DWG Files The DWG file is the primary, native file format of drawing files created by AutoCAD, Autodesk Architectural Desktop, and Autodesk Mechanical Desktop®. It is a binary format used for importing and exporting on page 7206 AutoCAD drawing files. You can also use the File Link Manager on page 6987 to create a live link between a drawing file that can be open in AutoCAD and 3ds Max. Changes that are made to the drawing can automatically be updated in 3ds Max without having to reload scenes or re-import drawings. DXF Files DXF files are used to import and export objects to and from AutoCAD (and other programs that support this file format). Keep the following in mind when you are creating your DXF geometry, and when you are deciding whether to convert by layer, color, or entity: ■ With AutoCAD Release 12, if you are using the AutoCAD Advanced Modeling Extension (AME), use the SOLMESH command on your AME models prior to saving the .dxf file. ■ After importing a DXF file, you might want to divide the resulting 3ds Max file into smaller objects. Entities that are frozen or turned off are ignored. The successful unification of face normals depends on the welding of coincident vertices. Sometimes, depending upon the precision of the model as it was created in AutoCAD, the vertices may not be close enough to be considered "coincident." They will not be welded, and the faces will not be properly unified. In this case, increase the Weld Threshold value in the Import DXF File dialog. Converting by layer can result in objects consisting of many elements on page 7962. In certain cases, some of these elements may have all of their face normals flipped the wrong way. You can detect this in the software by turning off Backface Cull in the Display panel, or by rendering the objects. Use the Normal modifier on page 1581 to correct this. If you do not want to flip normals, you can either use 2-sided materials, or turn on the Render Setup dialog > Force 2-Sided option on page 6128. 7958 | Glossary

DWG Files

The DWG file is the primary, native file format of drawing files created by

AutoCAD, Autodesk Architectural Desktop, and Autodesk Mechanical

Desktop

. It is a binary format used for importing and

exporting

on page 7206

AutoCAD drawing files.

You can also use the

File Link Manager

on page 6987 to create a live link between

a drawing file that can be open in AutoCAD and 3ds Max. Changes that are

made to the drawing can automatically be updated in 3ds Max without having

to reload scenes or re-import drawings.

DXF Files

DXF files are used to import and export objects to and from AutoCAD (and

other programs that support this file format).

Keep the following in mind when you are creating your DXF geometry, and

when you are deciding whether to convert by layer, color, or entity:

■

With AutoCAD Release 12, if you are using the AutoCAD Advanced

Modeling Extension (AME), use the SOLMESH command on your AME

models prior to saving the

.dxf

file.

■

After importing a DXF file, you might want to divide the resulting 3ds

Max file into smaller objects.

Entities that are frozen or turned off are ignored.

The successful unification of face normals depends on the welding of

coincident vertices. Sometimes, depending upon the precision of the model

as it was created in AutoCAD, the vertices may not be close enough to be

considered "coincident." They will not be welded, and the faces will not be

properly unified. In this case, increase the Weld Threshold value in the Import

DXF File dialog.

Converting by layer can result in objects consisting of many

elements

on page

7962. In certain cases, some of these elements may have all of their face normals

flipped the wrong way. You can detect this in the software by turning off

Backface Cull in the Display panel, or by rendering the objects. Use the

Normal

modifier

on page 1581 to correct this.

If you do not want to flip normals, you can either use 2-sided materials, or

turn on the Render Setup dialog >

Force 2-Sided option

on page 6128.
