Parametric 3d modeling software is essential to delivering 3d modeling experiences today

Licencing core parametric modeling technologies

Parametric CAD technologies and stable BREP kernel are core requirements in today's world for deploying useful 3d modeling/editing experiences. 
The web browse and cloud centric computing models of delivering application experiences to users is a unique opportunity. The browser is truly cross platform and traditional desktop programs are rapidly being replaced with web apps that are always up to date and simpler for user adoption. 

Today we provide for developers an example CAD application along with a robust BREP kernel that is ready to be deployed to any modern web browser. 

History and Sketch Based 3d Modeling

We provide a robust example CAD application with a solid design philosophy. Modeling tools that are history based and parametric allow for definition of model geometry that can be updated preserving design intent. Examples of feature dialogs and BREP application interfaces can accelerate developing a specialized CAD application targeting today's latest web browsers.

JSON based model definition and data structures

JSON is a robust way to store and manage data using JavaScript in today's browsers. 
Feature histories and parametric sketch data are all stored in JSON making it easy to interface with your own JavaScript functionality.

Web-assembly BREP engine 

Performance of JavaScript has increased over the years but still can not provide speed needed for performing the complex math and optimization of surface geometry. We provide options for both API/binary licencing of our BREP engine and options to provide the source for customization by your developers.

2D Constraint solver 

2d sketcher using a completely JavaScript based constraint solver allows for geometry to be created and consumed for extrude, loft, revolve operations, ect. 

Example of both purely 2d constraint solver and 3d embedded 2d constraint solver provided.

Open Source

JSketcher is open source and available on github under the AGPL-3.0 licence. This licence is suitable for academic use but requires that if the code is altered in any way the full source code of the application is to be exposed and shared under the same licence. 

"The GNU Affero General Public License is a modified version of the ordinary GNU GPL version 3. It has one added requirement: if you run a modified program on a server and let other users communicate with it there, your server must also allow them to download the source code corresponding to the modified version running there."
