How do we detect edges of items in a drawing
WebMar 12, 2024 · Edge detection is an image processing technique for finding the boundaries of an object in the given image. So, to summarize, the edges are the part of the image that represents the boundary or the shape of the object in the image. Also, the pixel values around the edge show a significant difference or a sudden change in the pixel values.

WebTry changing the graphics style (edges to shading with edges), and see if you can snap to an edge then. I find that my models don't always render correctly and this seems to help. After you get your leader on the edge, you can put it back to the display style you want. Shading with edges didn't work, but wireframe did.
