Walls: Calculate the angle based on lengths

If the customer does not know the angle between two walls, they often take three measurements, as shown in the picture below:

A = 4600
B = 2800
C = 5972

a = the angle value to calculate

The Calculate the angle based on lengths tool will calculate the angle for 'a' as you begin to draw your room.  Take the following steps:

1. Draw the two walls that you want to calculate the angle between, with the correct measurements.
   
   
2. Click the Select tool icon in the tool bar
   
   
   
   
3. Click the last wall to highlight it
   
   
4. Right-click and select Wall properties... 
   
   
   
   The angle is currently at 90.0.  
   
   
5. Click on the more options button  to the right of the Angle section.
   
   
   
   
6. In the Calculate the angle based on lengths window, enter the values for A, B and C and click OK.
   
   
7. In the Wall Properties window, the Angle will be updated:
   
   
   
   
8. Click OK.  The wall will now be adjusted to the new angle and you can continue to draw your room.
