To draw RF obstacles, you use the Insert RF Obstacle box of the Edit
Content page. Follow these steps.
1 In the Insert RF Obstacle group box of the Edit Content page, click one of
the following icons and draw the object as described:
Object
(circle)
(square)
(parallelogram)
(polygon)
(line)
Using an object other than a line to represent an RF obstacle's dimensions
does not materially affect the calculation of RF attenuation. When 3WXM
calculates attenuation along any vector passing through the obstacle, it
counts the obstacle's RF attenuation only once, regardless of the floor
space it occupies.
Action
Diagonally drag the cursor over the area where you want
the circle to appear.
Diagonally drag the cursor over the area where you want
the square to appear.
3WXM treats squares as one solid object when calculating
RF attenuation. To draw a square outline, draw four lines
in a square shape, which are treated as four separate RF
obstacles.
1 Click at a vertex, and drag the cursor to the next
connected vertex.
2 Click again, and drag the cursor until the parallelogram
takes the shape you want.
3 Click to finish.
1 Click at a vertex, then move the cursor to the next
vertex.
2 Repeat until the polygon takes the shape you want.
For a polygon with n sides, click n-1 additional times at
the vertices. For example, to draw a 7-sided polygon,
click at 6 vertices.
3 At the last vertex before completing the shape,
Right-click to complete the polygon.
3WXM supports concave polygons. A concave polygon
contains an internal angle greater than 180 degrees.
1 Click at the start of the line.
2 Drag the cursor to the end of the line.
3 Click to finish.
