Specifying the RF Characteristics of a Floor 129■ Use the graphics tools in the Insert RF Obstacle group box of the EditContent page to draw the RF obstacles and assign attenuation valuesto them. This method is available for any floor plan. (See “Drawing RFObstacles” on page 132.)Recommendations Consider the following when creating RF obstacles:■ Be aware if a CAD drawing contains overlapping objects. If you createRF obstacles on objects that are on top of each other, the attenuationis increased at that point. (3WXM sums the attenuation factors in dB.)■ Grouping objects is useful if you want one attenuation factor for anarea on the floor.Converting Objectsinto RF ObstaclesYou 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 layer3WXM preserves the layers defined in a CAD drawing. You can convertall 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 Buildingwizard), 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 drawing1 Diagonally drag the cursor over the area where you want to create RFobstacles.2 Right-click, and select Create RF Obstacle. The Create RF Obstacledialog box appears.3 Go to “To use the Create RF Obstacle Dialog box” on page 130.
