So I want to enter WGS geographic coordinates (lat/lon in decimal degrees) into Civil 3D... I use Map command adesetcrdsys... I choose LL84 as coordinate system... use _AeccCreatePointManual with 'LL option... C3D creates a point...
Now when I draw some lines connecting civil points created this way, and do PublishKML, lines in Google Earth are some 8000 metres off... Is setting LL84 as coordinate system right option? Or is it something wrong with Google Earth export? Thank you for your reply!
While I believe that using adesetcrdsys might work. The usual way to set a geodetic system in Civil 3D is to right click the drawing name on the settings tab of the prospector and use the Units and Zone tab. Check that and if it doesn't match the system you want. Set it accordingly.
I'm not sure if this achieves the same thing or not, but I do MapCsAssign (map coordinate system assign). So then any features you add using your local coordinate system will be correctly placed on bing maps or whatever.
Could someone verify if LL84 is the right coordinate system to assign when entering WGS84 lat/lon? And if so, what command do I choose when entering points? easting/northing? grid easting/grid northing? or lat/lon?
LL84 is the right coordinate system to assign when entering WGS84 lat/lon?
Sorry, but I can't understand why you wanna enter coordinates in Lat/Long format: never heard anybody working in that way, sir.
You'd simply enter your classic meters/feet coords, then perform a _MAPEXPORT to a LL84 shapefile, finally you convert it to .KML by means of one of the several free SHP2KML tools, or with the powerful opensource Qgis.
Because I don't have projected coordinates... I only have WGS84 lat/lon... Export to shapefile, then convert to KML? Doesn't it look like one step too many given the Civil 3D (or Map) built-in PublishKML function?
I always create a .csv file and then import the points that way. You can make a new point file format that will recognize the Lat and Long coordinates. Make sure you assign point numbers in the csv file
Sorry, I've no idea if it's a new command or not, I've only just started using c3d earlier this year. It's in the planning and analysis workspace
