I followed a few simple examples provided by the rhino. But not sure how to call this
/rhino/geometry/hiddenlinedrawingparameters/new how do i call this?
I get this error “The type or namespace name ‘HiddenLineDrawingParameters’ could not be found”. Since HiddenLineDrawingParameters is no available in rhino3dm.
var hld_params = new HiddenLineDrawingParameters
Hi @Rama_Shashank,
Here is an example of using the HiddenLineDrawing API in RhinoCommon.
Note, this functionality is not available in Rhino3dm.

Ok, we don’t want to use RhinoCommon.
Instead, use the API provided in RhinoCompute to get the desired result.
I am able to call few API, but got stuck in here
public static void Main(string[] args)
{
ComputeServer.WebAddress = "http://localhost:5000/";
File3dm doc = File3dm.Read(@"C:\SRS\02-Templates\TestGeometry.3dm");
IEnumerator<File3dmObject> ienum = doc.Objects.GetEnumerator();
var hld_params = ComputeServer.Post<dynamic>("rhino/geometry/hiddenlinedrawingparameters/new");
var parms1 = new object[2]; parms1[0] = hld_params; parms1[1] = false;
hld_params = ComputeServer.Post<dynamic>("rhino/geometry/hiddenlinedrawingparameters/setincludetangentedges", parms1);
var parms2 = new object[2];parms2[0] = hld_params;
parms2[1] = doc.AllViews.FindName("Perspective").Viewport;
var t = ComputeServer.Post<dynamic>("rhino/geometry/hiddenlinedrawingparameters/setviewport", parms2);
