HFSS15: Drawing a Helix
录入：edatop.com 点击：
A helix is a 3D spiral object created by sweeping a 1D or 2D object along a vector. Sweeping a 1D object results in a hollow 3D object. Sweeping a 2D sheet object results in a 3D solid object.
1. Select the 1D or 2D object you want to sweep to form a helix.
2. Click Draw>Helix
.
3. Draw the vector you want to sweep the object along. The two points that describe the vector affect axis direction only and not the helix length. The helix length is determined when you enter the pitch and number of turns in the Pitch and Turns text boxes. The initial radius of the helix is determined by the axis position relative to the object being swept.
a. Select the start point by clicking the point or typing its coordinates in the X, Y, and Z text boxes.
b. Select the endpoint by clicking the point or typing its coordinates relative to the start point in the dX, dY, and dZ boxes.
The Helix dialog box appears.
4. For Turn Direction, select Right hand if the turn direction is clockwise and Left hand if the turn direction is counter-clockwise.
5. In the Pitch text box, type the distance between each turn in the helix, and click a unit in the pull-down list.
6. In the Turns text box, type the number of complete revolutions the object will make along the vector.
7. In the Radius Change per Turn text box, type a number for the increase in the radius and select the units from the pull-down list.
8. After you set these values, the selected object is swept along the vector to form a helix. The original object you swept is deleted.
If the Modeler option for editing properties of new primitives is checked, the Properties dialog box appears, enabling you to modify the object’s properties.
9. Click OK.
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. For details about these commands see: Technical Notes, "Surface Approximations" and related sections, Rectilinear Elements and Curvilinear Elements, "Modifying Surface Approximations," and "Guidelines for Modifying Surface Approximations" |
