Question 1

What measurement types does Apryse support?

Accepted Answer

Apryse supports distance, perimeter, area (rectangular, polygonal, and freehand), arc length, arc radius, center angle, interior angle, ellipse, count, and calibration. All measurement types are available across web, mobile, and server SDKs and are stored as standards-compliant PDF measurement annotations.

Question 2

Can Apryse measure CAD files like DWG and DXF?

Accepted Answer

Yes. Apryse converts DWG, DXF, DGN, RVT, and IFC files to PDF on the server, preserving layers, scale, and geometry. Measurements taken in the resulting PDF use the original drawing's scale, so a measured distance reflects real-world dimensions without manual calibration.

Question 3

How do I create measurement annotations in a web application using Apryse?

Accepted Answer

Creating measurement annotations in a web application is straightforward with Apryse. You can add various types of measurement annotations such as distance, perimeter, and area. For a detailed guide, check out the Measurement Annotations Documentation.

Question 4

Can I extract measurement data programmatically?

Accepted Answer

Can I extract measurement data programmatically? Yes. Every measurement annotation exposes its geometry, scale, units, and precision through the WebViewer API. You can iterate annotations through the AnnotationManager, filter by the presence of the Measure property to isolate measurements, and read values like annotation.Scale and annotation.Precision directly. Annotations export as XFDF (an XML standard) via exportAnnotations, and many teams store those XFDF strings as JSON blobs in their database or transform them into custom data models for quantity takeoff reports and BIM integrations.

Question 5

How do I calibrate measurements on a scanned drawing?

Accepted Answer

Use Apryse's built-in calibration tool to draw a line over a known dimension on the page (for example, a printed scale bar or a labeled wall) and enter the real-world value in the Scale modal. WebViewer applies that scale to subsequent measurements made with the calibrated tool. You can also create and manage multiple scales within a single document and assign them to different measurement annotations, which is useful when a drawing set contains views at different scales.

Question 6

Are there any video tutorials for learning how to use the measurement tools in WebViewer?

Accepted Answer

Yes, there are video tutorials available that demonstrate how to use the measurement tools in WebViewer. One useful resource is the YouTube video titled How to Use Measurement Tools in WebViewer, which provides a comprehensive overview.

Question 7

How does Apryse compare to other measurement SDKs?

Accepted Answer

Apryse differs from alternatives like Nutrient and Foxit in three areas: native CAD format support without third-party plugins, a single unified API across web, mobile, and server, and ISO 32000-compliant measurement annotation output. See the Nutrient vs Apryse comparison for a feature-by-feature breakdown.

Capabilities

Measurement Tools SDK for PDF, CAD, and Engineering Drawings

Measuring and Dimensioning

Arc Measurements

Measure curved lines using the arc measurement tool. Select a startpoint, a midpoint, and an endpoint to get arc length, arc radius, and the center angle measurements.

Object Snaps

Ensure accuracy with PDF measurement tools that snap to objects in drawings or plans. Snap to endpoints, midpoints, intersections, and more to get precise estimates and takeoffs from your software.

Image Overlay

Review changes in your document with side-by-side, pixel-by-pixel comparisons of versions.
