A prompt appears asking for the fi rst point. Move the cursor to the second
point, another prompt appears (Fig. 3.36). Press the down button of the

The Dynamic Input method of constructing 2D drawings can equally as
well be used when constructing 3D solid models drawings (see Chapter 12
onwards).
Why use Dynamic Input?
Some operators may prefer constructing drawings without having to make
entries at the command line in response to tool prompts. By using DYN
drawings, whether in 2D or in 3D format, can be constructed purely from
operating and moving the mouse, entering coordinates at the command
line and pressing the down key of the keyboard when necessary.
