Converting Objects
into RF Obstacles
Use the graphics tools in the Insert RF Obstacle group box of the Edit
Content page to draw the RF obstacles and assign attenuation values
to them. This method is available for any floor plan. (See "Drawing RF
Obstacles" on page 132.)
Consider the following when creating RF obstacles:
Be aware if a CAD drawing contains overlapping objects. If you create
RF obstacles on objects that are on top of each other, the attenuation
is increased at that point. (3WXM sums the attenuation factors in dB.)
Grouping objects is useful if you want one attenuation factor for an
area on the floor.
You have several options when creating RF obstacles:
Convert all objects in a layer of a CAD drawing into RF obstacles.
Convert all objects in an area of the drawing into RF obstacles.
Convert multiple objects in the drawing into RF obstacles.
Convert grouped objects in the drawing into RF obstacles.
To create RF obstacles for all objects in a layer
3WXM preserves the layers defined in a CAD drawing. You can convert
all of the objects in the layer into a specific type of RF obstacle.
1 In the Layer Name column in the Edit Content page (in the Building
wizard), right-click the layer row in the table.
2 Select Create RF Obstacles. The Create RF Obstacle dialog box appears.
3 Go to "To use the Create RF Obstacle Dialog box" on page 130.
To create RF obstacles for an area in a drawing
1 Diagonally drag the cursor over the area where you want to create RF
obstacles.
2 Right-click, and select Create RF Obstacle. The Create RF Obstacle
dialog box appears.
3 Go to "To use the Create RF Obstacle Dialog box" on page 130.
