Howdy! I am trying to add simple line features, of specified lengths, to a map in Pro. I use the Create Features....Line tool. I click to place the starting vertex of the line. I then move off slightly and right click and choose the Direction and Distance tool. I enter a distance in feet, and a new vertex is added. However, the Shape_Length attribute shows a different length. For example, I create a line and enter the distance of 85 feet, the line is drawn but the Shape_Length field shows a value of 65.5.... When I use the measure tool, it to returns a distance of 65.5 feet. I started this project using the Public Parking solution. The map frame and solution feature services are in WGS 1984 Web Mercator Auxiliary Sphere. I have added other feature classes related to parking, parcels, city boundary, etc., some having either stateplane or GCS WGS 1984 spatial references. All register nicely as expected. I suspect I am having a disagreement between spatial references. I created a new feature line class in Web Mercator and created a line using 85 feet as the distance. The Shape_Length returns the length in meters, 25.908007 which equals 85 feet. I was hoping I could stay with stateplane, but it appears for accurate distances I need to be in the web mercator space. Am I correct or clueless?
