1. CUT SECTION
This function allows the user to generate section lines that are intersections of the displayed F.E. mesh with a set of parallel planes.
Create the coordinate system by using the options in the LCS dialog window.
Enter the starting location in W-COORDINATE for the first plane in the window SECTION LOCATION or click the "STARTING SECTION" button to select a node or point for the location.
Enter the end location in W-COORDINATE for the last plane that is perpendicular to the W-axis or click the "END LOCATION" button to select a node or point for the location.
Enter the number of section planes along the W-axis in the window NUMBER OF SECTIONS.
eta/DYNAFORM will create a part called SECTION containing all section lines.
2. LENGTH OF SECTION
This function allows the user to measure the length of line.
There are three options in this function:
CURSOR LOCATION
Select two points on a line. eta/DYNAFORM calculates the arc length between two points and prompts:
LINE SEGMENT LENGTH IS: xxx
LINE
Select desired line by cursor. The entire length of this section line will be calculated and given in the prompt window.
REJECT LAST
Reject last selection.
3. MEASURE ANGLE
This function allows the user to measure the angle between two segments on a line.
Select desired line by cursor.
Select two points on the line to define linear regression line 1 in red. The user can reset the selection by using REJECT LAST POINT.
Select another two points on the line to define regression line 2 in red. The user can reset the selection by using REJECT LAST POINT.
eta/DYNAFORM calculates the angle between the two regression lines just defined. The result is given in the prompt window.
