Description

CADProps serves as an online CAD viewer and measurement platform designed for engineers, manufacturing personnel, designers, and others who need to examine parts without the necessity of installing traditional desktop CAD applications. It is capable of opening various supported file formats, including STEP, IGES, STL, OBJ, 3MF, and DWG/DXF, as well as certain native CAD files, with functionalities that depend on the specific format and geometry involved. Users have the ability to scrutinize assemblies, measure dimensions and geometrical features, calculate surface area and volume, and estimate mass by selecting a material density. Additionally, users can compare different models, process multiple files in batches, and export relevant property data. While basic viewing and measuring functions do not require an account, signing in is necessary for converting files, saving them across devices, and generating shareable links. The platform also accommodates temporary guest access and enables collaborative model reviews, enhancing the overall user experience. Overall, CADProps provides a versatile solution for users seeking efficient ways to interact with CAD files online.

Created with a focus on modularity, extensibility, and portability, QCAD is particularly noted for its user-friendly interface. This makes it an accessible yet robust 2D CAD solution for anyone, regardless of prior CAD experience. Users can quickly engage with QCAD to construct and modify elements such as points, lines, arcs, circles, ellipses, splines, polylines, text, dimensions, hatches, fills, and raster images. The application includes a highly capable ECMAScript (JavaScript) scripting interface, allowing for advanced functionality, along with various effective entity selection tools that enhance the drafting process. Overall, QCAD stands out as an excellent choice for both novices and experienced users looking to create detailed 2D designs.
