Hi Goral,

Please edit your post, it looks you make your text as code, so it’s not easy to read.

And you hadn’t put your question in corresponding sub-forum, we don’t know which product you are using.

Could you please attach your simple sample here, so we can know how you had implemented here and help you find the problem, from your description your scenario is not clearly.

Regards,

Don

Hi Goral,

I still hadn’t found the SnapToEditInteractiveOverlay class you mentioned.

I think if you want to get more help on this problem we need your sample, based on that we can directly start works for the issue and reduce the communication time.

And if that’s a new requirement, I think you should want to get support from our ticket system or professional service, because in forum we focus on solve more basic problems and simple bugs.

Hi Goral,

Attached is the sample, please check it out. There is a sample “HowDoISamples” on our wiki, I guess it can help you.

ThinkGeo Docs. After you run the sample and then please expand the “Editing Feature Layers” and click “Track and edit shapes” item, it allows us to edit and track the shapes you want, like below.

Hi Goral,

The problem is you still hadn’t paste the code of SnapToLayerEditInteractiveOverlay.

If you implement the vertexadded event, you can get the feature directly from the event args.

private void VertexAdded(object sender, VertexAddedEditInteractiveOverlayEventArgs e)
{
e.AffectedVertexFeature; // This is what you want
}

Don
