MANUALCAD

After the first research and the draft model we decided to test physically at the sale 1 our toolkit with cardboard and to keep the idea of the splits which create the grid and can be a mark for the scale. Also we designed some pieces of cardboard too which have small symbols to be used as a legend and allow the architect to create his own legend. We also add curve pieces because it was one of the main issue of our toolkit ( how can we implement curves with an orthogonal grid?). 

So when we built it we tested it and we agreed that the cardboard is a good solution to have something enough strong to get stability and have an easier manipulation for blind people without being too heavy. But there was still some problems we had to solve. For example how can we fix the curves and the diagonale pieces without the gaps and how can we bring on this toolkit the libraries of samples.
