Hi,
I’m a newbie. I’m developing new standalone tool to build model 3D (Steel Bridge). Could I use Visual Studio (C# WPF) to create 3D lines in speckle and view 3D model on website? Could you give me simple example to do that. Just create 3d line and send to speckle, and see it on website?
Thanks!
One example send room boundaries from revit :

Hey @kt.developer.2022 ,
Here’s a very simple C# sample console app that does just that: GitHub - teocomi/speckle-lines-sample: quick sample on using speckle's api to create some lines
Any questions just ask!
Thanks very much. That’s exactly what I want!
Hi Teocomi,
Based on your sample, I try to send 2 lines with my account and stream. But It doesn’t work. Could you help me?
The my code is shown as below:
using Speckle.Core.Credentials;
using Speckle.Core.Transports;
using Speckle.Core.Api;
using Speckle.Core.Models;
using Speckle.Core.Transports;
var line1 = new Objects.Geometry.Line(new Objects.Geometry.Point(0, 0, 0), new Objects.Geometry.Point(100, -200, 50));
var line2 = new Objects.Geometry.Line(new Objects.Geometry.Point(0, 0, 0), new Objects.Geometry.Point(500, 100, 600));
var commitData = new Base();
commitData["data"] = new List<Base> { line1, line2 };
var account = new Account();
account.token = "REMOVED-FOR-SECURITY";
account.serverInfo = new ServerInfo
{
url = "https://speckle.xyz/"
};
var stream = "https://speckle.xyz/streams/1927593f17";
var streamId = "1927593f17";
var branchName = "main";
var client = new Client(account);
var transport = new ServerTransport(account, streamId);
var objectId = await Operations.Send(
commitData,
new List<ITransport> { transport },
disposeTransports: true);
var commitId = await client.CommitCreate(
new CommitCreateInput
{
streamId = streamId,
branchName = branchName,
objectId = objectId,
message = "Hello"
});
System.Diagnostics.Process.Start(
String.Format(@"https://speckle.xyz/streams/1927593f17/commits/{commitId}") );
Could you describe “it doesn’t work”?
Doesn’t send?
Doesn’t add lines?
Doesn’t authenticate?
I’ll look at what you have there in the meantime.
Hi Jonathon,
I use visual studio, after I run this code and check in the stream on speckle website. No data sent to stream.
It working in my side :
// See https://aka.ms/new-console-template for more information
using Speckle.Core.Credentials;
using Speckle.Core.Transports;
using Speckle.Core.Api;
using Speckle.Core.Models;
Console.WriteLine("Hello, Speckle!");
var line1 = new Objects.Geometry.Line(new Objects.Geometry.Point(0, 0, 0), new Objects.Geometry.Point(100, -200, 50));
var line2 = new Objects.Geometry.Line(new Objects.Geometry.Point(0, 0, 0), new Objects.Geometry.Point(500, 100, 600));
var commitData = new Base();
commitData["data"] = new List<Base> { line1, line2 };
var account = new Account();
account.token = "your token";
account.serverInfo = new ServerInfo
{
url = "https://speckle.xyz/"
};
var streamId = "4afea2f6c6";
var branchName = "main";
var client = new Client(account);
var transport = new ServerTransport(account, streamId);
var objectId = await Operations.Send(
commitData,
new List<ITransport> { transport },
disposeTransports: true);
var commitId = await client.CommitCreate(
new CommitCreateInput
{
streamId = streamId,
branchName = branchName,
objectId = objectId,
message = "Hello"
});
Console.WriteLine($"https://speckle.xyz/streams/{streamId}");
Thanks. But from my side, I used the same your code exception some changes about token and streamId, I got the error as below:
Could you help me?
This is my visual studio project I use to test.

You can try with SDK source from here :
Random thought but… can you double check your token has the correct scopes to read/write streams? It should have streams:read if you want to access stream data, and stream:write if you want to be able to make commits.
If you don’t, then you can create a new token and add those in the scopes dropdown.
