trim problem

[amanda phillips]

I have been having problems when triming to a line.

 

When i trim the line that i am trimming seems to break instead of trimming and always leaves a section of line above the trim point.

 

Did that make any sence???.... Its not easy to explain.

 

The drawing was origninally a dxf file that i have saved as a dwg file.

 

Thanks for any help

Are you trimming to an arc or circle?

[amanda phillips]

hi

 

i am trying to trim to a series of straights that i have converted to a pline.

 

[SLW210]

Can you possibly post up a .DWG file so it could be given a good look? Just the portion you are having trouble with will be fine.

[amanda phillips]

Please find attached a .dwg file showing the problem.

 

Thanks:D

Loaded the drawing and the lines trimmed ok with no problems.

Change your EDGEMODE variable to 0.

 

You will want to change it back to 1 after you finish trimming these lines.

Amanda,

sorry to say everything trims fine this end (Acad2004)

btw the supplied example .dwg

'example of what happens' isn't even trimmed to the line ??

the example given seems to show that you've trimmed one solid line only to find another with a different linetype underneath

 

choose a command such as move or copy, and use a crossing window to select your line (don't use a single click - it has to be the window) and it should tell you how many elements there are there

See my previous post. It's a simple switch of the EDGEMODE variable.

 

From the Autocad Help Files:

0 = Uses the selected edge without an extensions

1 = Extends or trims the selected object to an imaginary extension of the cutting or boundary edge

 

Your polyline has many edges, so when you select it as the cutting edge and try to trim the intersecting lines, the lines are trimming to the imaginary extensions of the cutting edge. Switch EDGEMODE to 0 and you will be able to trim the lines easily. Just set it back to 1 when you are finished trimming.

That's it right there.

why would I want to bring the edgemode back to 1..??where would you use it at the 1 setting?? Mike

[Cad64]

Setting EDGEMODE to 1 allows you to Trim/Extend to an imaginary edge.

 

For example, say you have a horizontal line and a vertical line. You want to Extend the vertical line up to the horizontal line, but the vertical line is not directly underneath the horizontal line so it will never meet the horizontal line at any point. With EDGEMODE set to 1, you can extend the vertical line up to an imaginary extension of the horizontal line.

 

Does that make sense?

[happyunited]

thats interesting

[New2CADmike]

Yes it does make sense!!...Until this thread i didnt know there was a variable of edgemode...Mine has always been set to 0,because I did not know it was there to change..Thanks again Cad 64..Mike

[Guest Alan Cullen]

But bear in mind......in some situations setting edgemode to 1 can also create other problems and results you weren't ready for......so learn about it and be careful.......

Anyone know anything else I could try? Flatten, audit, recover, changing the UCS back to W, none of those worked.

What are you wanting to do?

 

Can you post the drawing file?
