Data
Specify the grid range
within which the centers of arcs will be located.
Grid
Spacing
Common spacing in both
directions.
Radius
Data
Specify the range of
radius.
Method
of using Arc Tangent Lines
Generate reference lines
which will become the tangents to arcs.
Arc
radius increment
Enter the increment
for generating arc radius.
Number
of Arc
Specify the number of
incremental tangents. From the grid points, shortest lines to the tangents
are generated.
Change
Tangent Direction
Rotate the tangent direction
by 90 degrees.
Method
of using Arc Radius and Length
Specify the range of
radii and length.
Method
of searching First Arc Radius
Shortest
Radius
Use the shortest arc
radius.
Passage
Point
Define a point through
which the arc will pass.
Arc
radius increment
Specify the increment
of arc radius to be increased from the first arc radius.
Number
of Arc
Specify the number of
incremental tangents. From the grid points, shortest lines to the tangents
are generated.
Layer
Set Limiting Passage
Specify a layer set
through which no arcs will be generated.
 After creating the supports, the dialog box
will close upon clicking.
