This function
allows the user to generate arcs. As illustrated in Figure
Figure
1. CENTER AND RADIUS
• Define a LCS. Refer to Section 11.15, LOCAL COORDINATE SYSTEM, for information about defining LCS. The center of the arc will be positioned at the origin of LSC, and the arc will be in the UV plane of the LCS.
•
Key in the values in the ARC
PARAMETER dialog box as illustrated in Figure
Figure
RAD: Radius of arc
TH1: Beginning angle from U-axis
TH2: Ending angle from U-axis
INC: Angle increment between points (default is 5 degrees) on an arc
2. TANGENT TO 2 LINES
This function allows the user to create an arc that is tangent to 2 lines.
•
Select two intersecting lines.
Refer to Section
•
Enter the radius in the input
field of RADIUS OF ARC dialog box as illustrated in Figure

3.
Create by THROUGH
This function allows the user to create an arc through three non-collinear points/nodes.
• Select three points/nodes. After the third point/node is selected, the arc and its center will be generated.
