Besides Civil 3D users, I know of no engineering firm that uses annotative text or dimensions in Model Space. I tend to teach people how to use it so that they know how. But I also teach them how to place text as dimensions in a layout tab since that is what I know most companies use and I don’t want the person to be thrown into a scenario where they don’t know how to do one or the other.
If you do answer “YES” Please explain how other disciplines (Structural. Electrical, mechanical) deal with your annotative text & Dims displaying in their model?

We’re using annotative Dimensions, Text, Mtext, Mleaders, Blocks and Dynamic Blocks with Annotative scaling.
With it I can draw the model once and let the scaling do it’s job. No doubling up. The dimensions don’t lie. They show up in the viewports I want them in

The annotative text and dimensions are not so frequently used but as we use them the models are designed at once. But only in some cases they are used.
