Client Testimonials

Real feedback from professionals who protect their drawings with GhofleCad.

There were times my files had been edited without my permission. Ever since I found GhofleCad, my mind is completely at ease. It is truly a must-have for anyone working with AutoCAD drawings.

I regularly send final files to clients and always worried they might get tampered with. With GhofleCad, that worry is gone. It just works.

Most security software is complicated, but this one is both simple and effective. One of its best features is that you don't need to fiddle with tons of settings.

GhofleCad built real trust between us and our clients. No one can alter the drawings anymore and then claim they were always like that!

What impressed me was that even with the editing tricks I normally use myself, I still couldn't reach the core components after locking.

We keep a large archive of mechanical drawings and always feared the originals might change by accident. With locked files, I know what I saved is the final version.

I used to remove parts of drawings before sending them, just so they couldn't be misused. Now I send the complete file — I just lock it.

A lot of time goes into MEP drawings, and easy access to the blocks is a real risk. After locking, the file structure practically stays untouched.

It mattered to me that the file stays light and openable, yet not editable. This software does exactly that — without making the file heavy or corrupt.

I got curious and tried several times to bypass the lock, but I truly couldn't. This proves it's not a cosmetic lock — it really changes the file structure.

In mechanical drawings, blocks and details are everything. Once locked, there is no direct access to those components — exactly what I was after.

DWG files are completely open and editable — that was always our problem. This tool makes the file structurally protected while still viewable.

It works differently from anything I had seen before. Clearly it's not just a simple setting — it actually changes the file's internal structure so it can't be modified.

For control drawings, internal components shouldn't be easy to reach. After locking, the file can only be viewed — nothing more.

A big plus: no special steps, no complex settings. The output is the same file, just not editable.

I noticed that even when the file opens, there's no access to the core structure. For my AutoCAD Electrical work, that really matters.
