Re-draw attached drawing in AutoCAD. All elements should be drawn as editable paths.
Drawing can be simplified to reflect only elements that have dimensions in original drawing.
There should be 2 layers in final DWG:
1. drawing
2. dimensions
I'm a professional Architectural Model Maker for over 10 years and I work with complicated drawing both 2D and 3D from Architects everyday and design the model kit for final laser machine processing files.
