Importing or Drawing Floor Details 79

File For optimal results, use a DWG or DXF drawing. These types of drawings Recommendations are made of vector graphics line objects (lines), which you can easily

convert into RF obstacles after importing the drawing into 3WXM. In addition, the drawing objects are usually grouped together and organized by layers, enabling the display and manipulation of similar objects such as walls, doors, and windows.

Drawings in DXF format sometimes import more easily into 3WXM. However, 3Com recommends that you obtain copies of the drawing in both DWG and DXF formats if possible, so that you can try the other format if the first format you try does not import easily.

A GIF or JPG file is a raster graphics file (a screenshot or background image), which is not made of lines. To add RF obstacle information, you must manually draw the obstacles on top of the image.

For optimal performance, use files that are around 1 MB in size or less. (A DXF file is generally about 3 times the size of a DWG file for the same drawing.)

You can reduce the file size for a drawing by pruning unneeded information from the drawing, as described below.

Preparing a Drawing 3WXM has a file cleanup feature that can help remove unwanted Before Importing It information from an imported drawing. However, the more cleanup work

you do before importing a file, the better the results will be. In addition, cleaning up a file before importing it helps reduce the file size, which in turn enhances performance when handling the file in 3WXM.

To prepare a drawing before importing it into 3WXM:

„Make sure the scale of the paper space is 1” : 1” (full size). Also, ensure that the scale type is the same as that of the model space.

„Verify that the origin point (0,0) aligns correctly for all floors.

„Delete all workspaces or paper layouts that are not required. If the drawing contains multiple paper layouts, delete all but the last one (which cannot be deleted) and delete the contents of that layout.

„Check for externally referenced files. 3WXM requires the drawing file to be monolithic. If a floor plan uses externally referenced files, significant portions of the floor plan might be missing, even with all layers unfrozen and visible.
