Drawing a Cone
Draw a cone by selecting the center point and radius of the cone’s base circle, then specifying the radius of the cone’s top circle and the cone’s height. Cones are drawn as true surfaces in the modeler.
- Click Draw > Cone.
- Select the center point of the cone’s base 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 of the cone’s base circle by selecting a point on the base circle’s circumference. Select the point 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.
- Specify the radius of the cone’s top circle by selecting a point on its circumference. Select the point by clicking it or typing its coordinates in the dX, dY, and dZ boxes.
- Specify the height of the cone by selecting a point on the axis perpendicular to the base circle’s plane. Select the point by clicking the point or typing the coordinates in the dX, dY, and dZ boxes.
- Click OK.
To create an apex, select the same center point as the cone’s base circle.
If the Modeler option for editing properties of new primitives is checked, the Properties window appears, in which you can modify the object’s properties.
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.
