Here's a new one. I am adding graphic patches to 8.5 x 11" layouts, so my text can be more easily read over linear features like roads. These are little polygons: 1/12" x 1/8" or less. Adding either a polygon or a rectangle, I digitize my small patch, double click to finish it off, and the graphic immediately grows to about 3" x 3". If it is a polygon, no matter what shape I digitize, it reforms and grows to a 4-vertex trapezium of the same size and shape as the last failed polygon did, so there is no resizing it to fit (especially since we can't edit vertices in graphics yet). If I digitize at about 1/8" x 1/8", the polygon I digitize remains the same size and shape as I drew it. I can resize rectangles when they will work for the patch I need, but that is a bother, and really, this should not be a problem!
This makes me think this is a grain problem, but didn't grain tolerance go the way of coverages? I admit being far more savvy with ArcGIS (and Info for that matter) than Pro, so I am still learning the nuances. I have turned off all snapping that I can think of. Can I change the grain tolerance? Other ideas?
