OpenSCAD.net is a partial port of OpenSCAD for the web. Powered by OpenJsCad, it uses the familiar OpenSCAD syntax to allow many OpenSCAD models to be rendered, and saved as STL, via the browser.
The layout and menu options have been made as similar to the desktop version of OpenSCAD to aid quick adoption.
Paste or type an OpenSCAD script into the editor and hit F4 (or select "Reload and Compile" from the Design menu). The model should render in the panel to the right. Any error messages should appear in the log panel at the bottom, or in the browser console.
So that scripts can utilise the "use" and "include" directives, the application can connect to a Dropbox account in order to import library files stored there. Authorising access for the app will create a dedicated, sandboxed, folder in your Dropbox space. Folders and files stored here can be referenced via "use" and "include" statements. Scripts can also be saved to the Dropbox space, via the Save option.
Several features are either not yet implemented or can/will not be implemented. For this reason many of the original OpenSCAD examples, which are available through the File/Examples menu, will not work. These are marked as such with a strikethrough.
