Arc

Available in: FREE, Plus, Pro Architectural

There two methods of drawing an arc with this command, 'Centre, Start & End' and '3 Points'. Draft it remembers the last method used.

The default method is 'Centre, Start & End', select the 'Draw Arc' button arc button and the command prompt reads:

Give Centre Point / (T)hree Point Arc:

Select the centre point of the arc using any of the snaps and input options.

After selecting the point a dynamic line is drawn from it to the cursor. This line is defining the radius of the arc and a dynamic circle is drawn around the centre point through the cursor position allowing you to visualise the size of the arc. The prompt now reads:

Give Start Point:

Select the start point of the arc using any of the snaps and input options.

After selecting the point the dynamic line continues to be drawn from the centre point to the cursor. However the radius and the start angle of the arc are now fixed. As you move the cursor a dynamic arc is drawn in an anti-clockwise direction from the start point around the centre point to the cursor.

The prompt now reads:

Give End Point:

Select the end point of the arc using any of the snaps and input options. The arc is now drawn.

To draw a three point arc select the 'Draw Arc' button arc button and the command prompt reads:
