Cotar desenho automaticamente

[Anonymous]

Pessoal, Tenho uma Polyline com mais de 1000 pontos eu preciso cotar do P1 ao P2 do P2 ao P3 do P3 ao P4 e assim por diante, como esses pontos estão por coordenadas geográficas fiquei a pensar se existe a possibilidade de algum comando ou lisp que possa me ajudar a cotar essas polyline.

Olá,

Experimente este LISP (consulte o anexo). Espero que seja o que você estava procurando.

This is not as simple as it appears. If you want to convert from geographic coordinates such as Lat/Longs degrees, to projected coordinates, for example UTM meters, then you will have to know your 'target' projection.

The target projection is not one-size-fits-all like you may think. Your target projection varies according to your map's location. Examples include, but are not limited to, UTM Zone, a Country system, a Continental or Regional system, a portion of a country such as east zone or west zone, or something else. You will also have to determine which 'version year' of a coordinate system you wish to target because coordinate systems are often revised, updated or improved  due to better information and/or higher accuracy. As you can see, a lisp is not an efficient way to accommodate all factors needed to transform your coordinates from Lat/Long degrees to X,Y-meters.

You are better off using  AutoCad Civil 3D or Map 3D, Unlike Vanilla AutoCad, both programs can handle transformations due to their built-in Coordinate System Libraries which give them geospatial capabilities.

Alternatively you can use an online converter such as >>ZONUMS<< You can even paste a csv file into this online converter

Whether you use lisp, Civil, Map or an online converter to perform the transformation, you will still have to determine your desired projection.
