It slices and dices like a Ginsu knife!
When working on projects, there are times where we only need a portion of our model geometry.
Perhaps we want to share some of the data but not all of it.
Perhaps we want to create a .DWG that only shows the contents of a layout viewport.
Perhaps we would like to eradicate all of the geometry inside or outside of a boundary…
In the past, to accomplish this, it usually required a combination of the Trim and Erase Commands. (Likely also included the Explode command for those objects that cannot be trimmed. :) )
In any event, it can be a slow and painful process especially if the boundary is complex.
Fortunately for us, Civil 3D (and Map 3D) contain tool that will make short work of this task. The tool is called MapTrim. In short, you define/create a boundary answer a couple of simple questions and within seconds your geometry is reduced to just the area you desired.
Check out the video below to see how it works.
