Understanding NURBS Non-Uniform Rational B-Splines (NURBS) is simply the name for the mathematics that is used to create the geometry in Alias, and in many other CAD systems. Luckily, no understanding of the math is required to become an expert Alias user. There are a few technical terms that are used for controlling the shapes we design, but they are simply learned as each tool is learned, and don't need to be understood in a mathematical way. (If you are interested however, a useful overview of NURBS modeling and mathematics is given by.) The key benefit of NURBS is that it isn't an approximation of a smooth shape.
Can you help me with just teh title covers or a scanned list of his novels tat may appear on back cover of his some of teh novels. Islamic urdu book pdf. I need authentic information. You have saved perhaps the greatest literary treasure of Pakistan, which now a days in the internet age no body want to read or understand. I need to up adte the wiki page of Mr.A Hameed ( teh prolific writer) who wrote thousands of books including his novels in digest line Naya Ufaq Naya rukh etc., but the list is incomplete.
The math calculates an accurate definition of the surface shape which is still smooth however closely the surface is examined. Why NURBS are used More important than the underlying math is understanding what unique features Alias NURBS have to offer you as a designer, compared to the other software tools you may be using:. Flexibility to create sculptural shapes. Tension to keep surfaces smooth and taut. Alignment to create smooth, invisible joins Designing with this level of attention to sculptural aesthetics is a specialized area of CAD modeling, typically used for premium products where elegance and surface quality are important factors in the product's appeal.

Manufacture from polygonal models The first step in a reverse-engineering workflow consists in transforming digitized point clouds into a polygonal model, an operation also called 'meshing'. Sophisticated data-processing techniques, including point smoothing and curvature-based sampling, can be applied to raw point clouds during the meshing phase. As a result, polygonal models tend to be more compact, more accurate, and less noisy in comparison to the raw measurements. Several industrial applications are capable of directly handling polygonal model representations. For example, polygonal models can be either directly milled, built using a 3D printer, or input into aerodynamic simulation software. PolyWorks Modeler provides t wo categories of polygon-editing tools to prepare polygonal models for these applications:. A first set of tools is designed to repair and optimize imperfectly digitized geometry.
For example, it may be necessary to interpolate new polygons over unmeasured areas to create a complete surface representation. A second set of tools offers CAD operations on polygonal models, such as extrusion, offset, fillet, and Boolean operations. Generate CAD-friendly freeform surfaces Professional CAD/CAM solutions do not typically offer 3D modeling tools for polygonal models. One common way to transfer the surface of a digitized object into CAD/CAM software consists in fitting a network of NURBS surfaces over a polygonal model built from digitized point clouds. NURBS surfaces are ideal to mathematically describe freeform surfaces, plus they are CAD/CAM friendly. PolyWorks Modeler offers an intuitive surfacing approach in which curves are first laid down on a polygonal model, and then automatically intersected to form four-sided or N-sided trimmed NURBS patches. Next, the NURBS patches are used to control the fitting of a continuous network of NURBS surfaces.
Fitted surfaces can then be exported to IGES or STEP files and directly imported into your favorite CAD/CAM application for further processing. Build solid CAD models from optimized geometric entities The solid modeling philosophy of PolyWorks Modeler consists in optimizing the extraction of geometric entities on digitized polygonal models, and then transferring these entities to your corporate feature-based solid CAD modeler to guarantee the creation of parametric, associative, and fully editable solid models. A fundamental building block in a solid modeling workflow is the parametric 2D sketch. 2D sketches consist in planar entities, such as arcs, lines, circles, and splines, defined on a plane embedded in 3D space.
In solid-modeling software, sketches are used to create solid base features by performing Extrude, Revolve, Sweep, and Loft operations. Sketches are created by:. Defining a sketch plane. Computing a sketch outline by slicing cross-sections of the digitized model or extracting its silhouette edge. Anchoring and fitting sketch entities and dimensions, guided by the sketch outline The parametric sketches are then transferred to the solid CAD modeler by using add-ins (for CATIA, NX, Creo, SolidWorks, and Inventor) or a neutral format (IGES). You can then combine the sketches and fitted NURBS surfaces, use the dimensions from fitted prismatic geometry, and design the solid model you want—all done directly in the professional CAD solution that you’re most familiar with.
The solid modeling possibilities are unlimited with PolyWorks Modeler, so let your creativity lead the way!
By playing the two-minute demo, you can judge if XNurbs is the most powerful and easiest-to-use NURBS software ever developed. XNurbs delivers unprecedented power for designing NURBS surfaces:. Unlimited capacity for solving NURBS: Its optimization algorithm can solve virtually any NURBS surface on the fly (regardless of how complex the constraints are). High-quality surfaces: Its optimization algorithm uses energy-minimization method to generate the smoothest NURBS surfaces that satisfy all the inputted constraints – this is why the surface quality generated by XNurbs is so good. Easy-to-use: it uses one simple UI for all kinds of NURBS modeling. Native CAD surfaces: XNurbs generates native CAD surfaces, i.e., trimmed NURBS surfaces, which can be directly used for any CAD modeling operations. Example: Generating a surface from 12 curve constraints (with G2 Continuity along the boundary curves).

The following and are natively supported (without use of external plugins). When opening CAD file formats not in its native.3dm file format, Rhinoceros will convert the geometry into its native format; when importing a CAD file the geometry is added to the current file. When AutoDesk AutoCAD's file format changes (see for more information), the reverse engineers the file format to allow these files to be loaded by other vendors' software. Rhinoceros' import and export modules are actually plug-ins so they can be easily updated via a service release. Rhinoceros service releases (SR) are frequent and freely downloadable. Rhinoceros 5 SR10 can import and export DWG/DXF file formats up to version 2014. Rhinoceros is also compatible with a number of graphic design based programs.
Among them is Adobe Illustrator. This method is best when working with a vector base file. Start by saving the file and when promoted save as Adobe Illustrator (.ai) from there you are able to control the vectors created in Rhinoceros and can be further enhanced in Adobe Illustrator. 3D printing Rhinoceros 3D relies on a few plug-ins that facilitate 3D printing and allows the export of the.STL and.OBJ file formats, both of which are supported by numerous 3D printers and 3D printing services.
In a leading 3D printing service provider compared the top 25 most popular 3D modelling software programs in use today. Despite Rhinoceros 3D's plug-ins for supporting 3D printing, Rhinoceros 3D only scored a 13th place in this extensive survey coming in behind industry standard 3D packages like.
