AEC Dimensions and Grids

When working with structural grids, differentiating between the grid line itself and other geometry within the drawing through different linetypes is done to make the drawings easier to read. Using the default OOTB setup the grid extension lines use the following linetype: CENTER2

I am sure most, if not all, of you are aware of the AEC dimensions and how simple this can be to dimension your grid lines. When using the default setup within ADT the AEC dimension lines get drawn on top of your grid extension lines. In the image below you will find two AEC dimensions; one displaying with the dimensions covering the grid extension line, the other displaying without the dimension extension:

One method to address this issue is to modify the AutoCAD dimension style that the AEC Dimension style references, or a simpler way is to just modify the AEC Dimension Style and give this an override. The following streaming video example will show you how to accomplish this.
