In 3D modelling, customers can easily visualise the objects model derivations for detailed views or complicated building areas can be quickly created at any position. A lot of information, which was previously kept in complex additional lists, can be integrated directly into the model or linked to the model. Parametric models have component libraries, fixed or freely defined parameters in the component types (walls, ceilings, stairs, windows, doors) and can be placed with dependencies to each other. The wireframe model is often sufficient for conversion planning and collision detection, but does not provide any further information about the object beyond the pure geometry data. Software solutions such as Autodesk Revit or ArchiCAD are used for this. We distinguish between modelling as a pure wireframe model and modelling as a parametric 3D model. The entire elements "building", the technical installations and, if required, the furniture are captured "as-built" and represented in the 3D model in XYZ dimensions. The exchange is uncomplicated and the data can be read by any software.ģD modelling is the modern form of as-built documentation. The data is compact and has a small file size. 2D plans have existed for many years the plans are standardized, understandable for everyone and correspond to predefined accuracy guidelines. The number and location are defined in advance. When analysing in 2D, floor plans, detailed plans, facade views and sectional views are usually generated. We are often asked where the real added value of a 3D model is? Where exactly are the advantages or disadvantages of 2D or 3D modelling and which variant should you use in your next project? 2D modelling Ideas are developed on sketch paper, materials are assigned, rooms are furnished – and then digitally implemented. The 2D analyses of floor plans, sections and views are a familiar and firmly rooted basis for creative planning and conversion work. In architecture, we are experiencing a rather timid change. Especially in the fields of industry and automotive engineering, 3D modelling has become firmly established and is constantly developing. While in many areas people still work in 2D, others have recognised and implemented the advantages of 3D modelling long ago.
It also follows a very old and soon to be obsolete idea of closed software, something that will leave it in the dust just like iOS was left in the dust by Android (with regards to market share).Time is changing.
SolidWorks is a great package, i get it, but it is not free for businesses (like mine) and it is not open to tinkering (like we need).
but that doesn't happen so long as your proprietary software implements the standard file formats to spec. Yeah that hypothetically would be an issue. Having an open source text document change its margin from 1/2" to 3/4" is one thing, but having some open source CAD model change a mounting hole from 1/2" ID to 3/4" ID is a whole other story. Memories indeed, you should try it again, development never stopped. At the moment, it is just fluff that few people actually "need" I use Blender (Another open source mesh based CAD package, shitty for parametrics, but great for rendering and animations) for this at the moment, but that can get merged in in the future. Outputting models to DCC software for product visualization. Open source is the most important feature of ths software, it may take longer to get perfect, but once it is, no one will ever have to pay for CAD/CAM ever again.Įxchanging files with other people and other companies is common.įrom the main FreeCAD page: "Import/export to standard formats such as STEP, IGES, OBJ, DXF, SVG, STL, DAE, IFC or OFF, in addition to FreeCAD's native Fcstd file format." I think at least one of those would be sufficient for transporting files. We are also building a database of open CAM profiles and beginning to support machines one by one. As for non-open CAM machines, you presumably have the CAM package that came with it and can pull in any of the supported file formats. I am writing a Slic3r plugin now, so this should support all open source CAM systems. You need to export your models out to CAM programs. I have written many different plugins and have never had as smooth of an experience as I have working with FreeCAD. Using 3rd party plug-ins that expand the power of the core application.įreecad is the most open platform for plugins of any CAD package (SW included.). Well the FEA is at the bottom of the link, you should read to the end of that tutorial. You need to interface it with FEA software.
