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
