Use annotated scaled leaders to create linework.

Senior CAD Manager Richard Navales Lim shares an AutoCAD tip using annotated scaled leaders to create linework.

"I have used annotation scale since its introduction, and find it convenient and powerful when properly used. In architecture and building structure, for example, we often produce multiple scales for site development plans (1:200 and 1:100, for example). Then we create two files for the grid (one for each scale), or we end up creating two layers for different scales.
"Creating grid blocks with annotation scales will help you avoid this old routine. Yes, you can do this by creating annotative blocks and adding the desired scale, but you may still have a problem with the grid line. Suppose you want it longer in the 1:200 scale and shorter in the other, or you want the grid numbers that are closest to each other to stretch sideways and give an appropriate distance. And we cannot give annotative scale to a grid line.
"We can give annotative scale to dimensions and leaders. To do this, first create a dimension style as annotative. Then draw your grid line. Use the command Leader and make it segmented so that you can stretch it to your desired location, then assign the annotation scale. See the sample below. (Note: If you use QLeader you cannot pick the nearest grid and perpendicular, so use the command Leader instead.)"


Notes from Cadalyst Tip Patrol: This interesting tip is a work-around that uses a straightforward tool or command that is found in AutoCAD. The problem is creating grid lines for a plan view of a building — a common occurrence. The tipster has created a dimension style that is annotated. That means that as the scale of a viewport changes scale, the dimension's display size is maintained. You can apply annotated scaling to text, dimensions, hatches, multileaders, and blocks.

This sounds a great idea, but could an example file be posted please?
