Scheme-it allows you to share your project drawing with others through an exported image or through a public web-link. Now, it also offers the latest reference designs from the different manufacturers in the "Design Starters" category of the left side-bar.
The "Export" button, located inside the "Main" application tab, allows you to export your current project as an image (png, svg) or document (pdf) file. This is useful if you want to include a picture of your project in reports, forum postings, blog posting, etc.
The "Share" button, located inside the "Main" application tab, allows you to create and email a public web-link of your project. Viewing this web-link does not require registration or special permission so beware that anyone can view your project if this link is shared. Make sure to set the project visibility to "Public" in order for it to be viewed.
