Hi,

I have created a dialog plugin that creates objects into the document.
The dialog creates the objects after I click a button.

I would like to add some kind of preview function so I can see where the objects will be placed, by drawing markers into the editor view.

As the GeDialog doesn't have access to the editors BaseDraw I used the following code

  
BaseDocument *doc = GetActiveDocument();  
BaseDraw *bd = doc->GetActiveBaseDraw();  
bd->Circle2D(100,100, 100);  

But nothing shows in the editor windows. Perhaps C4D is refreshing thus removing what I am trying to draw. Im not sure.

I have never used GetActiveBaseDraw before, so I'm wondering If I am doing this correctly.

Any help would be apreciated
Thanks

I think the best way is to make a custom SceneHookData that you can use to draw into the editor. SceneHookData::Draw() will be called every redraw. Make sure that it doesn't hog any resources when your dialog isn't open!
