Exporting and Importing Documents model with the original (not exported) model. For example, suppose, the user created a drawing based on an External model, and then wants to regenerate it (as, for instance, because of some changes introduced to the original model, that need to appear on the drawing); in such a situation, the result will be more stable and predictable if the External model was created without use of the extra topology removal functionality. Rhino Model (*.3dm) Export options for this format specify types of T-FLEX CAD elements for exporting to Rhino model: Solids and Surfaces. When this flag is set, all visible solid and sheet bodies will be exported. 3D Profiles. This flag enables 3D profiles for exporting as Rhino curves. If flag “Closed 3D Profiles as Sheet Bodies” is set, Rhino surfaces will be generated instead of curves-bounds for the closed 3D Profiles. 3D Paths. When this flag is set, 3D Paths will be exported as Rhino curves. Visible only. This option controls 3D Profiles and 3D Paths to be exported. When this flag is on only visible objects will be exported. Solid and sheet bodies are not affected. STEP (*.stp, *.step) Format If STEP export format was selected, the “STEP converter” dialog appears after entering the file name. This window will display all system actions during model conversion. Once launched, the log pane of the dialog displays information about the file being exported, and an invitation to start the conversion by clicking the [Start] button. After the conversion begins, messages are output into the log pane about the model alteration activities. The fields “Converted bodies:” and “Excluded bodies (errors):” display, respectively, the number of successfully exported model bodies and those skipped due to conversion errors. The skipped bodies do not contribute to the resulting file. The progress bar located at the bottom of the window follows on the overall model conversion process and the process of converting model bodies. To complete a STEP converter dialog session, click [OK] button. Clicking the [Cancel] button terminates the export process without creating the file. 689
Fundamentals. Two-Dimensional Design 690 Before starting the conversion, you can additionally specify the process options. The button [Parameters] brings up the export parameters setup window: Simplify Model (recommended). Simplifies model geometry (for example, by merging edges and surfaces). Convert all non-analytic surfaces to splines. Setting this option forces conversion of all non-analytical surfaces into B-spline surfaces. This might improve the resulting export in some systems, as, for example, in CATIA and SolidWorks, but increases the size of the resulting file. Disable quick conversion. Setting this option helps more accurate representation of edge geometry. This might improve the resulting export to other systems, but makes the conversion process longer. Export all bodies as sheet bodies. Setting this option forces all bodies to be exported as surfaces. This could be helpful for interoperating with surface modeling systems that do not support solid body processing. Export curves. When this parameter is set on, in addition to bodies of the model, the wire geometry will be exported as well (3D paths and 3D profiles). The next group of options defines the method of converting Periodic geometry present in the model: “Do not split”, “Split if necessary”, “Split all”. By periodic geometry, we mean various single-piece cylindrical, toroidal, spherical surfaces and their counterpart spline surfaces, as well as various periodical curves. When converting a model into the STEP format, such surfaces and curves can be broken into pieces for better export results. If the first mode is selected, periodical surfaces and curves are exported “as is”. If selecting the second mode, then only B-spline surfaces and curves will be split. Meanwhile, this would increase the conversion time and the size of the resulting file. If the third mode is used, then any encountered periodical geometry is subjected to splitting. This increases probability of correct model reading by some systems, such as CATIA and SolidWorks. The export time and file size increase in this method as well. As an example, a cylinder can be exported as a cylindrical surface with two edges - circles, or additionally with an extra edge connecting these circles. The second case is an example of splitting a periodical surface. Splitting usually occurs along the end-of-period parameter line on the surface (for a common cylinder, this would be the parameter line at 0 or 2π). The last group of options sets the mode of exporting a multiple-solid model as: Assembly with transformation (this mode is set by default). The resulting file gets the information not only about the bodies of the model being converted, but also about the assembly structure. If some body enters the model multiple times (as identical fragments or copies of the same body), then it will be saved just once in the export, with appropriate transformations defined for each copy. For example, if an assembly contains several identical bolts, then the resulting STEP file will keep one body (bolt) and several transformations for it. Assembly. Just like in the previous mode, the model being exported is converted as an assembly and is stored together with the assembly structure. However, all bodies contained in the model are exported separately. Using this mode (instead of the “assembly with transformation” mode) increases the size of
