Introduction

This topic will explain the Arc 3 Entities function, will explain where to find the function, and explain the options found in it. This topic will also explain creation with quick steps and examples, and provide links to related topics.

The Arc 3 Entities Function

The Arc 3 Entities function is used to create arcs by selecting 3 entities in the graphics area which will create an arc tangent to each. This can be accomplished by picking three entities in the graphics area.

Examples

Example 1

1. In the Quick Access Toolbar, click New.
   
   
2. In the Entity group of the Create 2D ribbon, click Point.
   
   
3. Place three points anywhere in the graphics area.
   
   
4. In the Entity group, of the Create 2D ribbon, click the down arrow under Arc, and select Arc 3 Entities.
   
   
5. Left click on one of the three points created previously.

   With 3 entities selected, the preview is displayed.
   
   
   
   The order of the entities also helps determine the result, but the order can also be adjusted in the Selected Geometry list.
   
   
8. Click the first entity listed in the Selected Geometry list.
   
   
   
   The entity highlights in the graphics area.
   
   
9. Use the arrows next to Selected Geometry list to adjust its position in the list.
   
   
   
   
10. Click OK when the desired result is shown in the preview.
    
    
    
    The arc is created.
