Line optimizing

[castroman]

I got a dxf file that contains tons of little line segments. I was wondering if there is a way to optimize these lines so that I get them as one object. Such as a road line, a property line and so on, so that I can bring them into viz for extruding. I am talking about a whole block of a city, so there are a tons of little segments

 

anybody got some good tips.

the only method i know of in autocad is to re-draw/re-trace the line. (unless the latest versions of autocad have this miracle cure?)

[castroman]

ok, I was worried that this was my only method. If things only was as simple as in Cinema 4d

If you mean a single line that is broken up into segments, you could try converting one segment to a polyline using the PEDIT command. Then use JOIN to attach the other segments to it by selecting the ones you require.

[STRAT]

aye, you can easily join and poly edit lines back up as a single line then re-spline and optomise the verts in max, but autocad will only give you a vertex heavey line, ie, what you see is what you get. optomising in autocad is possible but time consuming.

ok, thanx for the input, will do some testing

There are a couple of lisp files that you can (could?) get off of cadalyst's website that would optimize plines. The lisps that I tried were called "weed2" and "plreduce". It's been awhile since Iv'e used them, so I can't remember which was better. If you can't find them on the cadalyst site, I'll post them here.

If you a version over 2006 you can use a command called OVERKILL ,(sounds ridiculous), this will greatly reduce both the size of the file, and clean up the geometry, overlapping lines are joined, double lines deleted etc,

I use this wehn importing complex 2D snap shots from sketchup, which are sometimes unworkable without using OVERKILL.

[castroman]

thank you for the help

 

overkill seems to be working, will do some more testing later.

 

I tried to search for weed2 and plreduce, but couldn't find them, is it possible that you could send those over to oynesonline at hotmail com

robert - just curious how you found out about this 'overkill' ?

 

typical of autodesk, but there is absolutely no mention of it in the autocad help menu, yet that is a very useful tool....and it works great.

 

thanks for the tip !

yes its odd, you're right, there is no mention of it in Autocad help files. Very odd, but like you say, quite a handy tool.

I stumbled upon it accidentaly on a site called CBEN.net which you may know of (CAD BLOCKS etc), it was featured in "a tip of the day section", other than that there is just simply no way that i could have ever known about it. Incidentally it was just at the right time, it halfed my file size almost every time, with very little work, when working with flattened geometry imported into autocad.

Makes me wonder what other tools are in there that noone knows about!!

worthy of it's own thread, i think - "the hidden and mysterious commands and variables in autocad".

 

cben.net is a great site, but i didn't know about the tip of the day.

Hi everyone,

This is my first post here and I thought I would shed a little light on the OVERKILL command. OVERKILL is an Express Tool, so you won't find any documentation about it in the standard Autocad Help files. If you want to read up on it, you will need to go to your "Express" pull down menu and select the "Help" option from there. All of the Express Tools have their own Help files, separate from the standard Autocad tools.

 

Hope that clears things up a bit.
