About this app

ScopeTup – A High-Performance CAD Viewer and Measurement App for JWW (Jw_cad)

ScopeTup is a high-performance CAD viewer app that allows you to view, measure, check coordinates, and mark JWW (Jw_cad) drawings on your smartphone or tablet.
It was developed to improve the work efficiency of all users who handle drawings on-site, including those in the construction, surveying, construction management, facility construction, and design industries.

No need to carry paper drawings or a laptop.
Instantly open drawings on-site and check dimensions, positions, quantities, coordinates, and share instructions on the spot.

Developed based on the concept of "looking closely at drawings (Scope)," this app significantly reduces the time spent reviewing drawings on-site, helping to improve work speed and productivity and promoting digital transformation in the construction industry.

■ Fully offline compatible (no radio waves required, on-site compatible)

ScopeTup can be used without an internet connection.

・Construction sites with no signal reception
・Underground facility construction sites
・Tunnel construction
・Mountainous sites
・Restricted communication environments

Drawings can be displayed reliably when needed, regardless of communication conditions.

Providing the peace of mind that is crucial for field work.

■ JWW (Jw_cad) CAD Drawing Viewer

・Directly load and display JWW files
・Automatically restores the display magnification and center of view when saved
・Intuitive panning and pinching (zooming)
・Optimized rendering even for large drawings

Reduces the need to turn on a PC to check drawings on-site, speeding up review work.

■ CAD Measurement Functions (Distance, Angle, Area, Arc)

Accurate measurements can be made simply by tapping any point on the drawing.

Supported Measurement Functions:
・Distance between two points
・Angle measurement
・Arc length and circumference
・Ellipse length
・Polygon area

Widely useful for checking construction dimensions, quantity takeoff, design review, and finished form confirmation.

■ Virtual Auxiliary Lines (Extension Lines, Perpendicular Lines, Arbitrary Lines)

Draw auxiliary lines on a drawing to check intersections and understand positional relationships.

・Extension Lines
・Perpendicular Lines
・Arbitrary Lines

This helps improve the accuracy of marking out and construction planning.

■ Surveying Support: Coordinate Measurement Function (For Practical Use)

Calculate the coordinates of any point by setting a base point (BP) and backsight point (BS).

Display Information:
・X Coordinate
・Y Coordinate
・Direction Angle
・Distance

Supports the survey axis system, allowing you to input measured coordinate values ​​into an optical surveying instrument or total station for use in surveying sites, stake position confirmation, marking out, and positioning work. Coordinate values ​​are displayed intuitively, eliminating the need for tedious paper-based coordinate calculations.

■ Dedicated Coordinate Calculator (Advanced Function)

You can also edit coordinate values ​​directly by entering them numerically.

・Coordinate value acquisition (GET)
・Numerical input and editing
・Calculation processing
・Coordinate update (PUSH)
・Automatic recalculation

Surveying calculations, position corrections, and construction location planning can all be completed within the app.

■ Drawing (Painting)

Mark and handwrite directly on drawings.

・Pen drawing
・Highlighter drawing (transparency adjustment)
・Cloud mark
・Rectangle drawing
・Color and line width adjustment

Ideal for on-site instructions, correction instructions, meeting notes, and construction notes.

■ Screen capture

Drawings and annotations can be saved as images.

・Full-screen saving
・Specified area saving

Saved images can be used for reports, emails, chats, and cloud sharing.

■ Layer display switching

Supports JWCAD layer and layer group display switching.

Display only the information you need, improving drawing visibility.

■ Object snap (precise operation)

Supports accurate measurements and operations.

・Endpoints
・Intersections
・Midpoints
・Centers
・Tangencies
・Line Points
・90-Degree Circle Points

Easy to use even for experienced CAD users.

■ Unit Settings (for Construction and Surveying)

Change units to suit your needs.

Distance:
mm / cm / m / 寸 / 尺 / 間 / inch / ft / yard

Angle:
degrees / radians / gradians

Area:
㎡ / tsubo / tatami / hectares, etc.

■ Display Performance Optimization

Enjoy smooth operation even with large CAD drawings.

・Level of Detail (LOD)
・FPS Display
・CPU Usage Display
・Memory Usage Display

Optimize your device's performance for optimal use.

■ Multilingual Support (for Foreign Technicians and Overseas Workers)

Currently, the instruction manual is available in Japanese and English.
The following languages ​​will be added in the future.

・Vietnamese
・Chinese
・Indonesian
・Thai
・Nepali
・Khmer (Cambodia)

Supports communication with foreign skilled workers to address labor shortages in the construction industry.

■ Intuitive operation for immediate use on-site

・Pinch to zoom
・Smooth scrolling
・Fast panning
・Easy file loading
・Touch-optimized UI

No need to learn specialized operations.

Anyone can start using it right away.

■ Practical use cases

・Dimension confirmation at construction management sites
・Coordinate confirmation at surveying sites
・Location confirmation at building sites
・Interference checking during equipment installation
・Renovation site surveys
・Drawing sharing during design meetings
・Quality control inspections
・As-built confirmation
・Quantity takeoff
・Construction review
・Process meetings
・Comparing with site photos

Contributes to improving the efficiency and accuracy of on-site work.

■ Improved work efficiency

Working primarily on paper drawings requires a lot of time for printing, carrying, replacing, and checking. ScopeTup significantly reduces the effort required for blueprint review.

- Reduced printing costs
- No need to carry blueprints around
- Reduced review time
- Accelerated on-site decision-making
- Prevented work errors
- Accelerated information sharing

Your daily work will run more smoothly.

■ Supported file formats

Compatible: JWW (Jw_cad)

*DXF and DWG files are not supported

■ Four plan options

ScopeTup offers four plans to meet your needs.

- Free plan: Free viewing mode only (with ads)
- Standard plan: Viewing mode (no ads)
- Pro plan: Viewing mode and measurement mode
- Max plan: Viewing mode, measurement mode, coordinate measurement mode, and painting mode
