The lessons guide the user from constructing basic shapes to building intelligent solid models, assemblies and creating multi-view drawings. This book also covers some of the more advanced features of SOLIDWORKS including how to use the SOLIDWORKS Design Library, basic motion analysis, collision detection and analysis with SimulationXpress. The exercises in this book cover the performance tasks that are included on the Certified SOLIDWORKS Associate (CSWA) Examination. If properly used, parametric CAD enables the addition of design semantics to the model, which translates into the rapid alteration of existing models by simply editing the values of some parameters. Current parametric CAD is dominated by the history-driven approach, where a record of how the model isParametric Modeling with SOLIDWORKS contains a series of sixteen tutorial style lessons designed to introduce SOLIDWORKS, solid modeling and parametric modeling techniques and concepts. This book introduces SOLIDWORKS on a step-by-step basis starting with constructing basic shapes all the way through to the creation of assembly drawings and motion analysis.
Parametric Modeling Cad Software Design ToolAs a result of animation, a standard AVI-file can be created.Parametric modeling is a computer aided design (CAD) software design tool that saves timeit eliminates the need for a design engineer to constantly redraw a design every time one of the design’s dimensions change. It requires a relatively steep learning curve and modeling effort upfront for the designer, and the solid models created suffer from model interoperability issues that is, a CAD model created in software A cannot be understood or imported to software B with features and dimensions due to the nature of the. In general, parametric CAD tools lack ease of use, speed, and modeling flexibility.Formally, in T-FLEX CAD model there is no difference between a part drawing and an assembly drawing, a 3D part and 3D assembly. A fragment is an ordinary T-FLEX CAD 2D drawing (3D model), created by users themselves. A 2D drawing (3D model), which is inserted into an assembly in T-FLEX CAD, is called a fragment. Any 2D drawing (3D model) in T-FLEX CAD can be inserted into another 2D drawing (3D model), forming assembly 2D drawings (3D models). Fl studio combine audio clipsAll T-FLEX CAD parameterization mechanisms work at any depth of assembly insertion.In the first Part of the paper we described that any parameter in T-FLEX CAD can be defined by a variable. An assembly can comprise subassemblies subassemblies – include subassemblies of the next level, etc. An assembly can be inserted at any depth. It generates significant flexibility working with parametric elements. ![]() To simplify capability demonstration, videos use ready library elements nevertheless, please bear in mind that the demonstrated capabilities are true for any parametric models that users can create themselves.18. Any user will be able to change the supplied library elements or create one’s own library of parametric elements without employing any programming tools or other special tools. All library elements are essentially usual parametric drawings in T-FLEX CAD that were simply created by members of Top Systems team. All library elements are supplied in 2D as well as 3D versions. Unique capabilities for creating “smart” parametric elements and “smart” assemblies and many other interesting things about parameterization.Numerous libraries of standard parametric elements are supplied free-of-charge with T-FLEX CAD system: bolts, screws, nuts, washers, rivets, pins, bearings, flanges, etc. Differences between distinct parameterization and use of “configurations” Bill of materials (BOM) data (description, part number) also are the same. Obviously, in this case, values of the controlling parameters (variables) for different views are the same. Apart from selecting the view for insertion, you can also define values of external variables that define the standard size and variation of a library element in the assembly. Inserting into an assembly, it suffice to specify the view you wish to insert, and the system will display only the specified view in the assembly. There is no need to create “configurations” or “variations” in advance – parametric fragment recalculation happens when a fragment is inserted into an assembly with particular parameters. T-FLEX CAD enables using the same parametric fragments in different assemblies with different parameter values, without changing the initial fragment. Inserting the second bolt, on the contrary, the assembly image overlaps the bolt image, removing the invisible lines.19. Inserting the first bolt, its image overlaps an image of the parts with holes. The next example also is a good demonstration of T-FLEX CAD capability to automatically remove invisible lines in assemblies in 2D design. Using T-FLEX CAD it is possible to link fragment variables with assembly variables at any moment, which is further demonstrated by the example.Extended Fragment Parameterization (Adaptive Fragments)T-FLEX CAD has a powerful mechanism for creating adaptive fragments. Changing assembly parameters (hole parameters) results in changing parameter-dependent fragments (bolts) in accordance with the inserted links of parameters, while fragments inserted without links do not change. The example below specially shows that the same fragment (bolt) can be inserted into an assembly, with constant values of its parameters as well as with defining dependencies of the inserted fragment parameters on assembly model parameters (hole parameters). Assembly parameterization enables T-FLEX CAD users to automatically form a set of detailed drawings and 3D models according to assembly parameters. When such an adaptive fragment is created, design of any “lug” variants in new parts comes to creating a “lug” profile and inserting the adaptive fragment.29. Then the example shows how the just created adaptive fragment can be used to draw a “lug” with different geometry designing another part. The next example demonstrates how one can easily create an adaptive fragment such as “lug” indicating the fragment geometry for selection when inserting into another model. T-FLEX CAD creates user-specific adaptive fragments, an analog of user defined feature (UDF), expanding capabilities of 3D modeling and increasing productivity of designer efforts. ![]() One hole is also automatically removed on the drawing and the whole execution of the drawing is automatically rebuilt.32. The drawing is then changed in accordance with the new assembly parameters. After this, it is possible to get a new set of fully executed detailed drawings through the example of the same body. Upon recalculating the assembly, the 2D and 3D assemblies are changed, the assembly structure is changed, and the BOM is changed automatically in accordance with the new structure (1 screw and 1 bush instead of two). Then we measure the length of the part fixed in the conductor. You get a completed project of the changed assembly construction and parts. With the second method a detailed drawing is prepared, an original fragment does not change and assembly (project) files are copied, assembly parameters are applied to them and saved in a separate folder. In the second method files of parts (fragments) can be saved automatically when assembly is saved after its geometric parameters were changed. The earlier example with the conductor assembly demonstrated how applying the first method it is possible to get a set of detailed drawings and 3D models in manual mode, when each drawing must be opened through detailing function. After the assembly is created and saved, all fragments comprising the tower are copied in a separate folder with new names and are saved with parameters conforming to the assembly. The “auto-save” option is set for the fragment – angle. For instance, if this technique is used for work with metal structures, parts can be updated in the assembly context or separately modeling holes for fasteners or grooves for welding seams.The example demonstrates creating a parametric assembly metal structure – a tower from a single adaptive fragment – angle. This method allows to automatically getting a completed project of a new assembly unit with changed parameters including all assembly parts.34. All other angles are also recalculated parametrically but they do not have holes. The updated angle, which also changes parametrically, has a hole. Further editing of the assembly parameters enables changing the assembly and all its parts. We see that only this angle has changed (a hole appears), all other angles remain without holes.
