You can create construction circles that are parallel to the view plane by picking two points, or you can create construction circles by picking three points in the 3D space in the model.

1. On the Edit tab, click Construction object > Circle.
2. On the contextual toolbar that appears, click a button to specify which set of points you want to pick:

   

   • Click , and then pick the center point and a point to define the radius of the circle.

     Tekla Structures creates the circle parallel to the view plane.

   • Click , and then pick three points: the center point, a point to define the radius, and a point to define the plane of the circle.

   • Click , and then pick three points along the arc of the circle.

   Tekla Structures creates the circle using the points you picked and using the current properties. Tekla Structures also indicates the center point of the circle with an X in the model.

3. To end the command, press Esc.
4. To modify the construction circle properties, double-click the circle in the model.

   The circle properties are shown in the property pane.

   1. Select a color for the circle.
   2. Select a line type for the circle.
   3. Click Modify.
