Arc Grid Line

An arc grid line can be constructed in two ways:

• By specifying three points on the arc ;
• By specifying start, center, end points .

To create Arc by specifying three points:

1. On the tools panel, click Designation – the Grid line tool.
2. Click the Arc by specifying three points construction mode.
3. On the work plane, specify the initial point of Arc grid line.
4. Specify the second point or type values in the dynamic input fields.
5. Specify the third point in the same way.

To build Arc by specifying a circle arc center point:

1. Select the Arc by specifying start, center, end points construction mode.
2. On the work plane, specify the initial point of Arc grid line.
3. Specify the circle arc center point. You can also type the radius and radius rotate angle values in the dynamic input fields.
4. Specify the end point in the same way.
