There are several functions in the sub menu as shown in Figure 5.5.7.
Figure 5.5.7 Section Cut
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.
l
Define a coordinate
system by using the options in the LCS dialog window.
l 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.
l 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.
l Enter the number of section planes along
the W-axis in the window, NUMBER OF SECTIONS.
l eta/DYNAFORM will create a part called SECTION containing all section lines.
2. LENGTH OF SECTION
This function allows the user to measure the arc lengths of a line.
There are three options in this function:
l CURSOR LOCATION
Select two points on a line. eta/DYNAFORM calculates the arc length between two points and prompts:
LINE SEGMENT LENGTH IS: xxx
l LINE
Select the desired line by cursor. The entire length of this section line will be calculated and given in the PROMPT window.
l REJECT LAST
Reject the last selection.
3. MEASURE ANGLE
This function allows the user to measure the angle between two segments on a line.
l Select the desired line by cursor.
l Select two points on the line to define the linear regression line 1 in red. The user can reset the selection by using REJECT LAST POINT.
l Select another two points on the line to define the regression line 2 in red. The user can reset the selection by using REJECT LAST POINT.
l eta/DYNAFORM calculates the angle between the two regression lines. The result is given in the PROMPT window.
4. SECTION ON/OFF
This function toggles all parts OFF except the section part. If toggled again, the parts that were initially displayed will be re-displayed.
