• If the mouse button released to stop drawing then the line will turn black.

Editing a Freehand curve: Users can change the length of a curve entity as long as it doesn’t bind a face and here are the following steps to edit a curve:

• At first, the Move Tool is selected; it changes the cursor to a four-way arrow.
• The cursor needs to hover over the curve to locate an end point.
• Next the cursor needs to click and drag at the end point to adjust the curve. When the drawing is done, users need to release the mouse.
