How do I add in points to pre-existing floorplan

The tool you're going to want to use is the "add points" tool. 

This video here  (skip to 1:28) shows how to add in the points. 

This video here shows how to set up the label. 

Here's the process:

To bring in your new equip points:

1. Make sure you are navigated to the correct floor context, 

2. use the  add points tool to bring in your new equipment. 

To get the gradient/poly:

3. Once the points are in, draw our your polys, 

4. bind the space temp points to their corresponding polys 

To get the display label:

5. drag the space temp point from the virtual points panel onto an empty space

6. right click, go to style and switch it "mini" to get the transparent look

7. right click go to tools and select short names to adjust the name. 

If you use the "add points" tool, it will automatically add that link between the space temp and the setpoint that you select in the form. 

The tool basically adds a "comparePoint" marker tag to the setpoint, which then compares it to the corresponding space temp. Just make sure to bind the space temp to the poly's, not the setpoint.
