Start Node NumberAssign a number to the new starting node created together with new elements in the Model Window. This number is auto-set to the largest node number in use +1. To modify this item, click and select an option to specify a desired number.
Start Element NumberAssign a new starting element number. This number is auto-set to the largest element number in use +1. To modify this item, click and select an option to specify a desired number.
Curve TypeSelect the shape of a curve onto which line elements will be created and the method of defining the curve. Arc by

by Center and 2 points Ellipse
by Center and 2 points Parabolic

Assign the type of line elements to be created along the curve
Material
Select a material property number, or
select a material property name provided that the material property data
have been already defined.
No.: Type in a number on the keyboard or use the mouse to enter the number
Name: Select a material property name
Click to add, inquire, modify or delete material property data. Material properties can be entered either before or after creating elements.
Section
Select a section number, or select a section
name provided that the section data have been already defined.
No.: Type in a number on the keyboard or use the mouse to enter the number
Name: Select a section name
Click to add, inquire, modify or delete the section data. Section data can be entered either before or after creating elements.
Orientation
Beta Angle: Enter a Beta Angle to assign the sectional orientation of the line elements.
Define a curve on which new line elements will be created.
Number of Segments: Number of segments in the curve to define new elements
The data entry items for each method of
defining the curves are as follows :
Arc by 3 points
Arc End Point: Assign the method of defining the end of the arc P3: Create elements up to the 3rd point on the arc Angle: Enter the angle of the arc within which new elements will be created
The arc is created in the direction determined by the sequential direction of P1, P2 & P3.
|
Arc by Center and 2 points
Arc End Point: Assign the method of defining the end of the arc P2: Create line elements up to the fictitious line connecting P2 and the center of the arc center Angle: Enter the angle of the arc within which new elements will be created
The arc is created in the direction along the curve from P1 to P2 following the shorter distance. To create the arc in the longer arc direction, Angle is used to control the direction. Note
|
Circle by 3 points
The circle is created in the direction determined by the sequential direction of P1, P2 & P3.
|
Circle by Center and 2 points
|
Ellipse by Center and 2 points
Semi-Ellipse: To form a semi-ellipse
|
Parabolic Curve by 3 points
Divide by Equal distance on Curve: Divide the curve into equal segments Projecting line: Divide the curve into equal segments along the length projected on UCS (GCS) x-axis
|
Cubic Curve by 4 points
|
Note
The Local Directions of the line elements are
defined by the sequential direction of P1, P2 & P3.
Node: when existing nodes are on the line elements being created, the elements are divided at the existing nodes.
Element: when newly created line elements intersect with existing line elements, nodes are automatically created and the line elements are divided at the intersection points.
