Drawing a Circle
Draw a circle by selecting a center point and a radius. Circles are drawn as true surfaces in the modeler.
- On the Draw
menu, click Circle.
- Select the center point of the circle in one of the following ways:
- Click the point.
- Type the point’s coordinates in the text boxes in the status bar.
- Specify the radius by selecting a point on the circle’s circumference in one of the following ways:
- Click the point.
- Type the coordinates of the point relative to the center point in the dX, dY, and dZ boxes, where d is the distance from the previously selected point.
- Click OK.
If the Modeler option for editing properties of new primitives is checked, the Properties window appears, in which you can modify the object’s attributes.
If the Automatically cover closed polyline option is selected in the Modeler Options window, the circle will be covered, resulting in a 2D sheet object. Otherwise it will be a closed 1D polyline object.
Note: The 3D Geometry
Modeler permits drawing of true-curved objects. However, the solution
will be obtained with a tetrahedral mesh which conforms to the true surface
only within the limits identified by certain mesh settings. The modeler
has default settings for this conformance which is a reasonable trade-off
between solution speed and solution quality for most objects, but may
not be ideal for all such objects. High-aspect ratio curves structures,
such as helices with narrow and curved cross-sections, may benefit from
user control of the faceting values.
