AutoCAD System variable: edgemode

What if the two lines do not overlap when the two lines are cut (TRIM? The common practice is to extend two straight lines to make them intersection, and then trim the operation. If there is a large number of such non-intersecting conditions in the drawing, isn't it very troublesome to cut? AutoCAD has taken this situation into consideration for us. By modifying the system variable edgemode, we can easily trim non-Intersecting straight lines.

Enter "edgemode" in the command line and set the value to 1, as shown below:

Command: edgemode
Enter new value for edgemode <0>: 1

At this time, our trim command has the function of extending the invisible boundary. We can trim any two non-Intersecting straight lines. Try again... is the effect of using an arc to crop two straight lines that do not conflict with it (you do not need to extend the arc during trim ):

 

Note: This system variable is equally effective for extended commands.
