By Partha Sarkar In this particular example we will see how to access Civil 3D Surface Spot Elevation Child label style. Suppose there is a Surface Spot Elevation Child label style named "Foot Meter_Child" in a Civil 3D DWG file and we try to use the following VB.NET code snippet to find out the number…

By Partha Sarkar We can add boundaries to Civil 3D Surface object using the SurfaceDefinitionBoundaries class; this class encapsulates the boundary operation list for a surface. Note that, operations are stored in the order they are performed on the surface. SurfaceDefinitionBoundaries class has overloaded function AddBoundaries(). In the following example we will see how to…

By Partha Sarkar In some of the projects requirement, you may want to convert the Civil 3D SurveyFigure objects to AutoCAD geometric object like polyline and retain the curves, bulges etc. When you select a Civil 3D SurveyFigure object and call the LIST command in Civil 3D, you would see each segment type and associated…

By Partha Sarkar AutoCAD Civil 3D Profile type has a property named UpdateMode which can be used to get or set the update mode of the profile. Here is a note from the Civil 3D API reference document help file on Profile.UpdateMode property which I would like to draw your attention -  Gets for Superimposed,…

The main idea was how collect coordinate points using Mobile with GPS enabled devices running Android or iOS, then store and merge those at the Cloud to finally generate Civil 3D objects, like surfaces,…

By Partha Sarkar In my previous blog post we saw how quickly and easily we can upload and store a LandXML file in Windows Azure Cloud storage. In this post we will see how we can access our LandXML files stored in Cloud and use the same to create a TIN Surface in Civil 3D.…
