What gets included (and excluded) in my CAD model?

The Short Answer

Your CAD model will include all the architecture and "built-in" elements of the space, and all the movable objects that are not part of the architecture will be cleared out. Some caveats apply, so if you're scanning non-traditional or non-residential spaces, please make sure to read on!

The Long Answer

Your CAD model will be an architectural “shell” of the space captured. Doors, walls, ceilings, floors, countertops, cabinets, and other “built-in” features will all be included, but no movable objects like furniture and decor. 

Here is a fairly typical example:

Small details like electrical outlets, crown molding, HVAC systems, etc. will be modeled if they are noticeable in the scan, but we can't guarantee that they will be included as they are not always clearly captured. Light fixtures and ceiling fans are not included by default, and scanning them directly can lead to errors in the scan from camera overexposure or tracking being affected from a spinning fan.

Regardless of the complexity of the space, our goal is always to deliver a "blank slate" for you to start your project, and that you can dive in as soon as you receive the model without having to undo a bunch of work or add things that may have been missed. Here are two examples of models with more complicated architecture:

In some cases, extremely ornate or non-traditional components of the room may get over-simplified due to the nature of the system. A few examples of this might be a very complicated fireplace, very detailed stone walls from an archaeological site, or damage from a fire. As a result, the reprocessed scan (included with your Scan To CAD order, and available within the Canvas app within a couple hours after upload) may be more useful than the CAD model, because the reprocessed scan will preserve all the detail that was scanned. This is because converting this detail into CAD format would be extremely manual, and we would have to charge a lot more to convert this 100% photorealistically.

As an example, here is a scan of an archaeological site:

And here is the CAD model generated from it:

In non-residential spaces, customers often ask about equipment, piping, and other features that are not common in homes but are important to their particular job. As our Scan To CAD pipeline is trained on residential environments, it is going to (more often than not) perform far better with typical residential items like the ones mentioned above. However, these items do appear from time to time in homes, and as a rule we try to over-include vs. under-include, so our system will generally pick up anything that it perceives as "built in" and include it in the final result — regardless of whether it's a residential item or not. They may end up slightly simplified, but if it's built-in, it should be included at least in a proxy form.

We don't have as many shareable examples of commercial spaces (as they are more frequently done for companies that don't want the insides of their offices shared), but here is an example of a boat that was run through our Scan To CAD pipeline that will give you an idea:

(Note: Because non-residential environments are significantly more diverse, we can't train the system to pick out everything, so non-residential customers may run into a case where something was not included that you wish was. If something is missing from your CAD model that you think should be included, just email us at support@canvas.io.)

We do work with customers outside of the home all the time, many of whom are scanning very diverse and complicated rooms like mechanical rooms, server rooms, or factories. Overall, the customers we work with in these areas tend to be very satisfied if their goal with the 3D model is spatial planning, design, documentation, and other projects as long as an exact representation (i.e., reverse engineering) of a piece of equipment isn't the end goal. You can read more about this here: I want to scan non-residential environments.
