Hi,
I was messing about with my CUI yesterday and found that there wasn't an icon for the Mid between 2 points object snap. I had a go at making one and thought I'd share it here for others to use.
(right click and 'save picture as')
I based it on existing icons and it's basically 2 points with 2 orange arrows pointing to the mid point between them.
Unfortunately I was unable to upload it in it's original .bmp format, so I had to convert it to .png. I'm not sure if .png files can be used in AutoCAD or if it will need converting back to .bmp format.
