For everyone working in the construction and design industries, have you ever had experiences like these?
The app that solves these problems with just one smartphone is the free drawing viewer app "DARE BOX Mobile" (iOS Version) (Android Version).
With DARE BOX Mobile, you can view, manage, and convert (※paid) various CAD drawings like DWG, JWW, IGES, JT, and PDF all in one place, even on your smartphone or tablet. It's an app dedicated to CAD drawing tasks.
Many drawings are data files created and edited with specialized CAD software, such as in DWG (AutoCAD) or JWW (Jw_cad) format. Unlike PDF or image files, these have the characteristic of not displaying correctly without a dedicated viewer. Especially on construction and design sites, it's common for multiple drawing formats to be mixed, like this:
If you need to switch between apps for each drawing format, work efficiency drops significantly. Furthermore, when environmental factors are added, such as not being able to use a PC on-site, you can lose time on tasks that should just be "viewing".
DARE BOX Mobile is a smartphone-compatible multi-drawing viewer that eliminates all these hassles.
Paper drawings are still used on-site, but viewing on smartphones and tablets is also becoming mainstream. We've compared the advantages and disadvantages of each.
| Comparison Item | Paper Drawings | Smartphone/Tablet Drawings |
|---|---|---|
| Portability | Bulky to carry, requires many drawings | All drawings can be stored on one smartphone |
| Viewability | Large and easy to see at a glance, but weak against wind/dirt | Easy to see details by zooming, safe for outdoor use |
| Update Reflection | Needs reprinting, hard to know if it's the latest version | Always displays the latest drawing with cloud integration |
| Ease of Sharing | Can't be shown unless you're there in person | Can be shared instantly via email or cloud |
| Cost | Costs for printing, carrying, and storage | App is free, many cloud options |
| In Case of Trouble | Risks of loss, damage, missing drawings, etc. | Can be checked instantly anywhere with a smartphone |
If you prioritize confirmation speed, information sharing, and manageability, mobile drawing viewing is overwhelmingly more efficient!
By using a smartphone app like DARE BOX Mobile, you can streamline on-site work while covering the weaknesses of paper drawings.
DARE BOX Mobile supports the main file formats used in architectural, civil engineering, and mechanical CAD !
| Supported Formats | Example Use |
|---|---|
| JWW | Architectural drawings (Jw_cad) |

| DXF | Intermediate format between CAD programs |
| SXF（SFC/P21） | Public works drawings for government agencies (electronic delivery) |
| General-purpose drawing distribution | |

Complex linetypes, layers, and text information are reproduced accurately, allowing you to check drawings on your smartphone as they are. Of course, zooming, shrinking, and swiping are smooth, and dimensions and notes are displayed clearly! No matter how detailed the drawing, you can view it without losing any detail.
The biggest feature of DARE BOX Mobile is that it can be used in conjunction with cloud storage services like Box and Dropbox.
