File encl. In Ss1 there are four triangles. Three of these have extra node(s) interior to a line that defines a triangle. I don’t know how these originated. If I Delete a problem line, the nodes remain after the Delete operation. Ss2 If I redraw the lines, the nodes return in same places and we are back to Ss1.

Why & what to do to correct?

Thanks

Tommy

You have extra but very small unnecessary lines. You need to zoom in to see them. Just delete those and you are good to go.

Thank you. Sometimes when I Zoom with two Fingers the zoom snaps back and you have to be persistent to see small lines like these…
