View Full Version : 2017 Glitch or intentional behavior when using Selection Window inside the Trim command?

I just noticed that while using the trim command, Autocad (2017, 2016) will select an entire polyline if I only draw my selection window (not a crossing window) across at least 1 midpoint as well as the end point of that polyline.

It will not select it if I only go across mid points, nor will it select it if I only cross the start point and mid points of that same polyline.

I noticed it when I used a selection window to select a few lines to trim to and purposely started beyond the start point of a polyline I had in the same area. When I trimmed the lines, I noticed that they trimmed to the polyline instead of my selected lines since they were beyond the polyline.

Is this a glitch, or designed into the Autocad trim command only?
Is there a command to dissable/enable this functionality?

I hadn't noticed it before today.

To replicate what I did, draw a pline with a start, end and at least one mid point.
Then, enter the trim command and use a selection window (not a crossing window) to cross the midpoint and the endpoint.
It should then select the entire polyline.

It works fine for me here in 2017.

Make sure I'm following your steps right.

it look like from you clip there you don't understand you crossing windows. Crossing to the right only items completely in the window are selected. try crossing to the left everything touched by the window is selected

Read the first post again. The OP said "use a selection window (not a crossing window)"

You drew it right, and it works as it should, but try selecting the second and last point and see what happens. On mine, it will select the line, even if I don't include the start point.

is this line or a polyline it looks like a polyline so no completely in the window

I see what you are talking about now.
It does this on TRIM and EXTEND, but not other commands (or while no command is active) that I can tell
It's not limited to 2017 either. It does this in 2014.
