When you build a plan view drawing, you can add shapes, locations, and lines. However, if you do not want to use conventional shapes and lines, you can draw freehand lines and shapes. This may help you quickly sketch the site layout and note project requirements during takeoffs.
To draw freehand lines or shapes, open a plan view drawing, click the "Draw" icon on the toolbar, click a spot in the drawing, and draw the line or shape.
You can get creative and:
Draw curved and dotted lines, parentheses, mathematical operators, and other symbols
Draw arrows and point them to vital items on the layout
Draw shapes that look like callouts, then place text boxes inside them
Cloud treats freehand shapes as polygons. So, you can use all the regular shape-editing options, such as fill color and side thickness, for freehand shapes.
