Overview

Describing the difference between CAD and Room Data mode.

Method

There are two methods for creating projects in Design Database - CAD mode, where you will import a DXF file and sketch your building, or Room data mode which relies on manual input.

A CAD mode project can be converted into a Room data mode project quite easily, but once you do so you loose a lot of CAD functionality and the more you use Room data mode, the less viable the CAD model will be.

To this end you are warned twice before the software will convert your project.

If you choose to ignore this message and turn off the "Use full building CAD model" you will be given a second chance to cancel this move:

If you select OK on this warning then your project will be taken out of "Full building cad model".

Once switched to Room data mode your CAD model will have far less functionality than before. The following items will no be available, for example:

• Design Simulator can no longer be accessed
• CAD will function as a simplified model
• Roof/floors will no longer be accessible in CAD input
• 3D View will no longer be accessible in CAD input

You should also note that the CAD drawing will appear in black and white, and if you add new rooms in CAD Input, that adjacencies may no longer be automatically set up.

If you have not made too many changes to your project while in Room Data mode, it may be possible to turn CAD Input back on:

• Exit the software entirely
• Back up your project
• Navigate into your project folder and locate the DBASE.JOB file
• Open the file with Notepad
• Look for a line in the project that reads #FALSE# (all caps)
• Change this to #TRUE# (all caps)
• Save the project back
• Open the software and load your project.

You should now be back in CAD Input mode. If CAD Input mode doesn't now work as you'd expect, you may have made too many changes and should revert to your Room Data project.
