Dim lines fade when selected in X1

[Doug Park]

In X1 dimension lines now highlight in the same fashion as other items when they are selected. The way this works is to take the highlight color, settable in preferences, and doing an XOR draw over the top of the existing color. XOR drawing is a way of inverting the color such that drawing again will get you back to the original color. This is a trick to make editing fast that goes back to the early days of Chief when other options were pretty much out of the question because of hardware limitations.

The trick is to pick highlight colors that work well with your object colors. It is very possible to pick colors that will produce very bad results. It is also easy to pick colors that will highlight very well. Try moving the highlight color off in the R, G, or B value of what you currently have in increments of about 20 until you get a result that is good for you.

When you do this check other objects as well. Especially, things that aren't being drawn in Black.

While the background color will come into play in this it is really not a primary player in whether you can see things or not.

In the future we will very likely replace this mechanism for highlighting with one that will be fast as well as provide good highlighting of the items being selected.
