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. 693
Fundamentals. Two-Dimensional Design 694 Note that since the drawings in the DXF and DWG formats are not parametric, those remain nonparametric in T-FLEX. Just like when exporting, the old data exchange mechanism can be used when importing T-FLEX CAD version 8.0 and earlier data. For this, set the “Use Version 8 Algorithm” flag. Once this flag is set, the option “Automatic area search” becomes inaccessible, while the group of options activates that pertains to the old mechanism: Create nodes: Free, On Construction Lines. This group of options allows selecting the method of creating nodes in an imported drawing: as free nodes or as intersection points of additionally created horizontal and vertical lines. IGES (*.igs, *.iges) Format When importing IGES format, you need to define the following parameters: Sew faces into solid with precision. This option allows sewing bodies from surfaces contained in the imported model, with the specified accuracy. Import Curves. When this parameter is disabled, only solid bodies and surfaces are imported. With the flag enabled, the “wire” objects contained in the source file are also imported. When imported, such objects are converted to 3D paths. The imported model gets appended to the current T-FLEX CAD document. If the source IGES model is an assembly (a set of named objects), then each object will be imported in T-FLEX CAD as a separate operation under its own name. STEP (*.stp, *.step) Format If STEP was selected as the source format, then the STEP converter dialog will be displayed upon selecting the file to import, similar to that used when exporting to STEP. The [Parameters] button calls the import properties dialog: Import geometrical entities only. This option allows selecting the model import mode: either as a set of separate bodies or as an assembly. By default this option is off. In this case, when the model is imported, the assembly structure will be created. The names of Bodies and fragments are copied from the source file. To store fragments and the assembly itself on the disk, new documents are created that contain assembly elements. Once the import completes, the created an assembly file will be opened in the T-FLEX CAD window. Meanwhile, if the flag is set, the import will result in a model consisting of a set of bodies, that is inserted into the current T-FLEX CAD document. Import curves. If this parameter is turned off, only solid bodies and surfaces are imported. When the flag is on, “wire” objects included into the source file will be imported as well. While being imported, these objects are transformed into 3D paths. Use Assembly Navigator. When setting this option, the user gets access to additional model import capabilities. The model conversion will begin with opening the assembly navigator window. This window will display the model tree. The user can, if necessary, select just some of the model bodies for importing.
