I have to prepare dxf files prior to sending to the programmer and I always need to first chamfer all corners at ' 0' then I go back and delete all the overhanging pieces.
Is there a trim-all command. Or some better method.
Thank you.

I'm not sure of your situation, but you may try the BOUNDARY command. Use object type: polyline. That will make a nice continuous polyline which traces all your lines.
After you chamfer there shouldn't be any overhangs. Check the trim/no trim setting in the chamfer command. (Fillet with R=0 does the same job but easier (IMO)).
Good thought Jaberwok....But I'm wondering if that's the issue?
If the the OP is using the "chamfer" command with "No Trim", this would result in the overhanging lines still intact (not separate pieces from the corners), right?
I'm curious to hear from "sscarver" to see what they find.
(btw... I use "fillet R=0" too for this purpose... in a lisp routine)
** another nugget of information (fwiw) the variable "trimmode" sets "trim / no trim" for both chamfer and fillet commands

I'm working with Inventor creating sheet metal parts.
I export the flat pattern face as a dxf.
After I open it up there are some times corners that need to be trimmed away.
What I have been doing is chamfering them at 0 but then there is still a line left and i then have to delete it.
I figured that maybe there was something to remove multiple lines, or something of that nature because I know in 3d acad there is something that removes redundant redundant lines.
Or am I mistaken.

Check that what appears to be one line is not actually two or more lines in the same location.
Use Erase and a crossing window on one line - the promt will tell you how many objects have been selected. If you're sending dxf files for manufacturing, you really need to not have duplicate lines anyway.
