Area’s are defined by a series of small square dots called vertices and lines that connect them to define a shape. As you draw you define where each vertex is placed and the length of the line to the next vertex. Once the shape is closed...
After drawing an area it can be repositioned by dragging the centrex icon, seen in the center of the shape, to a new location. Clicking / tapping the centrex will also toggle line length labels on and off. If this FAQ didn’t answer your...
After drawing your first area, simply select the plus + symbol in the bottom right corner to add a new drawing layer. Each drawing layer supports one calculation (closed shape, length or angle). Repeat the process of adding a new layer and...
The angle tool is nested in the toolbar under the select tool (Mobile users will find it nested under the Pan tool). With the angle tool selected, begin by drawing the first arm of the angle you wish to measure (arm a). Now draw the second arm...
Yes. But you can’t select acres or hectares as a measurement system because these two units are already a measurement of squared area. Instead, just select an appropriate imperial (inches, feet, yards, miles) or metric (nanometers, millimeters...
Area and perimeter results are displayed in the bottom right corner when the shape you’re drawing is closed. I.e. the end vertex meets the starting vertex. For open shapes, the total length of the lines is displayed, as no area can be...
Yes. You’ll find the Print function under the main menu in the top right corner. Only the active layer in focus will print. If you wish to print all layers, select the sum layer (the eye symbol) in the results bar to display all drawing layers...
The math behind SketchAndCalc is called the shoelace formula or shoelace algorithm. It also goes by the name of Gauss’s area formula and the surveyor’s formula. SketchAndCalc is currently being trusted every day in fields from...
