@rubydesign super big welcome! i've had thoughts about a special 'vase' website for many years. it seems very natural to use JSCAD to create all kinds of vases. i think that others have created vases of certain kinds as well. here's a few of my thoughts... allow the user to create and adjust the outline of the vase allow the user to twist a shape as well allow the user to specify the internal shape as well allow the user to add pre-configured sections to the vase as well, e.g. wine glass stem
