I will help you get that image or pdf you have to the real dimensions of the objects in it so you can start adding the things you want in scale.
I can scale and redraw that image or pdf so you can edit it later. If you want to make any modifications to a floor plan you were provided with, this is the gig for you. I could help you with that modification if you want.
Besides scaling and redrawing your image or pdf, the best configuration of furniture will be added to the plan. I will analyze the spaces in the project so the furniture is not an obstacle but gives a better conception of the space.
