Adding vector points whith contour edit tool

I scanned a drawing that I imported and vectorized with texture.
Now I have to outline the drawing with vector points using the
contour edit tool…but how do I do that.?..when I click with
the contour edit tool a red line with a blue dot in each corner appears around the drawing, but how do I add blue dots around
the whole drawing? Will someone please show me.

Hi,

When you vectorize and decide to use a texture, there is no way to add control points or to edit your drawing. It become a big chunk and stays like it.

You need to use a black and white or gray drawing without checking the texture option. This will produce a vector drawing with strokes already drawn based on the source drawing.

I hope this helps.
Please, let me know.
