"Precise Annotation Control for Large Technical Engineering Drawings"

5/5

What do you like best about Apryse PDF SDK?

I've found Apryse PDF SDK excellent for annotating piping and instrumentation diagrams. Its coordinate API is precise, so annotation positions sync accurately into our database at any zoom level. I also like the low-level control it gives me to build custom tools instead of relying on the default toolbar. Review collected by and hosted on G2.com.

What do you dislike about Apryse PDF SDK?

I hit a rendering limit where very large, dense engineering drawing diagrams can silently render as a blank canvas past a certain zoom and size. Review collected by and hosted on G2.com.

What problems is Apryse PDF SDK solving and how is that benefiting you?

We use Apryse PDF SDK to render and mark up large technical engineering drawings, where reviewers need precise, page-accurate annotations saved to our database and shared across the project. It also powers a read-only observation layer that overlays automatically flagged issues directly on the drawing, separate from the user's own markup. Handling documents at that scale and detail reliably has taken PDF rendering off my plate, so I can focus on the review workflow rather than infrastructure. Review collected by and hosted on G2.com.
