Showing Dimensions
If you're using SmartDraw's wall's tool, the actual length of each wall segment will be displayed above your line as you're drawing.
This will help you create a more accurate outline on the first try, reducing the amount of time you'll need to spend on editing.
Once your room outline is complete, you can still show the length of each wall segment by selecting all the walls and then choosing Dimensions in the Shape Properties group from the Design tab.
Here, you can set your walls to display its dimensions: "Always," "Only when selected", or "Never." Choose the appropriate option for you.
Adding Symbols
To add a symbol, click any symbol in the Library Gallery of the SmartTemplate and click again anywhere on the page to stamp it.
Adding Exits
To add exits such as doors and windows, click on the Exits button under the Build a Crime Scene part of the SmartPanel.
You should now see several doors and windows docked inside the window in the SmartPanel.
Click on a door or window you want to add, then stamp or drag it into place on your outline.

The white part of a door or window symbol is meant to replace the wall section you drop it over, so you don't have to leave an opening for it.
You can use your arrow keys to nudge it into place.
Note: You can use the Flip menu in the Shape Layout group under the Design tab to reverse the direction of a exit.
