Exporting and Importing Documents
When importing in Assembly mode the model will be imported into multiple files retaining assembly
structure. Parts and subassemblies will be stored in the newly created documents. The root assembly file will
be opened after import completion.
When importing in the mode as Bodies, the model will be imported as a set of independent external models
corresponding to separate parts of the assembly. The imported model is added to the current T-FLEX CAD
document.
Import as single operation mode will insert the resulting single body in the current document.
AutoCAD Formats
When importing AutoCAD documents into T-FLEX CAD, you need
to specify the following parameters:
Create new Document. This option directs where the result of the
import shall be placed: in the current T-FLEX CAD or in a new
document.
Convert Text to Windows coding. Setting this option converts all
imported text to Windows encoding. This flag shall be used when
importing an AutoCAD document of one of its earlier versions
running under DOS.
Convert Blocks into Fragments. This option defines method of
processing AutoCAD “block” entities. By default this flag is
cleared and blocks are converted directly into T-FLEX CAD
entities. When the flag is on, blocks will be converted into
T-FLEX CAD fragments.
Converting blocks to T-FLEX CAD fragments may
significantly slow down conversion if there are too many
blocks and/or they have multilevel hierarchy.
3D Geometry. This parameter is used when the source AutoCAD file contains 3D solid geometry:
Ignore. When selecting this parameter, 3D geometry is ignored at conversion;
Ignore 3D as 2D. In this case, at conversion 3D bodies from the source AutoCAD model are projected
onto 2D drawing, 3D geometry is absent in the resulting T-FLEX CAD file;
Import only 3D. 3D geometry of the source file is transformed into 3D geometry of the T-FLEX CAD.
The next two groups of options (“Convert Dimensions to” and “Convert Hatches to”) define the method
of converting AutoCAD elements (dimensions and hatches) into T-FLEX CAD elements. An additional flag
for hatches “Automatic area search” enables the automatic hatch tracking (by the coordinates of points
specified in AutoCAD at hatch creation - Pick points). Its use is recommended in the cases when hatch
import fails in the normal mode (when the flag is cleared).
During the import, the points of the source AutoCAD drawing are converted (wherever possible) to free 2D
nodes within T-FLEX CAD. A large number of such introduced nodes might interfere with further
manipulations over the imported drawings. This can be avoided by setting the flag:
Optimize Construction. Upon setting this option, the nodes that are closer to each other than the specified
Join Distance, will be merged in one node.
If the flag is cleared, then nodes coincidence is not tested. This helps speed up the import process, while
could significantly clutter the drawing.
