RapCAD is a Rapid prototyping CAD IDE for RepRap and RepStrap 3D printing machines.

Scriptability
OpenJSCAD.org allows for designs to be created programmatically using JavaScript, which provides great flexibility and precision in creating complex geometries.
Online Platform
The tool offers a web-based environment where users can access their designs without needing to install complicated software, making it convenient and accessible.
Parametric Design
Users can easily create parametric designs, which are adjustable by simply changing variables, allowing for rapid prototyping and iterative design.
Open Source
Being open-source, it encourages community contributions and allows users to modify and improve the software to fit their needs.
3D Printing Integration
OpenJSCAD.org is well-suited for producing designs that can be exported directly for 3D printing, simplifying the pipeline from concept to physical object.

Learning Curve
There is a steeper learning curve for users unfamiliar with programming, as designing requires knowledge of JavaScript.
Limited GUI
Compared to traditional CAD programs with feature-rich GUIs, OpenJSCAD lacks intuitive drag-and-drop interfaces, which can make design processes more time-consuming for some users.
Performance
For complex or large designs, the performance can be lacking as it runs in the browser, which might not handle heavy computations well.
Debugging Challenges
Debugging code-based designs can be more challenging compared to fixing visual design errors in traditional CAD software due to the text-based nature of scripting.
Customization Requirements
To achieve certain advanced functionalities, users might need to dive into customizing or extending the core functionalities, requiring deep technical skills.
