You have a complex design to create. What 3D modeling software should you use?

For quite some time now, I have observed that massive CAD models are done in CATIA 3D modelling software. CATIA has remarkable and extensive 3D modelling features revolving around surface modelling and parametric design which generally allows one to come up with detailed and more precised designs, no matter how complex or big the design is. Hence, most industries like aerospace and automotive rely on it for design purposes.

Whatever is fit for purpose!!! Industry seems to like to overcomplicate things. Find what's yours for the people you have and the skillsets they possess.

My always go to software will be Catia. Catia is an all in one tool which helps me do design and simulation simultaneously. It has great features for surface design.

Usually people use SOLIDWORKS and other softwares like this, but when it comes to industrial level usage like automotive surface modeling, aerospace design etc the CATIA and Siemens NX are used. As per my knowledge,Mercedes uses UG NX while BMW,AUDI and PORSCHE like brands uses CATIA. BTW Siemens NX has more friendly user interface than CATIA V5.

My go-to for complex designs is Dassault Systems CATIA. Whether it's parametric modeling, intricate surfaces, or detailed sheet metal, CATIA's diverse features consistently meet my exact requirements. While other software like Creo, Solidworks, and NX offer advantages, CATIA's versatility in handling complex geometries, seamless assemblies, and efficient design changes makes it my preferred choice. Solidworks, with its user-friendly interface, comes as a close second in my toolkit for intricate projects. The software choice varies from person to person, but for me, CATIA stands out in delivering precision and efficiency in complex 3D modeling tasks.

Parametric modelling is equation based modelling and we can control the whole geometry with the help of equations. I am curious if we can create an excel sheet for a specific part and just like an excel sheet when we drag it and fill the rest of the columns that will definitely create configurations. I want to see how the model is being updated after several rows. If it works?? ???????? ?????????????????? is basically used for reverse engineering the 3D scanned Files in which we have a Mesh and vertices that we use to model that specific part but for complex part we need more computational power for it. The third one is ???????????? ??????????????????, is basically the thing we mostly use. Creating 3D models with the help of Features

Most of the software is designed with advantages and specialities. About the integration, collaboration, compatibalility, simulation with proper market segment and target audiences.from the 3D Visualisation, Industrial Design, Rendering, CAD, CAD-CAM, Engineering Analysis. Every market segment have their own preferred software, from their previous technical support, annual subscription price to software ability and surrounding.

Die meisten Systeme der direkten Modellierung in der mechanischen Konstruktion wie ME10 (heute Creo Direct) sind kein ?Mainstream“ mehr. Es gab noch Space Claim, das heute das 3D Modul in Ansys ist. Ferner hat Shapr3D als Direktmodellierer begonnen und fügt gerade das parametrische Modellieren hinzu. Es macht es genauso wie SolidWorks und Onshape, die ich recht gut kenne. Die Direktmodellier-Aktionen werden im Featurebaum integriert. Direkte und parametrische Modellierung sind vereinigt. Meiner Meinung nach sollte man auf parametrische Konstruktion nicht verzichten. Diese ist Grundlage für sp?tere Automatisierungen. Bei der Modellierung organischer Fl?chen macht Parametrik keinen Sinn. Spline-Stützlinien bei Freiform kann sinnvoll sein.

For anyone working in engineering, parametric 3D modelling software will certainly be of most interest, simply because it is perfect for complex designs, components and assemblies. It also makes much more sense to use parametric software for 3D printing or CNC manufacturing rather than the other two.

Parametric Modeling is extremely powerful for defined components and assemblies that require constraining relationships to geometry, components, and sub assemblies; allowing projects to automatically reconfigure when a change is made to component(s). Meshes are great for more organic surface and non-finite geometry, which maybe more difficult to define—requiring an “artistic touch”—akin to digital clay sculpting. We are realizing increased implementation of mesh geometry in parametric projects, by utilization of Generative Design: computer generated geometry based on engineer specified geometric and performance requirements. This is the nexus of organic designs seen in meshes, but provides calculated performance in parametric designs.

Finding the best 3D modeling software for complex design depends on several factors: 1. Purpose: What are you trying to achieve (engineering, architecture, animation, etc.)? Different software suits different purposes. 2. Budget: Consider how much you are willing to spend. 3. Skill Level: Choose software that matches your expertise. 4. Project Scope: Ensure the software can handle the size and detail of your project. 5. Preferences: Pick software that fits your personal or team preferences.

In the field of architecture, the prevalent trend is the use of non-standardized designs known as "freeform." Zaha Hadid is a prominent architect associated with this style. In previous generations, architects utilized tools like CATIA, which were designed for architecture as well as automotive and aircraft design, for freeform designs. This era involved direct modeling and management of irregular shapes, not relying on parametric design. However, the current trend leans towards parametric design using tools like Rhino's Grasshopper and Revit's Dynamo. With the advent of the creative AI era, parametric design is expected to become even more powerful.

Simplicity in terms of both resources availability and software components adaptability is quite useful, bearing in mind that the resolution must be the one expected.

One thing I've found helpful is to pre determine the perameters for your model and then investigate softwares. Having experince in multiple industries with different softwares. If you were modelling a mechanical assembly you wouldn't want to use a software like Rhino because it's a lot better for surface modelling e.g. product designing or Aeronautical designing. Inventor is extremely strong if you use all their features and Excel driven modelling, even more so if you scaling up models this works really well if you have a lot of varied repeat models. First time modelling, a "lite" version of Inventor would be SolidWorks, this is a good programme to probably start on. You can always change! Never think you stuck in 1 programme!

Just keep in mind that the "best" software is subjective and varies depending on individual preferences and circumstances.

to succeed in your 3d modeling you must to : - choose the right plan to start your first sketch. - try to minimize the functions as much as possible. - make a scheduling of operations so that the modification of a dimension afterwards is feasible.

CAD Software im Dentalbereich bietet h?ufig die M?glichkeit, die vorhanden Scandaten des Modells zu spiegeln oder auf diverse Zahn-Bibliotheken zuzugreifen. Dadurch verkürzt sich die Konstruktionszeit, sowie die Komplexit?t für neue Anwender.

Para empezar es recomendable realizar un boceto con o sin las cotas, para al menos ya tener la idea en papel y poder visualizarla más rápida. Cuando los proyectos son más complejos es recomendable también realizar un plano en AutoCAD 2D. Lo bueno que tienen software como Inventor o Solidworks, que al momento de equivocarte puedes ir al boceto y editarlo. Es importante realizar el dise?o 3D de manera ordenada, para que al momento de editarlo o entregarselo a otra persona sea más fácil de utilizar.

1 Try to maintain the workbench as clean as possible. 2 Maintain the proper tree structure of the model that can be easily understandable by any other. 3 Always use shortcut keys as maximum. 4 Use of concept sketch in mind before modeling.

To optimize your 3D modeling process, start by thoroughly planning your project and organizing your workspace. Learn and utilize keyboard shortcuts and hotkeys to speed up your workflow, and make use of templates and presets when applicable. Practice efficient modeling techniques, optimize meshes to keep polygon counts low, and leverage modifiers and parametric modeling features. Manage textures and materials effectively, save your work frequently, and stay updated with the latest tools and techniques to continuously improve your skills and efficiency.

Topology becomes increasingly important the closer the product is to manufacture because poor topology is noticeable when a product is made. This does not stop many companies producing these products however because topology errors can still be hidden with highly textured material finishes. For the gold standard in topology look to vehicle manufacturers. Certain modelling practices help with topology such as always building surfaces using a patchwork of 4 sided surfaces (quads). This is especially relevant when using Solidworks. Choosing the right software to build a complex product is the most important factor in improving topology however as different CAD softwares are better at building different geometries.

Keep it simple and efficient. Proper mesh structure matters for smooth rendering and animation. Regularly save your work to avoid losing progress.

Always start with thorough planning and research to clarify project goals and requirements. Maintain good communication with clients or team members to ensure alignment throughout the process. Regularly check and optimize your models for issues such as geometry errors, non-manifold geometry, and overlapping faces. And never forget to save your work

Como impulsor de dise?o y en su momento iniciar el departamento de Dise?o en una compa?ia me vi en la mision objetiva e imparcial de elegir el software CAD para la organziacion, para ello tome en cuenta aspectos como mi expertise en software, tambien evalue el costo benefecio, soporte tecnico de los provedores, capcacidad de los equipos de computo requeridos, compatibilidad de formatos y considerar que software de dise?o utilizan tus aliados (clientes y provedores)

No matter how proficient I am in my chosen CAD package, I always start on a piece of paper with a pen. It is easy to be seduced by all the beautiful modelling and animation the modern CAD provides, that one forgets to actually solve the problem.

Experimenting different software and taking advantage of the flexibility they offer to design a structure can be interesting, the same object could be designed twice or more with a slight difference in the renderings.

Strategy is everything. And I absolutely agree with using paper first, even if it’s to make an assembly “tree” or sequence. From there you can determine what exists, what doesn’t, what can be modified or adapted. Use the 6P’s: Proper Preparation Prevents Pi*s Poor Performance. Name critical features. Volatile (hi risk of change) features at the model trees end. Consideration of using skeletal/layout modeling (top down strategy), multibodies, etc. Perhaps most important of all is eliminating model rigidity, for instance by using Delphi’s Horizontal Modeling strategy. Not intuitive, but tops in preventing errors when “I just gotta change this one thing” (and inadvertently explode a chain of parent-child relationships) ??
