The Short Answer
While very rare, we are occasionally unable to process a scan submitted through Scan To CAD. This normally relates to one of the following:
- A scan of an object
- A scan of a vehicle or boat
- Environment (e.g. scanning in a very dark place, or in a commercial kitchen with a lot of stainless steel)
- Scans that aren't of a complete room or are missing crucial information (e.g. partial scans, scans of open spaces, vehicles)
- Poor quality scans
If a scan can not be processed, it will be “rejected” and you will not be charged for that scan. We will also contact you with more information about what happened, but in most cases, the space will need to be rescanned.
The Long Answer
In most cases, scans are good for Scan To CAD processing. If a scan is unable to be processed, it is likely do to one of the following common reasons:
Poor Scan Quality
If a scan is too messy or distorted to process, it may be rejected. This can occur for reasons such as:
- Re-scanning the same area over and over again
- Zig-zagging around the space vs. following our recommended scanning technique
- Fingers or other objects covering the camera
- Scanning too close or too far away from objects and surfaces
- Poor or no lighting
- Moving objects, people, or shadows
It is very rare that a scan is so poor it can’t be processed at all, but it does happen from time to time. If you receive this rejection reason, you can always contact support@twindo.com to find out more and ways to help improve your scan quality.
Partial Spaces
In order to create a model and correctly charge for it, we need to know where to start and end modeling. Since models are 3D, we need boundaries to know where to start and stop in the left-right, forward-backward, and up-down directions. In 2D formats we need boundaries left-right, and forward-backward. If we're unable to determine some kind of boundary such as a wall, window, door, etc., your order may be rejected.
Non-Room Scans
While Scan To CAD does process and includes many architectural details, it is not designed to process and convert objects into CAD files. Scans of objects (e.g., furniture, people, vehicles) will be rejected. We encourage you to reach out to support@twindo.com if you’re unsure.
Non-structural spaces may occasionally be rejected if they require a high level of manual human attention and QA. You can read more on this here: I want to scan non-residential environments. Will Twindo work outside of the home?
