OK, so I'm using Autocad MEP 2010 and putting in some piping fittings such as 90 degree elbows up or down. When I select the elbow, then right click, I can go into Edit Plumbing Fitting Style and I see where the blocks are annotative and the box is checked. I can override the size a bit to make them a little larger.

Here's the problem I'm having. When I show the elbows on different scale viewports, they get larger or smaller based on the scale whereas my mtext that's annotative stays the same size (plotted height). Am I missing something to make the blocks have a plotted height?

They look great at 1/4" scale but, when you get down to 1/16" scale, they're pretty much a blob. Now, my thoughts on this is "1/16 scale is too small to show things like elbos up and down" but, the engineers want to be able to see them AND tell what they are.

Any ideas??
