12.2.3. Draw Circles and Arcs

To create a circle or an arc, begin by selecting [Circle/Arc] in the SimCam menu. Next, choose between [Guide Circle] or [Drawing Circle/Arc]. Then, opt for [Center – Radius] if you have a known center coordinate and radius for the circle or arc, or select [Two or Three Points] if the center and radius are unknown.
 
 
The [Center – Radius] method is straightforward. Simply click or input the center point, followed by the radius. If you've chosen to create a [Drawing Circle/Arc], you'll also be prompted to enter the start and end angles.
 
 
In such a situation, simply hold down the SHIFT key and press Enter to generate a complete circle.
 
 
Additionally, be aware that when choosing the end angle, you can reverse the arc's direction (clockwise/counterclockwise) by pressing the Space bar on your keyboard.
 
Use the following methods to establish the center point:
 
 
 
 
Click an Object (Only circles, the new circle will get the same center as the one you click on.)
 
The second method is more sophisticated and offers additional options, including:
 
1. Creating a circle using three known points along the circle's edge (neither the circle's center nor radius are required).
 
Select [Circle/Arc] (followed by the circle/arc type) and then [Two or Three Points] from the SimCam menu.
 
Click, input, or snap click three known points located on the circle's border.
 
 
 
 
2. Creating a circle tangential to a line or another circle with a known center:
 
Select [Circle/Arc] (followed by the circle/arc type) and then [Two or Three Points] from the SimCam menu.
Click on a line or a circle.
Click, input, or snap click the circle's center point.
 
 
 
3. Crating a circle with a known radius that is tangential to two objects:
 
Select [Circle/Arc] (followed by the circle/arc type) and then [Two or Three Points] from the SimCam menu.
Click on two different objects, such as a line and a circle.
Choose [Enter radius] to input the radius or drag the mouse until the desired radius is displayed at the cursor, then click.
 
 
In conclusion, drawing circles and arcs in the SimCam software can be achieved using various methods, catering to different requirements and levels of complexity. By understanding the different options for creating circles and arcs, users can efficiently design and modify their projects with ease. Mastering these techniques will help users make the most of the SimCam software and enhance their overall drafting experience.
