There are more components, but these three are essential and common. The converter has to transfer the uploaded files into the native GMK format and other supported formats.

The solver is something that is more related to standalone CAD software packages, as it is responsible for designing parts and supports operations such as extrusion, rotation, substraction, etc. The viewer - which is our main focus in this article - is responsible for showing the user what they want. Figure 5 shows the components that are often found in GMKs. However, there are numerous GMKs that are open-source and available for implementation such as Open Cascade. GMK’s main purpose is to apply mathematical rules (mostly from linear algebra) to some data (a CAD file) so that the user can see the projection of the 3D model on a 2D screen and manipulate this data in numerous ways.Ī GMK is usually developed by a large team of software developers and mathematicians for several years and thus are challenging to be developed by a small group of people. Geometrical modeling kernels (GMK) that are normally used in CAD software packages are large software components that require high-level programming features and thus normally are dynamic-linked libraries (DLL) written in the C++ language.

Moreover, xeogl supports the STL file format but to some extent, e.g. xeogl allows opening 3D models in the GLTF file format on a webpage (see Figure 1). That automatically suggests that the solution should most likely be in JavaScript, as it is one of the few programming languages with built-in support in all major browsers and definitely the most popular out of them all.Īnd, as mentioned, there are tools ready to be used - JS libraries - that are allow rendering of geometry on the web in case no actual CAD functionality and only viewer is required.įor example, xeogl is a JS library which serves as a web 3D engine for technical visualization and can be embedded in a website. The second thing is that we want it on the web. The interface should be similar in many ways and intuitive for any user. The first thing we need to consider about how the solution should look like, is that we should be able to view CAD files just like we do that in CAD software on our PCs.

In this work, we’d like to cover the 3D viewers, explain how they work and discuss how to utilize them best.

This article can be of use for those who plan to have in a CAD viewer, or any other web-based 3D modelling plugin on their platform, or for anyone interested in how it all works. The GrabCAD users can use the search engine to find a CAD file of their interest by keywords or description, go through results by looking at rendered images of CAD models, and select the most suitable option among them for download.

It allows not only to upload or download a CAD file, but also to preview it via either prerendered images or in the embedded 3D viewer.

GrabCAD is a free online platform that allows sharing of CAD files in various formats among its 4 million users. For example, GrabCAD is a company that implemented web-based CAD viewers on their platform. There are many applications for web-based CAD viewers, but most of them are of engineering nature. Viewers in general are much simpler packages than GMKs and CAD-systems, mostly because they allow using the CAD viewing features without having the CAD design features. However, as we don’t want to bring the whole CAD system online and only want to view CAD models, we reduce the complexity of the problem enough to have already existing and working solutions. This is mainly due to absolute or partial inability of existing online approaches to perform complex computations with appropriate performance. Opening a 3D computer-aided design (CAD) model within a web-based service can be more challenging than one could think.
