paul7 Posted June 12, 2012 Posted June 12, 2012 what is the setting to tell a line to extend to the face of a pline when that line doesn't actually intersect with the pline? see image below...line 1 will extend to pline faces A and B, but how do i get line 2 to extend to those faces? i know this worked when i used autocad 2008 but i'm now using 2012 LT so hopefully it still works, i just don't remember the command name to control it. thanks.

nestly Posted June 12, 2012 Posted June 12, 2012 EDGEMODE ... which is the same option as selecting [E]dge during the EXTEND command Select object to extend or shift-select to trim or [Fence/Crossing/Project/Edge/Undo]: Quote
paul7 Posted June 12, 2012 Author Posted June 12, 2012 tried that already, doesn't work. maybe it's because i have 'LT' autocad, i don't know. thanks anyway. Quote
Blackfish Posted June 12, 2012 Posted June 12, 2012 tried that already, doesn't work. maybe it's because i have 'LT' autocad, i don't know. thanks anyway. I don't think so it's LT. The below is copied from AutoCAD Window (F2). Command: [b][color="#0000ff"]EXTEND[/color][/b] Current settings: Projection=UCS, Edge=None Select boundary edges ... Select objects or <select all>: 1 found Select objects: Select object to extend or shift-select to trim or [Fence/Crossing/Project/[b][color="#0000ff"]Edge[/color][/b]/Undo]: [b][color="#0000ff"]E[/color][/b] Enter an implied edge extension mode [[b][color="#0000ff"]Extend[/color][/b]/No extend] <No extend>: [b][color="#0000ff"]E[/color][/b] Select object to extend or shift-select to trim or [Fence/Crossing/Project/Edge/Undo]: Read what AutoCAD is asking and follow subcommands...

nestly Posted June 12, 2012 Posted June 12, 2012 Oops, unless I'm also doing something wrong, it doesn't work for AutoCAD either..... I did not know that EDGEMODE would not extend to projected edges multisegment polylines. Grip editing with OSnap tracking, and/or Apparent Intersection Osnap may be the next best solution? Quote
Blackfish Posted June 12, 2012 Posted June 12, 2012 Oops again... I'd tried with a line, not a rectangular (or multisegment polyline)... sorry... I didn't know Maybe EXPLODE before, but that's just desperation... PS. I can check this again in 2012LT tomorrow, because this release highlighted a single element from polyline, so maybe it will work... Quote
Blackfish Posted June 13, 2012 Posted June 13, 2012 PS.I can check this again in 2012LT tomorrow, because this release highlighted a single element from polyline, so maybe it will work... It doesn't work I'm surprised... That means I have almost never use extend command that way. Still feel embarrassed Quote
irneb Posted June 13, 2012 Posted June 13, 2012 Very strange indeed. I constantly have troubles with EdgeMode extending / trimming to "apparent" intersections with my lisp programs (i.e. I have to turn it off to disallow such things happening, especially with polylines). But just checked in Vanilla 2012 - and it also ignores EdgeMode for Polylines when I do so manually. Did ADesk change this somewhere? Quote
nestly Posted June 13, 2012 Posted June 13, 2012 Did ADesk change this somewhere? I also checked AutoCAD2005 yesterday after Paul reported that EDGEMODE didn't work, and it doesn't extend to projected edges outside of a polyline boundary either. Quote
ReMark Posted June 13, 2012 Posted June 13, 2012 Very interesting. Learned something new today. Thanks guys. Hey guys, it would work if that rectangle were a block. And to do so one would have to use the Express Tools command Extend to Nested Objects found under Blocks. Make sure to specify Edge then Extend. Quote

And to do so one would have to use the Express Tools command Extend to Nested Objects found under Blocks. Make sure to specify Edge then Extend. I may be missing something, but I couldn't get it to extend to the projected edges of a polyline (polygon) inside a block either, even when using the Express tools.

ReMark Posted June 13, 2012 Posted June 13, 2012 Maybe it is because my block was made up of separate lines and not a continuous polyline which I should have mentioned. Thus, we are back to square one. Quote

Thus, we are back to square one.Ah! I think that might just be it. Try converting the Rectangle (as in LWPolyline) into a 2dPolyline (I think the "Convert" command - sorry not at an ACad just now). Anyway, the 2dPoly consists of separate lines/arcs instead of vectors inside the LWPoly. so perhaps that's where I remember it extending to all sorts of places. Quote
