Material / Section / Orientation
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.
Curve Definition
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
P1: Enter the coordinates of the starting point of
the arc
P2, P3: Enter the coordinates of two points on the
arc
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
C: Enter the coordinates of the center of the arc
P1: Enter the coordinates of a particular point on
the arc
P2: Create line elements up to the fictitious line
connecting P2 and the arc center.
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
The arc cannot be created if P1, C and P2 are on a straight line. In such
a case, use Angle to create the arc.
Circle by 3 points
P1: Enter the coordinates of the starting point of
a circle
P2, P3: Enter the coordinates of two points on the
circle
The circle is created in the direction determined
by the sequential direction of P1, P2 & P3.
Circle by Center and
2 points
C: Enter the coordinates of the center of a circle
P1: Enter the coordinates of the starting point of
the circle
P2: Assign a point on the plane of the circle
Ellipse by Center and
2 points
Semi-Ellipse:
To form a semi-ellipse
C: Enter the coordinates of the center of an ellipse
P1: Enter the coordinates of the starting point on
the axis of the longer dimension
P2: Enter the coordinates of a point on the 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
P1: Enter the coordinates of the starting point of
a parabola
P2, P3: Enter the coordinates of two points on the
parabola
Cubic Curve by 4 points
P1: Enter the coordinates of the starting point of
a cubic curve
P2, P3, P4: Enter the coordinates of 3 points
on the cubic curve
Note
The Local Directions of the line elements are defined by the sequential
direction of P1, P2 & P3.
Intersect
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.
