When function Plane generator is started, a new toolbar is added to the bar just above the command line.
Buttons of the toolbar has the following meaning (from the left).
|
New circle – centre, radius point |
Once button [New circle] is pressed a short sub-toolbar is offered. This is the first of the functions on this sub-toolbar. The user must define the centre point and a point on the circle that specifies the radius. |
|
New circle – 3 points |
Once button [New circle] is pressed a short sub-toolbar is offered. This is the second of the functions on this sub-toolbar. The user must input three points located on the circle. |
|
New rectangle |
The user must define two opposite corners of a rectangle. |
|
New polygon |
The user must define individual vertices of the polygon. |
|
New straight line |
The following edge (segment) of the currently defined polygon will be a straight line. |
|
The following edge (segment) of the currently defined polygon will be a circular arc (the intermediate point and end point of the circular segment must be input). |
|
|
New parabolic arc |
The following edge will be of a parabolic shape. Follow the procedure for the input of a parabolic beam. |
|
New Bezier |
The following edge will be formed by a Bezier curve. Follow the procedure for the input of a "Bezier-curve" beam. |
|
The following edge will be formed by a spline. Follow the procedure for the input of a "spline" beam. |
|
|
Select line |
This button is useful if a new polygon is supposed to follow the shape of a previously defined polygon. The user does not have to pick all the vertices of the new polygon, but may select existing edges of the already input polygon. See the example below. |
|
Step back |
This button goes one step back in the definition of the polygon. For example: If a polygon is being defined, the last vertex is removed. Or, if a circle is being defined by means of three points and two points have been defined so far, this function removes the second point of the circle but leaves the first circle point unaffected. |
Example for Select line function
Let’s assume that a polygon has been input as shown below.
Another polygon is supposed to follow the circular part of the first polygon. The procedure may be:
Start function Plane load.
Input the first point to the right of vertex P4 of the defined polygon.
Input the second point directly in vertex P4.
Press button [Select line] on the toolbar.
Select edge P4-P5 of the first polygon.
Select edge P5-P7 of the first polygon.
Select edge P7-P6 of the first polygon.
Press button [New straight] line on the toolbar.
Input the remaining vertices of the new polygon.
