Overview

This article details how to edit existing surface data within a model.

Method

To directly change individual surface properties the best method is to use the project tree.

• Expand the room in question and drill down to see the surfaces:
  
  
  
  
  
• Right click on the relevant surface and select Properties:
  
  
  
  
• This will bring up all the details for the surface, including surface type, construction type, area and orientation:
  
  
  
  
• You can then, for instance, change an external surface to internal:
  
  

Alternatively, should you wish to change the construction type properties of several surfaces at once, you may wish to use the Global Change option - as shown in this Wiki.
