Hi Stefan, While exploring the workbench, I noticed that when creating a polygon model, non-interactive 2D contour is also displayed in the 2D views for the corresponding generated 3D model: [image: image.png]
I wanted to ask if it would be a good idea to replace this non-interactive contour with an interactive one by assigning a custom interactor to it?
