How create AutoCAD polyline feature from industry model feature in AutoCAD .net

[Anonymous]

Hi All,

I want to create AutoCAD polyline feature from industry model feature through AutoCAD .net.

Industry model feature will have the Linestring with arc segment and Polygon with Arcsegment. i am having issue with reading and creating arc segment and i dont know how to do this.

Please note that, We should not use out of box command (i.e like MapextractGeometryFeature). i want to do this through .net code.

Please help us any sample code to create polyline with arcsegments from reading coordinates from industry model feature.

Thanks inadvance.

Regards,

Dayalan

Autodesk.Map.IM.GeometryConverter.AutoCAD.Converter converter = new Autodesk.Map.IM.GeometryConverter.AutoCAD.Converter();

object entity = converter.ConvertTo(feature.Geometry);

Autodesk.AutoCAD.DatabaseServices.Polyline polyline = entity as Autodesk.AutoCAD.DatabaseServices.Polyline;

//Append the new polyline to the block table record
//and add the newly created object via a transaction
//just as you would when creating any new AutoCAD entity

Hi..

 I saw few posts here for importing spatial data into autocad and this is what i have to do currently.. I already developed VBA code for the same but it takes lot of time to compelte. please let me know how to do this .net? autocad command "MAPIMPORTFDO" imports the data into cad quickly but it draws polylines as lines. how to implement this FDOIMPORT in C# and convert lines to polylines and make this retreival of data faster? 

Thanks in Advance for your valuable feedbacks.

Hi,

is this the same theme?

Do you have the road Polygons in a industry model?

If not please create a new theme.

For your polygons from traffic technical view, it's not the right way to generate the axis of the streets out of the area polygons.

This depends of direction, parking slots, slope curves and so on included in the area polygons.

Otherwise your routing program will not work correctly, sorry. Normally the provider of the data should have the street axis data too.
