"Mark it with a micrometer, mark it with a chalk, cut it with an axe."
It was a humorous reference to the futility we all encounter in our careers, whatever it may be.
I was reminded of this saying when I was reproducing a part that had a note indicating that a piece of standard extrusion was going to be "trimmed to fit.".
Technical translation? "Here's extra material, so you can make it fit in the field".

But how do we represent that in the print?
In truth, there are several ways you could accomplish this. The one I present here, is just one idea.
First, offset a work plane the desired distance from the edge to be trimmed, in this case, I chose the maximum of .093 inches.
|The first step is creating the work plane.|
Make sure to choose the work plane as your split tool.

Once that is done, create your drawing as you normally would. But you'll notice there's a bold line where the solid representing your bracket was split.
Now comes the trick! I'm going to make the lines representing the trimmed section dashed. This can be done by right clicking on the lines, and choosing "Properties".
|Changing the lines from solid, to dashed|
|The indicated lines are dashed!|
Here are my reasons, I only ask you to consider them.
- Splitting the part doesn't create any extra files, this approach keeps everything in the part (*.ipt) file.
- Changing the lines is easy to do, the split creates a "natural break", which prevents having to create any sketch "trickery".
- The split can be moved pretty easily, by changing the work plane's offset. This let's you represent the geometry more accurately if you desire.
So there are the reason I chose this method. Feel free to see what you think, and use this tip should you ever need it!
