And by line I suppose I really mean a straight line (slope between two points). I know it's possible to draw a slope/aspect model with DEM, but the lines I would be drawing traverse these slopes.&nbsp;</P> Thu, 06 Jan 2022 14:25:36 GMT https://community.esri.com/t5/arcgis-pro-questions/drawing-a-line-feature-at-a-constant-slope-using/m-p/1131187#M49624 Hemlock_Grove 2022-01-06T14:25:36Z
