Katherine,

We've seen this when not all heads are at 0 Z elevation. Set your UCS to World, select all heads, and in the Properties window, if Position Z states "*varies*", enter 0.

Hi Jeremiah,

Thanks for the quick response!! I did as you said-- set UCS to world, selected all the heads- they were all already at 0 z elevation.

Just for kicks I tried running the uniformity tool again with the UCS set to world... still all white.

Katherine,
You may want to take a look at the link below on why this may be happening to you. We also know this to be caused sometimes by drawing corruption and a corrupt CAD install.
Uniformity Tool: Issue With Region Creation / Colors Showing White

Thank you! Hoping for a corrupt drawing...

Be careful what you wish for. It turns out one of my coworkers is not cleaning drawings we get from consultants because she believes we may lose important information. I found corruption in a few of the XREFs. I cleaned XREFs and the drawing I'm working in to the point where the drawing I'm working in appears clean- prg, audit, and delregapps yield nothing to delete, and when I save/close/reopen that is still the case.

However. Circuiting tool is still creating white hatches, even though I did LAYDEL and purge before trying again.

Tried in fresh drawing connected to the same LFX project data-- got some hatches with color and some with white.

Tried in fresh drawing with fresh LFX test project-- worked correctly.

Corruption in LFX project data?

Katherine,

That sounds like just drawing corruption, although to be more specific, it could be that something with the drawing caused something with the blocks to be created incorrectly.
Anyway, there is a fairly easy workaround -- the region objects are created, they just aren't colored. So you could create 5 layers of the 5 colors, and select each region and move them to the appropriate layer, thus applying color to them.
There may be some other similar procedure, for instance exploding the regions and doing some other series of actions on them.
