Hi Gemini64,

Wow, thanks for taking the time to write such a detailed reply!

I’m using FreeCad on Archlinux:

```nohighlight
OS: Linux
Platform: 64-bit
Version: 0.13.$WCREV$
Python version: 2.7.5
Qt version: 4.8.5
Coin version: 3.1.3
SoQt version: 1.5.0
OCC version: 6.6.0

```

I had worked out most of what you’d posted, and changed the constraint, but as you mentioned a few features had the exclamation point, and the hole did change in size.

I’ve used OpenSCAD a lot for my 3D printing adventures, and this is perhaps where it really shines - making a small modification! but my knowledge of ‘normal’ 3D cad is fairly minimal.

I’ve tried opening the features with red exclamation point and OKing them, but eventually FreeCAD crashes ☹

I’ll have a go at the ‘lazy way’; I like lazy ways 🕶

thanks again for your help!
