Exporting and Importing Documents Operating System. This parameter allows selecting the type of an operating system: DOS or Windows. Default is Windows; however, if the file is being exported into an older AutoCAD version running DOS, you should change the radio group setting. When using the old data exchange mechanism, you cannot select an AutoCAD version higher than 2000. Stereo Lithography (*.stl) When exporting into the “Stereo Lithography” format, the geometrical shape of the 3D model surfaces is translated by faceting surfaces into a set of triangular elements. The accuracy of the surface representation depends on the three-dimensional mesh parameters. Maximum Surface Deviation. Represents the maximum distance between the surface and the three-dimensional mesh elements. Maximum Cell Size. This is the maximum length of a mesh element side. Maximum Normal Deviation. This is the maximum angle between adjacent elements of the surface faceting. All parameter values use model units. AutoCAD 3D (*.dxf) When exporting a 3D model in AutoCAD, the same parmeters are specified as when exporting into the “Stereo Lithography” format. Besides that, you would need to additionally specify the AutoCAD version number. Raster Image (*.bmp, *.jpg, *.gif, *.tiff, *.png, *.tga) The following parameters are defined in the raster image export dialog: “File” group of parameters displays and allows to edit the name and type of the output file defined in the previous step. “Export” group of parameters defines the export image: Current View. This setting means exporting the current window image; Current Page. This setting means the current 2D page image will be exported; Rectangular Area. This setting serves to manually define a rectangular area of the 2D page, whose content will be recorded in the resulting file. There are two ways to specify the area: 1. By defining the lower-left and upper-right corner coordinates of the area (“Left Bottom” and “Right Top”). The coordinates are entered in the respective fields; 687
Fundamentals. Two-Dimensional Design 688 2. By selecting a rectangular area in the 2D window. To select an area, click the button [Select…]. The dialog window will temporarily disappear from the screen, and you will be able to specify the desired area with the cursor. To return to the dialog, click in the automenu.. An additional “Hide Constructions” flag (set by default) has an effect on exporting 2D and 3D construction elements. When this flag is set, the construction elements are not exported. Please note that the “Area to Export” parameter, as well as the fields to define a rectangular area, are available only when calling the export command from a 2D window. If calling the command from a 3D window, then the “Current View” setting is forced. Besides that, when called from a 3D window, the command dialog gains another flag – “Hide Annotation Elements”. When this flag is set, the 3D annotation elements are not exported. “Image” group of parameters serves to define parameters of the file being created: the image dimensions, resolution and background color: Width, Height. These are the width and height of the image in the resulting file. If these parameters are set, the system will force saving the image aspect ratio. Units. This parameter defines the units in which the height and width of the image are specified: “Pixels”, “Millimeters”, “Centimeters”, “Inches”. Resolution. This parameter defines the resolution of the file being created. You can additionally select the resolution units: “Pixels per Inch” or “Pixels per Centimeter”.. An info parameter “Size in Pixels” serves to assess the size of the resulting file. Background Color. This parameter defines the background color of the picture being created: “Auto” (same as the active window background), “White”, “Black”, “Other” (any color from the drop-down list at the right). Quality. This parameter is available only when exporting the “*.jpg” format. It defines the rate of compression for the file. The higher the compression quality setting, the less image loss and the larger the file size will be. Parasolid (*.xmt_txt, *.xmt_bin) Formats When exporting into the Parasolid format, you need to specify the Parasolid Release. By default, the Parasolid version number is set to the one that T-FLEX CAD system is running (the maximum number). “Export material” flag is responsible for retaining faces material displayed in “rendered view” inside exported data. Note that only “color” data is considered. Texture, transparency, density and other material parameters are not transferred. An additional parameter “Delete redundant topology” engages a special Parasolid functionality for refining the model being exported. This functionality allows in some cases to remove extra, redundant topological elements whose absence would not affect quality and accuracy of the 3D model geometry. For example, this could be “extra” edges dividing a cylindrical surface into patches. Such processing helps reducing the size of the exported file and sometimes simplifies the task of importing into other systems. When recurrently using an exported model in T-FLEX CAD, remember that the described processing alters the model itself to some extent; in particular, the alterations affect its element IDs. Problems might arise with searching for parent elements due to this effect, when attempting to keep associative relations of the External
