Freecad is very capable and my limited experience suggests that using the spreadsheet function is more logical than Rhino and Grasshopper.I have been looking at Rhino 7 recently and it can do just about anything I would need to do.On the model engineer website there is a similar sub-forum and some of them are enthusiastic about Alibre,but engineering and furniture are different worlds.https://www.model-engineer.co.uk/for...eads.asp?t=148
