Detect drawing differences and check revisions and missed changes

Compare drawings before and after revision.

Can we discuss an evaluation involving confidential drawings?

We can discuss an evaluation process suited to your drawing handling rules and security requirements. Please contact us about the conditions first, without sending confidential drawings.

How can we identify changes and differences between drawings?

Load the earlier and revised drawings, align scale or layout as needed, and compare them. Color highlights show additions, deletions and changes to dimensions, text and shapes. Save the results as a PDF to share with your team.

Can we check for missed drawing corrections?

MIIDEL helps reviewers compare drawing differences with correction instructions to check whether requested changes were made and whether unintended changes occurred. It does not automatically interpret correction instructions or determine whether a design is correct.

MIIDEL includes tools to correct differences in scale and layout. Contact us to discuss suitability for your data and how to evaluate it.
