DXF/DWG and DWF export options

DXF/DWG export:

Choose from three exported file formats: DXF as plain text, DXF as a binary encoding, and DWG.

One of the main differences between these formats is file size. Although individual files can vary, an uncompressed text DXF file is generally larger than an uncompressed DWG file. However, the file size can be significantly reduced by using a compression utility. A compressed text DXF file is normally smaller than a compressed DWG file. Binary DXF file sizes generally fall between the two for both compressed and uncompressed files.

In addition to file size, consider the formats that other applications can support. Before exporting to binary DXF or to DWG, ensure that the receiving party’s software can read those formats. Since binary and text DXF both use the same .dxf extension, if the DXF file cannot be opened, it may be mistakenly considered corrupted. When in doubt, export as text DXF, which is universally supported.

Certain versions of AutoCAD have issues when reading some DXF files, such as losing links to images, so DWG is usually a safer choice in that situation.

DXB is a simpler file format used by some third-party applications that do not support the full DXF or DWG file format. It is not the same as binary DXF; do not use .dxb as the extension for binary DXF files. The Vectorworks program does not support DXB.

DWF export:

Choose from five file formats: DWF as plain text, DWF as a regular or compressed binary encoding, 3D DWF, or DWFx.

The options on this list change depending on the contents of the file being exported, on which export Version is selected.

Select the items to export from the list. By default, the selected layers are exported to a single file; to export multiple files instead, select Export layers as separate files.

The design layer options differ depending on whether Export classes as DXF/DWG/DWF layers or Export layers as DXF/DWG/DWF layers is selected on the Classes/Layers pane. Additionally, you have the option to Export as flattened 2D graphics (Objects pane) when you export design layers. For Selected Design Layers, select the layers from the list below.

Vectorworks takes into consideration several factors to determine which layers are visible for the purpose of the export: whether the design layers are set to be visible or gray, which design layer is active (this layer is always considered visible), and the Layer Options setting (Active Only results in only the active layer being exported, regardless of the visibility settings of other layers). All Visible Design Layers exports only the layers that meet the visibility criteria. All Design Layers and Selected Design Layers export invisible layers, which can be made visible later in the exported file format. Review the layer selection for export and the visibilities in the list below; if you need to change the design layers' visibility, cancel the export and adjust the visibility in the file.

If a sheet layers option is selected, the included sheet layers are exported as paper space layouts; also, design layers used in viewports are exported to model space. While multiple sheet layers can be exported to the same file, note that unrelated sheet layers usually should be exported to different files. For Selected Sheet Layers, select the sheet layers from the list below.

If a saved views option is selected, saved views are each exported as separate files. For Selected Saved Views, select the views from the list below.

Depending on the Export setting, all the design layers, sheet layers, or saved views in the file display in a list browser. A check mark in the Select column indicates which items are included for export. 

When Export is set to a Selected option, click in the Select column to place a check mark beside the items to export. When Export is not set to a Selected option, you can scroll the list and click a column header to sort the list, but you cannot change the selection.

For design layers, a Visibility column displays whether each layer is currently visible for the purposes of the export. Vectorworks takes into consideration several factors to determine which layers are visible for the purpose of the export: whether the design layers are set to be visible or gray, which design layer is active (this layer is always considered visible), and the Layer Options setting (Active Only results in only the active layer being exported, regardless of the visibility settings of other layers). All Visible Design Layers exports only the layers that meet the visibility criteria. All Design Layers and Selected Design Layers export invisible layers, which can be made visible later in the exported file format. If you need to change layer visibilities, cancel the export and make the changes in the file. 

Opens the DXF/DWG Export Layer Mapping dialog box to create, edit, and rename mapping sets (see Mapping layer and class names)

DXF/DWG export:

Exports invisible classes to invisible DXF/DWG layers. If the option is selected, objects that are in invisible classes in the Vectorworks file are exported, and can be seen by making the DXF/DWG layer visible. This is the recommended option. However, if invisible classes contain private information or if the size of the exported file needs to be reduced, deselect this option to remove them from export. If classes are visible in a design layer but invisible in a sheet layer, this option prevents them from being exported.

If invisible classes are exported as DXF layers, objects on invisible Vectorworks layers are not exported. To export these items, first make the layers visible, and then select the appropriate Export option.

DWF export:

This option is grayed; only visible graphics can be exported to DWF.

Export 2D fills

Select this option to export solid fills as wipeouts (DXF/DWG versions 2000 and later) or solid hatches (DXF/DWG version 14 and higher). You can control the export of tile and image fills separately.

Export tile fills

Select this option to export tile fills as clipped blocks; otherwise they are exported as solid fills or wipeouts (depending on the tile fill background color).

Export image fills

Select this option to export image fills as clipped images; otherwise they export as solid fills. This option is only enabled for DXF/DWG versions 14 or higher.

Export images and image files

Select this option to export image objects and image files (for example, PDFs and logos). This option is only enabled for DXF/DWG versions 14 or higher.

Export hatches

Select this option to export Vectorworks hatches as bhatches; no hatch pattern files are created unless Export hatch pattern files is also selected.

Export hatch pattern files

If Export hatches is enabled, select this option to create additional hatch pattern (.pat) files in a specified folder. A Vectorworks hatch with multiple levels and colors generates multiple hatch pattern definitions. See Preparing to export for more information on the conversion.

The hatch pattern files, and the DXF/DWG exported file and any support files, such as .jpg images, are placed in this folder. AutoCAD requires the hatch pattern files to retain the hatch associativity and to add hatches to additional objects with the same hatch pattern. When Export hatch pattern files is disabled, AutoCAD displays the hatch but cannot edit it.

This option is grayed during DWF export.

Export hatches and 2D fills into separate DXF/DWG layers

Select this option to export all of the fills, patterns, gradients, and hatches within a class (or design layer, if layers are exported to DXF/DWG/DWF layers) to a separate DXF/DWG/DWF layer. The DXF/DWG/DWF layers are named after the original class or layer that contains the object to which the fill, pattern, gradient, or hatch is applied. For example, if the Vectorworks file has an object on the “Hardscape” layer with a hatch applied to it, the export file will have a layer called “Hardscape_Hatch.”

Line Types

Export complex line types as blocks

Select this option to export complex Vectorworks line types as anonymous blocks, which preserves the exact appearance of the drawing. If the option is disabled, complex line types export as true line types, and additional graphic information is compiled into a shape file (.shx).

Line Weights and Colors

Use true colors

Exports line colors with the Vectorworks RGB values, and converts line weights to the closest possible DXF/DWG/DWF weight value. Named Vectorworks colors export as named DXF/DWG/DWF true colors.

For DXF/DWG version 2004 and later, select this option only if the exported file will not be used with a .ctb file for plotting or printing in AutoCAD. If the exported file is intended to be used with a .ctb file later on, select Use DXF/DWG indexed colors instead.

Use DXF/DWG indexed colors

Exports line colors with DXF/DWG/DWF indexed color values, and converts line weights to the closest possible DXF/DWG/DWF weight value.

Unlike Use true colors, this option allows you to use the exported file with a .ctb file for plotting or printing in AutoCAD. You can either use a predefined .ctb file, or select Map line weights to colors to create a .ctb file specific to this drawing upon export.

Map line weights to colors

If Use DXF/DWG indexed colors is selected, this additional option creates a .ctb file for each exported DXF/DWG/DWF file (named after the original .vwx file) to be used during plotting or printing in AutoCAD. The AutoCAD user must put this file in the support path, as AutoCAD does not read the .ctb file when it is simply included in the same folder as the DXF/DWG/DWF file.

During the export process, a list of line thicknesses (weights) in the file displays. Specify the color to map to each of these line thicknesses. To select a different color for a selected line thickness, click the color box and select a color from the displayed options.

If Export layers as separate files (General pane) is also selected, the mapping dialog box does not display; instead, the Vectorworks program automatically maps line thickness to colors according to a predefined standard.

To avoid having a color table file for each exported file, use a single .ctb file for each unique mapping set, and delete the others. When an exported file is opened in AutoCAD, edit the page setup and choose an appropriate color table file.

When you import the file back into the Vectorworks program, use the reverse process to convert the colors back to line thickness.

Export only selected objects

Select this option to export only the objects that are currently selected in the drawing; this option is grayed if no objects are selected

Export as flattened 2D graphics

Select this option to export objects as follows:

Design layers: All of the objects from the design layer export as flattened 2D graphics.

Sheet layers: Section viewports export as groups directly in the paper space. Top/Plan viewports export as DXF viewports in the paper space, with corresponding flattened source graphics in the model space. Viewports with a view other than Top/Plan export in the paper space as blocks of lines, polys, or other primitives, depending on the current viewport rendering mode; no corresponding source graphics are provided in the model space.

This option is selected and cannot be changed if Export viewports as 2D graphics in model space (General pane) is selected.

Use data visualization and overridden attributes

Select this option to export objects within viewports with their overridden graphic attributes (fill/pen style/color and line start/end markers) from either a data visualization applied to the viewport or class overrides applied to the viewport, when possible. If this setting conflicts with other settings, the export preserves the objects’ appearance after export, even if that means losing class definitions and attributes.

This option could significantly increase the size of the resulting file, or the number of files if design layer viewports are exported as a separate file.

Preserve mapped font on export

If the file contains text that has been mapped to a different font, select this option to export the text with the replacement font; if the option is disabled, the text is exported with the original font

Preserve SIA dimension text appearance

Select this option to maintain the SIA dimension superscript formatting upon export. Dimensions are converted to non-interactive objects.

Deselect this option to change the SIA dimensions to a non-superscript dimension format.

Export solids as ACIS solids

Select this option to export most Vectorworks solids and NURBS surfaces as ACIS objects. Deselect this option to export solids as polygonal faces (if the target software package cannot read ACIS solids, for example).

Walls, roof and floor slabs, filled 3D polygons, meshes, and NURBS curves cannot be exported as ACIS solids.

This option is grayed during DWF export.

Triangulate to preserve fills

Some software packages, such as AutoCAD, are not capable of rendering exported 3D surfaces that have more than three or four vertices per face. Select this option to break up such faces into a set of triangles that can be properly rendered. The algorithm used works best on planar or nearly planar surfaces, such as the top of an extruded circle.

Even if Export solids as ACIS solids is selected, this option may be used to handle 3D objects that cannot be exported as ACIS solids.

When in doubt, select this option (this increases the exported file size and the time necessary to export it, and may result in unwanted lines in some cases).

Decompose 3D symbols and groups

Some software packages cannot handle exported groups and symbols. If a problem occurs, select Decompose 3D symbols and groups to convert symbols and groups to ungrouped objects. Do not select this option unless it is absolutely necessary.

This option is grayed during DWF export.

Export groups as anonymous blocks

Normally, Vectorworks groups are exported as named blocks, which can be opened and edited in other software packages. However, the named blocks are imported back into Vectorworks files as symbols. If this creates a problem, select Export groups as anonymous blocks, which are imported back into Vectorworks files as groups.

This option is grayed during DWF export.

Update visible out of date viewports prior to exporting

Automatically updates any visible, out-of-date viewports before exporting

Reset all plug-in objects that require a reset prior to exporting

Automatically resets plug-in objects that require an update (such as title block borders) before exporting

Recalculate worksheets prior to exporting

Automatically recalculates worksheets before exporting
