Google Street View vanuit een tekening

AutoLISP is een taal die in januari 1986 door Autodesk in AutoCAD werd geïntroduceerd. AutoLISP als taal is gebleven en wordt veel gebruikt als ​​primaire programmeertaal voor maatwerk oplossingen. Deze code rekent de RD positie om naar lat/lon om deze vervolgens in Google maps weer te geven op de kaart en met Street View. Zo krijg je snel inzicht in de locatie van het ontwerp (mits geo-gerefereerd). Het ondersteunt tekeningen gemaakt in zowel millimeter [mm] als meter [m]. Let even op juiste instelling van [Units] in uw tekening. Deze lispcode is getest en te gebruiken in AutoCAD, BricsCAD en GstarCAD
