Join Plines/ Eliminate Gaps?

Hi group,

What's the best way to reconnect broken Plines? I don't mean ones that
touch, (where I'd use PJ or PEDIT) but ones with large gaps created by
removing doors from walls, etc. I've done a search, but not found a Pline
specific solution.

Simon.

 

I just noticed the fuzz factor option in PJ. When set high it will sometimes
join plines together, but sometimes not... hmmm...

S.

 

Why wouldn't PLJOIN work? Just make the fuzz as wide or greater then the
door you took out.

 

Or ... for joining 3D-poly's try out my PEDIT3D from www.black-cad.de.
It will close gaps too.
Regards
Jochen

 

Check your elevations.

 

The problem I had was in setting the fuzz REALLY high so that the pline
running in the X-axis became a closed pline or polygon, albeit flattened in
the Yaxis. i.e. if I pulled the 2 center grips in the Y direction the
supposedly open pline was in fact a closed object. (Hope that makes sense.)

 

I understand what your saying but at that point I don't think any command or
routine will help. The data is obviously so messed that no automatic
solution will help. I spent 4 hours reconnecting contours in a old file. The
work had been done before wipeouts and the contours were trimmed in dozens
of places for text. The only way to do it was to draw each missing segment
manually then join the whole line.

I may be wrong. If you asked in the customization group, outlined exactly
what you want to do and provided a sample some kind sole might come up with
a program to help. I just can't envision it from what you've said so far.

Could also explore OVERKILL command. I'm not sure if it's a plain vanilla command or an ADT command, but type it in the command line and see what happens.

 

I use and teach the FILLET command with a zero radius for trimming and
making
lines extend and touch.

Hi Jimmy,


I tried your pljoinfuzz.lsp but get the following msg:


Select object to join: ; error: bad SSGET list

Ni Nick IV 7,

I use the zero radius on intersecting lines but it's the parallel ones that
are giving me problems...

Simon.

 

Overkill is great for deleting exact duplicates but does it join polylines?

Simon.

 

One of the better functions in Mechanical, AMJOIN.
Using AMJOIN, you can connect lines, polylines, arcs, or circles. You can also join overlapping entities, to form a single element.

Ah. So extending them doesn't work then ?

Nick

 

I've used it to join lines before, so long as they are within the fuzz distance, it will delete the two shorter lines and create one line from them. There are also setting about ignoring layers and linetypes and such, but I've just kept everything checked.

 

I'll give that a try, arrco, thanks.

 

Nope, extend doesn't work on parallels...

 

Just tried that w/ the fuzz factor adjusted: works great, thanks very much

If they are in line (ie would project and meet) it may be that it was
drawn inaccurate. So if you drew rectangle then trimed out a bit then
extended the ends back. The rectangle is obviously acurate.

If it was originally drawn as a multiline you may have to explode it
them extend ?

There may a lisp out there.
