In particular, our Difference Mask, introduced in 2017, significantly reduces the time needed to compare drawing versions. The (often few) changes are identified very quickly.
We help innovative companies
to reduce their costs in the change process
by accelerating the comparison
of Engineering Drawings.
HOW
do we keep this promise?
Since 2019, PDF layers allow users to switch back and forth between the Difference View and the original documents while zoomed in.
With the Multipage Difference View, starting in 2022, matching pages of multipage documents are automatically identified, paired, and compared.
However, when designers move drawing objects, the previous approaches no longer work. In 2026, we created a prototype that attempts to track the Moved Objects and realign them. It is available for testing by any interested companies.
You can download these two examples here.
WHY
are we committed to the drawing comparison?
Today, the definition of mechanical products is based on 3D CAD geometry. Nevertheless, the Engineering Drawing is still indispensable as a generally accepted "contract document" between design, manufacturing and quality assurance, between customers and suppliers.
Particularly to quickly identify version differences in engineering drawings, we still see significant potential for improvement. Through innovative solutions, we want to make our contribution to this.
The best example and result is our unique Difference Mask – inspired by countless own drawing comparisons. Especially with “perfect” drawings, it makes comparisons much faster and more reliable, and thus guarantees a quick software payback.
Our customers' requests have led to some real highlights: A special solution for comparing labels or the Difference View EPLAN for comparing electrical CAD documents with several hundred pages.
Our cloud solution, trimmed for maximum security, offers an attractive subscription model—even for smaller companies. At the same time, a test environment is available for interested users.
Driven by your needs and our commitment to creating the best possible, user-friendly applications, in the near future our software development efforts will focus on optimizing our new solution for comparing moved objects. The goal is to have it ready for practical use in 2027.

WHAT
do our users say?
For checking the drawings a mega thing.
With the Difference View, our engineers can see all the changes in the engineering drawings at a glance.
At latest, the assembly managers now look only at the Difference View.
My test engineers are excited.
The Difference Mask has again significantly reduced the comparison time in the change process.
Super for looking over.
The tools are a great addition to our process and system landscape.
When we migrated our labels to a new label software, your solution was invaluable for quality control. We were able to evaluate the degree of overlapping very well automatically.
So the current drawing comparison is already a good thing. If I understand correctly, with the intelligent page mapping, a newly inserted page is now no longer compared to a wrong page, right? Yes, that is definitely helpful. Very good!
For me, the monthly development of pixel coverage is interesting. In the first three months after the launch of the tool, pixel coverage has increased from an average of 60% to over 70%, which is a very good KPI.
Thank you for the independent error detection and quick support in troubleshooting!
Engine design now uses the Difference View for drawing release.
The Difference View is mainly used in Engineering, but also in Procurement and Logistics.
In an 18-page document, we found two small field changes immediately.
The direct benefit is bombastic.
WHEN
do YOU reduce your costs in the change process?
You think that YOUR company, your colleagues should also benefit from the time and cost savings of a Difference View? Then take the first step and contact us. Maybe It will also be YOUR success story ...
Following an extensive development phase, we are now offering a unique solution for automatically realigning moved objects—initially as a prototype to achieve full practical applicability.
The issue of moved objects is by far the number one topic in many discussions with our customers and prospective clients. They can now easily and free of charge test the solution with their documents on our cloud server.

Driven by our love for bicycles and the passion to help shape sustainable mobility, we develop technologies in Germany that redefine shifting and drivetrains for bicycles – from precision gearboxes to the integrated E-Drive system – for reliable e-bikes and bicycles built to perform for years. Passionate development naturally leads to a constant stream of changes. And this is where the COYODO Difference View helps to quickly identify the scope of changes and save costs.

The ECAD system EPLAN is used to develop control cabinets, electrical circuit diagrams, cabling, and fluid diagrams. For documentation and communication purposes, the entire EPLAN project can be exported to a PDF document, often consisting of several hundred pages.
Especially when users do not have access to the native EPLAN data, identifying, tracking, and documenting all changes is extremely time-consuming. The Difference View EPLAN is based on the COYODO Difference View and reduces the time required to compare two EPLAN versions drastically.
