I need to draw a floor map in vaadin, just like in autocad , in a 2d view. containing scales and basic objects and shapes (rectangle , etc...) i there any add-on or tool or open source that i can use to integrate with vaadin. i have two ideas in my head: 1- openLayer Wrapper add-on , use the vector layer to draw, but it doesn't do the job. 2- DragDrop add-on but still missing lots of functionality. Is there any add-on for autocad or visio?
