Some competitor software products to QCAD include ActCAD Software, ZWCAD, and Introduction to Versacad MacIntosh (Disc Included) Foster, Steven R. Software pricing starts at 39.92/one-time/user. QCAD is architectural CAD software, and includes features such as 2d drawing, architectural symbol library, and drafting. The QCAD software suite is Windows and Mac software.CAD model retrieval based on functional semantics is more significant than content-based 3D model retrieval during the mechanical conceptual design phase. The software is well supported by training and. It offers professional CAD tools for designing windows and doors in the 3D view, roof and floor plans and also customized stairs. Arcon Evo is not free software for architecture but can be said to be one of the best one in terms of features that it offers.On the basis of AAG, the functional semantics of CAD models are annotated semi-automatically by matching CAD models that contain the partial features of which functional semantics have been annotated manually, thereby constructing CAD Model Repository that supports model retrieval based on functional semantics. In this method, the geometry and topology data are extracted from STEP models. Secondly, an approach to represent CAD models as attributed adjacency graphs(AAG) is proposed. Firstly, the CAD model functional semantic ontology is constructed to formally represent the functional semantics of CAD models and describe the mechanical conceptual design space comprehensively and consistently. Therefore, a functional semantic-based CAD model annotation and retrieval method is proposed to support mechanical conceptual design and design reuse, inspire designer creativity through existing CAD models, shorten design cycle, and reduce costs.The tool comes with 2D drawing features such as a snap tool, dimensioning, and annotations. LibreCAD is an open source CAD tool that supports Mac, Windows, and Linux operating systems. The proposed research addresses actual needs and presents a new way to acquire CAD models in the mechanical conceptual design phase.4. A case demonstrates that FSMARS can successfully botain multiple potential CAD models that conform to the desired function. Finally, a prototype system, called Functional Semantic-based CAD Model Annotation and Retrieval System(FSMARS), is implemented.
Architectural Cad Versacad Software Products ToThe ROCK- CAD system has been utilized in modelling spatial distribution of rock types and fracturing structures in TVO's site characterization. The specially developed features are the application of the boundary representation modelling method, parametric object generation language and the discipline approach. The ROCK- CAD system provides, among other things, varying graphical vertical and horizontal intersections and perspective illustrations. It comprises also rich functionality for the particular geological modelling scheme. The system is based on the solid modelling technique. The application software has improved the assessment of the sites studied, given a new basis for the documentation of interpretation and modelling work, substituted hand-drawing and enabled digital transfer to numerical analysis. The utilization of bedrock models in site characterization, in tentative repository siting as well as in groundwater flow simulation is depicted. The study comprises the description of the modelling process, models and illustration examples. In this paper we describe the design and implementation of the TGeo Cad Interface that has been developed to enable the use of ROOT geometrical models in several CAD systems. The necessity to improve the level of communication between physicists and engineers led to the implementation of an interface between the ROOT geometrical modeler used by the virtual Monte Carlo simulation software and the CAD systems. ROOT is an object-oriented C++ framework used by physicists for storing, analyzing and simulating data produced by the high-energy physics experiments while CAD (Computer-Aided Design) software is used for mechanical design in the engineering field. Often, this collaboration is made hard by the usage of different and incompatible software. The physicists in charge of Monte Carlo Simulation of the detector need to collaborate efficiently with the engineers working at the mechanical design of the detector. (84 refs., 30 figs., 11 tabs.)TGeo Cad: an Interface between ROOT and CAD SystemsIn the simulation of High Energy Physics experiment a very high precision in the description of the detector geometry is essential to achieve the required performances. The necessity to improve the level of communication between physicists and engineers led to the implementation of an interface between the ROOT geometrical modeler used by the virtual Monte Carlo simulation software and the CAD systems.

Often, this collaboration is made hard by the usage of different and incompatible software. The physicists in charge of Monte Carlo Simulation of the detector need to collaborate efficiently with the engineers working at the mechanical design of the detector. The computer model can be handled, both telescopically and microscopically. Recently with the development of computer graphic techniques, we can display the components on the graphics terminal, better than with use of plastic model and actual plants. To achieve this goal, the ROOT geometry description is converted into STEP file format (ISO 10303), which can be imported and used by many CAD systems.Application of 3-dimensional CAD modeling system in nuclear plantsSuwa, Minoru Saito, Shunji Nobuhiro, MinoruUntil now, the preliminary work for mutual components in nuclear plant were readied by using plastic models. Publisher equivalent software for macIn addition, the data can be used for various planning works, even after starting operation of plant. The data can be used for piping design, stress analysis, shop production, testing and site construction, in all steps. Through application of this system, database for nuclear plants was completed in arrangement step. The relationship of this work to standardization efforts is outlined.Kim, Jhin Wung Shim, Jae Ku Kim, Sun Hoon Kim, Dae Hong Lee, Kyung Jin Choi, Kyu Sup Choi, In Kil Lee, Dong YongCAD systems are now widely used for the design of many engineering problems involving static, dynamic and thermal stress analyses of structures. B-rep model transfer results are discussed in some detail. Results from cycle and intersystem solid model transfer tests are presented, showing the practicality of the CAD*I proposal. They also describe the current state of the specification and processor implementations and include an example of a CAD*I neutral file. The authors summarize the CAD*I approach, addressing the structure of neutral files for solids, entities., and attributes supporting three kinds of representations: facilities for the transfer of parametric designs referencing library components and other general mechanisms. (author)Geometric data transfer between CAD systems: solid modelsKroszynski, Uri Palstroem, Bjarne Trostmann, ErikThe first phase of the ESPRIT project CAD*I resulted in a specification for the exchange of solid models as well as in some pilot implementations of processors based on this specification. ![]()
