Where can I get cad drawings of urban planning drawings?

You can download them from major picture websites, or you can ask for them from the planning bureau through connections, but they are generally not given casually.

Moreover, the city planning map only has a rough outline, and there are basically no detailed CAD drawings. Even the CAD drawings of the top view may not match.

The general planning drawing is the planning drawing, and the CAD of the real estate hotel must be found separately.
