CAD, also known as computer aided design, is the process of using computers to create, modify, and optimize product design.
This helps facilitate the manufacturing process as it builds detailed diagrams of a product’s materials, tolerances, and dimensions which can then be used in a practical context.
A ‘clash’ is the result of two elements in your design taking up the same space. In Building Information Modeling (BIM), Clash Detection is the technique of identifying if -- and where or how -- two parts of the building (e.g., plumbing, walls, etc) are interfering with one another.
The Finite Element Method (FEM) is a method of conducting a Finite Element Analysis (FEA) of a physical phenomenon. FEM can be used for studying heat transfer, mass transport, fluid flow, electromagnetic potential, and structural integrity. It works by breaking up a model into smaller bits and, in turn, running an algorithm for strength, stretch, and other attributes.
A geometric modeling kernel is a 3D modeling component found in modeling software, such as computer-aided design (CAD).
You can think of a geometric kernel, or “solid modeling kernel,” as the core of a CAD system. Without the kernel, it would not be possible to produce the images you see on the screen.
If you’re having difficulties opening an IGES file in AutoCAD, follow these 5 simple steps:
- Select the “Insert” tab, followed by the “Import” panel
- Then select “Import.”
- Then select “IGES” (or .igs, .iges)
- You can then enter in the name of the .iges file in “File Name”, or you can find and select the one you want to import manually.
- Open the file
In order to open a stp file in AutoCAD you’ll need to follow a 3 step process; first, select the “Insert Tab” function, followed by “Import Panel”, and then find the STP file. Second, select the STP file you’d like to import into AutoCAD. Lastly, click to open the file.
When .stl files are imported into a 3D application it can result in errors such as misaligned edges, holes in the model, and floating parts which do not properly align with what the original model looked like. These errors can be avoided by using a 3D translation tool like Spatial’s 3D Interop.
The .3dxml zipped file type can be viewed using Dassault Systemes proprietary software 3D XML viewer. You can visit the developers website in order to download the 3DXML player.
You can download the free online 3dxml viewer, which is a standalone application, from their website - the 3D XML viewer is available for Windows platform only, as OSX is no longer supported. .3dxml file formats can be viewed using your web browser, both online and offline."
In computer-aided design (CAD), hybrid modelling is a method of using different modeling techniques (with different rulesets) in the same workflow.
IFC is short for International Foundation Class and files using the IFC file format are Building Information Modelling (BIM) files. However, unlike other BIM file formats, IFC files are platform neutral and can be read and edited by any BIM software.
The Jupiter Tessellation (JT) is a 3D data format which corresponds to an ISO standard. It is used for product visualization, collaboration, CAD data exchange, and for long-term data retention. It contains a combination of approximate data, boundary representation surfaces, product and manufacturing information, and metadata which is extrapolated from a native CAD system or inserted by a product data management system.
Meshing -- or mesh generation -- is the process of generating polygonal or polyhedral mesh (i.e., the shape of the polygon/polyhedral is made up of multiple edges, faces and vertices).
Meshing is often used in software-based simulation for Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD).
‘Revit’ is the name of Autodesk’s Building Information Modeling (BIM) software and its file format (rvt). Revit is a popular BIM file formatin the Architecture, Engineering, and Construction (AEC) industry for designing and constructing buildings and other structures.
Rhino, or Rhino3D, is a 3D computer graphics and computer-aided design (CAD) application software that was originally developed by Robert McNeel & Associates in 1980. It is based on the NURBS mathematical model which aims to produce mathematically precise representations of curves and freeform surfaces in computer graphics.
The SAT file extension stores three-dimensional geometry information within a standard text file format. It’s used to exchange 3D data between multiple systems and is saved in Spatial’s ACIS solid modeling format.
SAT files are used in the computer-aided design industries, as well as shipbuilding, 3D animation, computer-aided engineering, and more.
Surface Modeling is the method of showing or presenting solid objects. The process requires you to convert between different 3D modeling types, such as converting the 3D object to show procedural surfaces, validate imperfections, and apply smoothness. While more complex than Wireframe Modeling, Surface Modeling is easier to achieve than Solid Modeling.
The .catpart file extension was created by the 3D CAD manufacturing application called CATIA V5 - catpart (or “CATPart”) is used to store part models and includes 3D geometrical and structural data. These catpart files can also be combined with additional parts and info in order to create a catproduct assembly file.
A .iges file format is used to transfer two-dimensional or three-dimensional data for a design between CAD software, and can be saved as IGES or a .IGS file. This file type most commonly contains information about a model's surface - but may also house data such as the wireframe and/or solid model, as well as circuit information. Like other file types, IGES files are in ASCII format on the Initial Graphics Exchange Specification standard.
The .stl is a file extension that is usually created within a CAD environment and is designed to store information for 3D models. It is a simple collection of triangles representing the end product of the modeling process and is designed to show only surface attributes of the object without color, texture and other elements.
