Today, i find a software "DWG to SVG Converter MX" to convert the .dwg files to svg.
And i use software "GLIPSGraffiti1.5" to view and modify the .svg files.

We have discuss the floor plan. Listed below:
1. For example: A room a102, it is a square. It isn't only four walls. Because one wall will be separate by two straight line on the floor plan and have a unknown thing between them. We consider to name the wall from a102-wall-001 to a102-wall-004 at the first time(if it's only have four wall). Because of the cause on the above, we need to change the name. So, we decide to name the wall a102-wall-001 at start. An order is according from left to right and top to bottom to name all wall. For example: A room have eight walls, one wall separate by two straight line, it's eight line. We will name the top and left straight line to a102-wall-001, the bottom and right to a102-wall-008.

2. We also think about if a wall is share by two room, how to name it? But now we haven't any idea.

3. We will block the toilet, store room...etc. We consider to block the unimportant room, because we think no need to make an real environment for that room. It only show a door for that room.

4. If the user view out side of the campus, it only show a sky.

5. We will go to see the real environment, because we need to know what unknown thing on the floor plan.

6. I asked to sam write a java program and try to plugs-in a102 (use the .svg files include the coordinates). Because we need to change the room id, declare all wall, door......So, i call him to try one room first.
