### 3/5 — Mouse and keyboard support

*2025-09-15*

Hello GnaCAD Team,

I’m a civil engineer working professionally on iPad, and I’ve tested your app with great interest. Its capabilities in editing DWG files and navigating drawings are truly impressive, and I believe the app has real potential.

However, there are two key limitations that currently prevent me from purchasing the full version:

1. Lack of comprehensive keyboard shortcut support. I’m referring not just to basic actions like copy and undo, but to full desktop-level shortcuts that significantly enhance CAD workflows—such as Delete, Ctrl+Z, Ctrl+C/V, Zoom In/Out, Pan, Select All, and more.

2. No support for zooming using the mouse scroll wheel. This feature is essential in engineering environments, especially when using an iPad with an external mouse.

If these two features are implemented, I’m ready to purchase the app immediately. They are fundamental to efficient daily work and would greatly improve productivity.

I hope you’ll consider this request, and I look forward to seeing these enhancements in future updates.

Best regards,    
Civil Engineer

### 4/5 — Lovely app but

*2025-04-27, version 2.7.2*

It works great, but the pen doesn’t line up with the cursor on an ipad pro. I wonder if that can be fixed? UPDATE* The issue is that the pointer is only aligned with the input pencil/finger/ mouse/ in the bottom left corner of the window. Still no fix.

### 1/5 — Not importing

*2024-08-26*

This is not opening my imported files.

### 2/5 — Abandoned? No help or manual?

*2024-05-21, version 2.7.2*

This app has a lot of potential but for the following problems:

- The app appears to have been abandoned (though the developer is still taking our money…) for 3 years.

- I’m paying for the "pro" version, but there do not actually seem to be any "pro" features.

- There is no "help" system or manual, which is a problem given that the app does not follow standard approaches to CAD and the icons have no tooltips.

- The app does not work with the Apple Pencil 2

It’s a shame because this could have been so good!

### 5/5 — ممتاز كنت ادور على برنامج يدعم 2D

### 4/5 — Lovely app but

*2023-09-09, version 2.7.2*

It works great, but the pen doesn’t line up with the cursor on an ipad pro. I wonder if that can be fixed?

### 1/5 — Will not open other dxf files

*2023-09-05*

Not being able to import other dxf files makes this program useless.

### 4/5 — Was an awesome app

*2023-06-29*

I loved this app so much that i bought it. However now my touch isnt recognized properly(registers about 10mms to the 7oclock position of where i actually touched) and i try to compensate but its just too aggravating  to keep fighting with. Whatbcan i do to fix this?

### 4/5 — 🧙‍♂️

*2023-06-04*

Pretty good but best of all is it works pretty good free, good work

### 5/5 — Great DWG viewer and editor

*2023-01-22*

I looked at several apps for editing DWG files, and this is by far the most intuitive app.   I love that you can try the the app without registration and the price is very reasonable.
