3D Tour Scan Session Guidelines

Congratulations on your choice of DFW360's 3D home tour modeling service for your listing. We have prepared the guidelines below to help you and your Sellers prepare for the scan session and ensure that we get the best 3D model possible of the home.

The Process 
The DFW360 3D Scan Technician uses a special motorized camera controlled by an iPad. The camera is placed throughout all rooms of the home. The number of placements can range from as low as 50 to over 200. At each location, the camera rotates 360-degrees, stopping 6 times to take images and measurements. Each placement takes about 1 minute to complete.

The camera has three separate elements: one looking up, one looking down and one looking straight ahead. The data from each location is transmitted to the iPad during the scan session. The evening of the scan session, the data is uploaded to a cloud server and by the next day, the completed model is ready.

Length Of Scan Session 
3D scan sessions take longer than photo shoots and depend on the size of the home. The larger the home, the more placements are required to properly image the home and provide Buyers with a logical flow of camera placements to tour the property. On average, the DFW360 3D Scan technician can image about 1,500 square feet per hour.

Here are several approximate scan time examples (determined by square footage of home):

2,000 sq ft = approx.1.5 hours

4,000 sq ft = approx. 2.5 hours

6,000 sq ft = approx. 3.5 hours

8,000 sq ft = approx. 5 hours

Home Preparation
In most regards, the preparation for a 3D scan session is the same as for a photo shoot:

  • The home should be clean and free from clutter.

  • All of the lights should be on.

  • Pets should be removed from the home during the scan session.


There are some important additional requirements for 3D scanning. The 3D camera “sees” 360-degrees, taking thousands of images. The model is built in software by aligning the data of every camera placement with those nearby. This alignment is absolutely essential to creating the final 3D model.


Here are the additional requirements for a 3D scan session:

  • All objects in the home must be left in place during the scan session.

  • All doors must be left in the same position for the duration of the scan. Any decisions as to whether or not to include a particular room or area must be made at the beginning of the scan session.



Location Of People and Pets During Scan Session
It is best to have no other people in the home during the scan session. The camera “sees” 360-degrees and is continually rotating and taking images. Any movements by other persons or reflections in mirrors can be caught by the camera and there is no way to know this until the final model is rendered.


If it is not possible to have the home unoccupied during the scan session, then it is essential that any persons inside the home are on a different level of the home while the 3D Scan Technician is operating the camera. Other persons inside the home must stay away from stairwells or overlooks where the camera may see them looking up or down.


When the 3D Scan Technician moves to another level, other persons in the home can switch locations to another level. Depending on the size of the home, the length of time that a level of the home would need to remain cleared is 1 to 3 hours.

After The Scan Session
You will receive an email from DFW360 the day after the scan session notifying you that the 3D model is complete and including a link to your virtual tour with the 3D model embedded.
