, or increments the sequence number if the
name already has one, and then opens the file of that name, if it is present.
For example, if you have highlighted a file named test00.max, clicking the plus button changes the name to test01.max and then opens test01.max.
When opening a scene created in an earlier version of Autodesk VIZ, you will see an Obsolete File dialog.
If you resave the scene, you will overwrite the file. You can still edit it using Autodesk VIZ, but you will no longer be able to edit it in earlier versions of the software.
Don't display this message—When turned on, you will not see the Obsolete File dialog. The dialog is also controlled by the Display Obsolete File Message switch on the Customize > Preferences > Files panel.
Note: If you still need to open the scene using an earlier version of Autodesk VIZ, use File > Save As and save the file using a different name. Then you will be able to open the orginal file with the earlier version.
